Sphaeropsis sapinea? on cones of Pinus sylvestris

Found this on cones of Pinus sylvestris in Brooklyn, New York. Tiny (less than 1mm) erumpant black perithecia. Conidia brown, ellipsoid to irregularly cylindric, occasionally 1-septate, but mostly non-septate. 30 - 40um by 12 - 14 um. Is this Sphaeropsis sapinea?

Lachnum on cone of Pinus sylvestris

Hi, yesterday somebody gave me this cone of Pinus sylvestris with some apothecia of a Lachnum species. I were not able to determine it (maybe L. papyraceum would fit somehow) so I'd need your help. Apothecia: stipitate, white if fresh, later staining reddish-brownish, outside completely hairy, disc up to 1 mm ø. Asci: 8-spored, cylindrical, 50 x 6 µm (unfortunately there were hardly any living asci), croziers +, IKI bb. Spores: hyaline, smooth, without any content, 6-8 x 1,5-2 µm. Paraphyses: lanceolate, projecting the asci up to 15 µm, some filled with VBs. Hairs: cylindrical, apical sometimes slightly thickened, completely incrusted, 45-69 x 3-4 µm. Best wishes, Gernot

Nectria? On needles and small twigs of Pinus sylvestris

March 06, 2007, Naro-Fominsk, Moscow region. Size of separate perithecia around 0.3mm, in clusters up to 2mm across. I think it fits the description of S. cucurbitula in Dennis, but now it's a synonym of N. fuckeliana while the latter appears to be quite different in Dennis. I was not able to find anything like aski in those on needles (conidial stage?).

Disco on bark of Pinus sylvestris

Hi, I recently found this species on the bark of a living Pinus tree. Unfortunately the material is not in good shape because the apothecia are either old and decayed or too young without any free ascospores... But I am hoping that someone might recognize it regardless. At first I tought that this species might be Cenangium ferruginosum but the micros do not fit. I attach a few photos. The first two show the apothecia. Even after rehydration they wouldn't open more than those on the first pic. Pictures 3 and 4 show paraphyses. Picture 5 shows an ascus with ascospores which appear to have an acute end. Pictures 6 and 7 show the same ascus but with a different focus to give you an idea of what the ascospores look like. Picture 8 shows a brown substance at the bottom of the hymenium. Pictures 9-11 show asci and paraphyses in IKI (asci are IKI-). Picture 12 shows what I think is a dead ascospore. Picture 13 shows the excipulum with patches of a dark brown substance. Pictures 14 to 16 show the hairs. Best wishes, Gernot

Two on Pinus sylvestris cones

Hello all, I found some productive cones of Pinus sylvestris on a coastal heath but, once again, having problems with identification. The first were perithecia, no hairs or setae present but some appeared to have slightly elongated necks. Spores were brown, 3-septate 16-20 x 6.6-7µm with narrow paraphyses. Some spores had lighter end cells. Possibly Mytilinidion decipiens, though most references i've found to that have been from Juniper? The second was erumpent - large brown spores with a germ slit not extending full length, 37-44 x 15-20 µm, no asci or paraphyses visible. Help appreciated, With regards Jenny

Tiny ascomata on Pinus sylvestris

On a dry, decorticated branch of Pinus sylvestris still attached to the tree I collected these tiny black ascomata with a somewhat lighter ostiole region. One of the most striking features is probably the reddish reaction of the ascus wall in Lugol. The asci appear to be bitunicate, ascospores are hyaline, smooth, one-celled, and measure about 12–13.5 x 4–4.5 µm. Hamathecial threads are present and appear to be cellular. I would welcome any ideas! Best wishes, Gernot

Endoxyla (?) o Pinus sylvestris wood

Hi to all My friend F.J. Balda sent me this fungus growing on very wet, semirotten, wood of Pinus sylvestris that makes groups of inmersed and blackish perithecia 0.5-0.6 mm high inside + or - developped blackish stromata. Only the blackish and roundish papilla erumpent. Asci long-stipitate up to 155 x 9 micr., with a refractive, small, IKI negative apical apparatus. The greenish-brown mature ascospores have a non-septate dark cell with an apical pore and an small hyaline cell under the wich we can to observe a very small hyaline papilla (?). If this fungus belongs to Endoxyla only E. xanthostroma is close, but the lack of yellowish tissues and the hyaline papilla of the ascospores don't fit with this species. Any idea? Thanks again

Olla on Pinus bark?

I pulled off some thick bark from a Pinus sylvestris stump and found these growing on the inner surface of the bark. The glassy, dextrinoid outer hairs would point to Olla, if I'm not mistaken.

We found this lovely little (0.8mm) disco on Pinus sylvestris. Because the elliptical spores are so small, maximum 3x2 um, I presume it's Lachnellula calycina (syn. L. resinaria var calycina?).

Dark spots and stripes on Pinus needles

These things seem to be quite common over here on fallen needles of Pinus sylvestris. I had a quick look at one spot under the microscope (400X, tap water). The asci had surprisingly (for me) sharp tips. The spores were filiform and for the first time I witnessed a spore leaving an ascus. It coiled out and then straightened. For a moment I thought that it was actually a worm :). I measured just one and it was 95 u long. At least some of the paraphyses had many septas. I'd assume this is easy to recognize from the looks alone but I have no idea about the identity of these things.

Hysterioid on Pinus bark

Yesterday I found some hysterioid fungi growing on bark of a dead, standing Pinus sylvestris tree. The fruitbodies aren't in the best condition and must've developed last season. But there were spores to be found and some asci as well. The spores have one septum and measure 27.8 - 32.7 × 8.8 - 9.5 µm. Actidium baccarinii is the best match I found, but it's spores shouldn't be nearly as big as these are. Maybe the large size is because of germination? Or is there some other alternative?

On Pinus needles

Hello again, difficulties with determination continues. Once again I'm not sure even of the genus. I thought to be collecting some Gorgoniceps, but nothing in NM1 fits. These dark based, short stipate are up to 0,6 mm wide. The hymenium is greyish brown. The spores seems to develop slowly, because I had to study many mature looking ones to find mature spores. The spores are 15-30x2-3 and develop 1-3 septas. The asci are 90-120x6-8, IKI blue and paraphyses are 2-3 wide and have multiple droplets. The cells are long and brown. Ideas? Marja

White, dark-haired on Pinus

Looking at a sample I took from a thin, dead and standing Pinus sylvestris trunk, I noticed small (ca. 0.4 mm) hairy ascos that I didn't see in the field. Initially I thought they might be Venturiocistella pini but that doesn't seem to fit. These don't have two distinct types of hairs and there was a negative iodine reaction (IKI) with the ascus pores. Also the spores are too wide. Spores: (11.7) 11.9 - 14.3 (15.4) × (2.4) 2.6 - 3.1 (3.4) µm Q = (3.8) 4.5 - 4.8 (5.4) ; N = 10 Me = 13.1 × 2.9 µm ; Qe = 4.6 Could this still maybe be something close to that?

Microthyriales on Pinus sylvestris

Hi all: I have found three species of Microthyriales on needles of pinus sylvestris, and I can't identified it. Species nº1: Tiriotecios 80-100um. Entire margin. Asci tetrasporic. Spores with lateral cilia. Species nº2: Tiriotecios 100-170um. Irregular margin, not fimbriate. Asci octosporics. Spores without cilia. Species nº3: Tiriotecios 100-160um. Irregular margin. Asci octosporics. Spores with cilia on the side and at one end. Looking at the book of Ellis & Ellis, he mentions three species on Pinus. Comparing with that, I think specie nº2 can be Stomiopeltis pinastri. The nº 1, would be similar to Trichothyrina pinophylla, but with spores ciliated and asci tetrasporic. And Microthyrium pinophyllus similar to nº3 but with cilia also at one end. What is your opinion? Thanks, Greetings SUSANA (Spain)

Lachnellula pulverulenta?

Bonjour, Nous avons trouvé une Lachnellula avec des cheveux jaunes et des granules de résine, un peu d'un couleur rouge-orange, sur les feuilles de Pinus sylvestris. En lisant la clé par Baral, c'est un genre difficile! Peut-être que c'est Lachnellula pulverulenta! Je le doute.... Hello, We found this tiny Lachnellula, with yellow hairs with some orange-red resin granules, on dead Pinus sylvestris needles. Reading Hans Otto Baral's key to world Lachnellula makes you reaslise how difficult this genus is, and how few species are in the British guides. Elllis & Ellis decribe something similar to this as Dasyscyphus pulverulenta, but it's not at all common in the UK and Ireland. The discs were up to 1 mm wide, almost sessile, very thickly covered in twisted pale yellow hairs, with resinaceous matter including some which was orange-red. (Some Myxomycete spores are also present). Spores were up to 7x2, which is a bit longer than in Elllis & Ellis. Paraphyses extended beyond the asci. It's a nice disco anyway, Cordialement, Steve

Looking at the literature and keys that I have, I get to Cosmospora rishbethii, but do not know if the determination is correct, I do not have a description of the species. Can anyone help in determining. Thanks in advance regards Susana

Orange hairy balls on Anthriscus sylvestris

Hello forum, once again I find myself in trouble with determination. These ascos are about 0,2 mm wide. The spores are about 12-20x2,5-3 and contain few small droplets. The asci are about 50-60x5-6. Hairs are hyaline, septate and microphotos once again horrible. Marja

one more disco on resin

Dear all, I found an unknown (to me) discomycete species on resin of Pinus sylvestris. Bright yellow, 0.25 mm in diam. Although I only got very sparse material, it is just enough for a little portrait. The remaining stuff will be sequenced. Spores: 16-22 x 6-7.5 µm, one celled (may be two-celled, when overmature). Asci (IKI neg.) 135 - 155 x 18 - 22 (fully turgescent). Hairs with a yellow pigment, dissolving in KOH, paraphyses small, not very capitate, septate, no exudates visible.. Any hint? Thanks in advance. Cheers, Guy

Pseudohelotium pineti?

Hello. I found these growing on needles of Pinus sylvestris. The needles were underneath a fallen branch, still attached to it. The outer surface of the fruitbodies seemed minutely hairy. P. pineti is the only suggestion I have. I measured a couple of spores and they were ca. 20-24 x 2 microns in size. The sample is not among us anymore (R.I.P.) and I only have two low quality microphotos remaining (finding more wouldn't be difficult, these seem to be common here). Can the species be confirmed with this data or are there other possibilities?

Ciliolarina pinicola?

Yesterday I found a few Ciliolarinas growing on a small branch of Pinus sylvestris that had fallen on the snow. Paraphyses with a long VB, IKI negative. The outside seemed to have short, brownish hairs. The spores measure 8.6 - 9.5 × 3.7 - 4.3 µm. I think this would fit C. pinicola, but does it ever have croziers? I think this does, although I'm not entirely sure. All of the sample was consumed, and I only have one pick of the ascus base.

Tympanis on Pinus

These little black ascos were growing on a dead, decorticated branch attached to a fallen Pinus sylvestris trunk. The primary spores appear to be first clavate inside the asci, then develop several septa, and finally split into thousands of secondary spores. Could this perhaps be Tympanis confusa, or is it even possible to tell the species? <div id="simple-translate" class="simple-translate-system-theme"> </div>

Hyphomyceto sobre Pinus

Hola. Unos muy diminutos apotecios sobre un tronco tumbado de Pinus sylvestris. Apotecios con forma de granos deformes, algunos en forma de disco con la superficie aplanada, de color amarillo limón intenso, con un diámetro de entre 0,5 a 0,8 mm. Hifas subiculares dispuestas paralelamente, fuertemente pigmentadas de amarillo, con unos conidióforos de entre 20 a 23 micras de lardo por 1,2 a 1,5 micras de ancho. Conidios muy regulares, esféricos y con un diámetro de tan solo entre 1,5 a 1,9 micras.

Hello forum members, On cones of Pinus sylvestris I found fruiting bodies with a diameter less than 3 mm. They are cup-, disc-to cushion-shaped, moist: translucent-white ; dry: pink-to purple-colored. It was not easy to make a slice because of the gelatinous texture. The spores are hyaline with an oil drop to each pole. Can this be Cudoniella rubicunda. Thanks in advance and many greetings, François Bartholomeeusen

pruinose pseudothecia on resin

Dear all, I found this beautful pseudotheciate ascomycete growing on Pinus halepensis bark with resin exudates in the eastern Iberian Peninsula. Ascomata seem to correspond with pseudothecia, and the apical openning has a greenish pruina (the photos show a whitish pruina, but it is greenish!). See attached macrophotographs. Microscopically, the most remarkable character is the presence of multispored ascii (tens of spores). Spores are rounded, small and hyaline. In fact, the microscopical characters resemble somewhat those shown by the genus Sarea, which is also resinicolous. Moreover, the unknown species has pseudoparaphyses. Molecular data are not conclusive. The more conserved LSU marker seems to point to the Lecanoromycetes, in between of genera whose species are lichenized (Umbilicaria, Porpidia, Acarospora, etc.). But the similarity is quite low (93%). However, our unknown species does not establish these symbiotic associations. Information from the ITS is not of much help. Any further insight from your side on the taxonomical identity of this species will be greatly appreciated. Best wishes, Isaac

Hola. Un muy diminuto Pirenomyceto sobre un tronco degradado de Pinus sylvestris, compartiendo espacio con la abundante Hyalorbilia inflatula. Pequeñoas granos negros con un diámetro de entre 0,05 a 0,98 mm. Peridio externo formado por unas hifas fuertemente pigmentadas de marrón, angulares y de pared gruesa. Ascos aparentemente octospóricos, con una gran cantidad de paráfisis filiformes e hialinas.

Coccomyces strobi on Pinus strobus

<div>Hello,</div> <div>Yesterday in New York City on Pinus strobus I saw what I assumed was a pyrenomycete. Tiny erumpent pustule-like fruiting bodies on a fallen branch. However, when I sectioned one of them I found that the interior is a solid yellow. Asci are 92.5-107.5 x 7.5-10µm. Paraphyses are filiform and curled at the ends. Ascospores are 30-36 x 1.5-2µm. I am assuming that this is Coccomyces strobi because of the substrate and the spore shape and dimensions, even though in this state it is probably immature (?). Any input would be very welcome. </div> <div>Ethan</div>

On Pinus sylvestris needles, found in Cantavieja (Teruel (Aragón)) in Spain. Well, at first I thought it would be Heyderia pusilla. But asci arise from croziers.

Hola a todos. Subo unas fotos de una Heyderia que he encontrado hoy sobre agujas de Pinus sylvestris. Miden unos 5 mm de altura. Esporas de 13-16,9 x 2,7-3,3 micras. Ascas amiloides, aporrincas. Paráfisis con gran contenido vacuolar de color amarillento, que se vuelve azul turquesa en presencia de cresilo acuoso. Creo que podría tratarse de Heyderia pusilla, ¿Qué les parece? Gracias por sus respuestas. Rubén

Hardware Tony, 21-04-2023

Wonder if anyone can help here with this species which I thought was Durella suecica, but is IKI -, the spores are slightly larger with larger apothecia <1.0mm. Gregariously scattered under fallen branch of Pinus sylvestris with flattish surface, concolourous margins and exteriors of pale cream colour. No marginal hairs. Ascospores: 6.53 - 8.03 x 3.31 - 3.63 µm, hyaline, non-septate, polar drops at each end, one end slightly larger both rounded. Asci: 8-spored, Unseriate 60 - 75 x 6.85 - 7.55 µm. IKI - Paraphyses: 10 µm ± above asci, cylindrical rounded tips, tapering up with 2-septa, filled mostly upper sections VB's, some highly refractive, some with granular exudate tips. Croziers: Not observed. Excipulum: Small celled subglobose texture. with many thanks for any ideas

Otidea sp

Hola. Ayer encontre esta Otidea numerosísima en bosque de Pinus sylvestris. Fructificaciones cespitosas en forma de Peziza en unas ocasiones, aisladas y en forma de oreja de liebre en otras, de color cafe con leche, sin diferenciarse apenas el himenio y el excípulo. Sin tonos oliváceos De 3-5 cm de longitud y 2-4 cm de diámetro. Había pensado en Otidea alutacea pero el hábitat y las fructificaciones no me cuadran mucho. Un saludo

This should be easy...

<div>Here is a very distinctive disco on twigs of Pinus sylvestris, from a native pine forest in NE Scotland. It appears to be erumpent from the bark and initially closed, the fruit bodies are slightly stalked and smooth on the outer surface (not scurfy like encoelioid species). They are up to about 2.5 mm diam. The asci do not stain blue in iodine. Unfortunately very few contained mature spores, but those seen are 15-16.5 x 5 µm, hyaline and aseptate. The image at lower magnification is in water, the higher mag image is in warmed lactophenol to check there are no septa.</div> <div>I have been looking around Tympanis and Godronia, but nothing seems to fit. Any suggestions would be much appreciated.</div> <div>Best wishes</div> <div>Paul</div>

pyréno immergé dans Pinus sylvestris

Bonjour, Dans une branche de Pinus sylvestris dans un été de décomposition très avancé, j'ai pu observé des ascomes singuliers rappelant en forme celle de pyrénos aquatiques : ascomes ellipsoides : de longueur 600 x 700 µm pour 400x 500 de largeur et de hauteur avec un bec latéral (sur la longueur) pouvant être très proéminent suivant le degré d'immersion. Tel le monstre du Loch Ness, il montre son cou et son dos à la surface.

Hysteriaceous asco with brown didymospores

Hi, I collected this fungus on bark of living Pinus sylvestris – ascospores measure about 25–27 x 10.5–11 µm and become 3-septate when overmature. Most other characters should be shown on the photos but if not I will check the material again, of course. I'd appreciate any ideas! Best wishes, Gernot

yellow discomycet on Pinus

Hello, I found this discomycet this year's spring on a quite fresh branch of Pinus sylvesrtis. Because of the striking colour and the big spores I thought of Amicodisca but: - the haris are clavate, not cylindrical/narrowing - the asci are IKI- Maybe someone can help me with this find.

Diplodia scrobiculata?

Hello They grew on the bark of dead pine (Pinus sylvestris). Usually, there are shown on pine needles so I have some doubts? Another species occurring on this substrate is D. Sapinea. However, according to literature, it should have much longer spores? Spores: (30.2) 31.2 - 39.5 (39.6) × (14) 14.7 - 15.9 (18.6) ?m Q = (1.7) 2 - 2.57 (2.6); N = 8 Me = 34.8 × 15.7 ?m; QE = 2.2 I marked well? Greetings Mirek

Chris Yeates, 19-07-2012

is this Hysterobrevium smilacis?

I struggled for a long time with this before "the penny dropped" - the shape of the ascoma being very short; this was a solitary pseudothecium on a fallen twig of Picea abies (non-native in Britain); ascospores 21.2-26.2 x 8.3-9.1µm; I have run it through Boehm's key and arrive at Hysterobrevium smilacis; comparison with Alain's http://www.ascofrance.com/search_recolte/2649? shows very similar ascospores. My only reservation is the substrate - I can see that this taxon is highly plurivorous, but it has not been recorded (as far a I can see) on a Gymnosperm in Britain. Is that a problem? Cordialement Chris J'ai lutté pendant longtemps avec cela avant «ça a fait tilt», la forme de l'ascoma étant très courte?, ce qui était un pseudothèce solitaire sur une brindille tombée de Picea abies (non-natif de Grande-Bretagne); ascospores de 21,2-26,2 x 8,3-9.1?m. Je l'ai parcouru le clé de Boehm et arriver à Hysterobrevium smilacis; comparaison avec http://www.ascofrance.com/search_recolte/2649 d'Alain ?montre ascospores très similaires. Ma seule réserve est le substrat - Je vois que ce taxon est très «?plurivorous»?, mais il n'a pas été enregistrée (d'aussi loin que je peux voir) sur un gymnosperme en Grande-Bretagne. Est-ce un problème? PS how do you say «plurivorous» in French?

Mollisia on Pinus

... found in Northern Germany (Brandenburg, Schorfheide-Chorin) on Pinus. The apothecia appeared bluish (maybe more in the sunlight) to me. The asci react blue in IKJ, and bear croziers, the paraphyses do not (or very slightly) react with KOH. The dark excipulum doesn`t have well developed marginal hairs. The spores are not very distinct, but quite large, about (8,5)-11-14/2,8-3,5 µm. Can somebody give a name - or is it quite hopeless? "Cinerea" in wide sense ... Best regards, Lothar

Helotiaceous fungus on male cones of Pinus radiata

Hi to all Last week-end we have collected these small, gregarious, pale witish or amber (when old), subturbinate or shortly stipitate up to 1mm high and 0.7 mm broad ascomata growing on male cones of Pinus radiata lying on the wet ground. It seems to have any blackened stromatized zones at their insertion on the host. The hymenium is never convex but it is plane to slightly concave. The ascospores are smooth, broadly fusiform and they seem to have 1 nucleus. Asci with croziers, 8-spored, with an apical apparatus weakly euamyloid, very difficult to observe and I don't know their type (Sclerotinia-type, Hymenoscyphus-type?) .. Living paraphyses with many rounded Vb's, hyaline to yellowish. Ectal excipulum is built by roundish to vesicular cells in a tetura globulosa-subangularis. No hairs in the apothecial margin; only cilyndrical to subclabvate elements with the same Vb's. I think perhaps this fungus belongs to the Sclerotiniaceae or Helotiaceae. I'm not sure... Many thanks for help me Enrique

Gorgoniceps aridula / viridula

Good day everyone, have collected some data to Gorgoniceps discussion there (http://www.ascofrance.com/search_forum/10583?). I have two specimens which could be named G. aridula and G. viridula by spore septation, but other characters not clear. There was not green pigment in tissues, no difference in spore and asci size. The substrate of my two specimens was different (pine bark and pine wood), but what i've named G. aridula was from bark, and G. viridula on wood. There was significant difference in color of exsiccata (dry apothecia), they were grayish color in a specimen from wood (named G. viridula) and much darker, reddish-brown in a sample from bark (though alive both were the same grayish color). So, there are descriptions and pictures of them separately below: Gorgoniceps cf. viridula Collected from pine wood (Pinus sylvestris) at bog, 07.09.2012, N61,066591° E69,457326°. Apothecia 300-500 mk wide, 200 mk high, turbinate, gray, with outer surface the same gray or brownish in different specimens, hymenium minutely rough, with some adherent released spores (dry exsiccate light gray with slight green tinge). Excipulum from textura porrecta, hyaline or dark brown in different specimens, hyphae thick-walled, 3-3,5 mk broad; asci clavate, clamped, 126,7 (113-152) x 13,4 (12,2-14,6), with amyloid pore; spores filiform, 7-septated, with acute base end and obtuse upper end, some with buds arising at both ends, 72,5 (65-82)x 2,4 (1,8-2,8) (20 stright spores, spore septation was checked in three apothecia).

Peziza cf ampelina

Hi. I would like some opinion about this Peziza found a few days ago on humus Apply Thuja, Pinus sylvestris, Acer pseudoplatanum. The violet-purple coloration of the hymenium, the latex opal and microscopic data suggest me Peziza ampelina, but in the literature indicate fungal spores 19-21 x 10-11 with two guttae (which can be seen within a few asci .) Thank you very much. Greetings Alberto Román.

On Pinus cone

Hello, I have here some Rhytismatales on a cone of Pinus sylvestries, collected in Moravia. Asci 137-228 x 10.5-15.3 micrometers, 8-spored, IKI-, H-, with a very thin lower part, pars sporifera 53-62 micrometers. Ascospores 28.2-34.1 x 3.1-4.3 micrometers, Me = 30.6 x 3.6 micro, Q = 6.7-10.1, Qm = 8.5, hyaline, aseptate, multiguttulate, enveloped in a sheath, with an empty area in the middle /nucleus/. Paraphyses hyaline, without VBs, septate, richly branched, very variously shaped, at apex 1.1-5 micrometers. Excipulum consisting of textura angularis, cells hyaline, 3.8-8.5 x 3.2-7.3 micrometers. Using the key to Rhytismatales on conifers by D. Minter, I arrived to Lophodermium, but ascospores of all the species are much longer than in my find. Searching in the genus Colpoma is so far unsuccessful as well. Advice will be welcome. Thank you, Zuzana

white Lachnum on Pinus cone

Bonsoir tous I expected this collection to be a straightforward Lachnum virgineum, but it lacks the prominent lanceolate paraphyses of that species and, along with other characters, the spores differ. Apothecia clustered towards the proximal end of a cone of a Pinus sp. (planted, non-native). Asci 8-spored, J+ (MLZ used here - a slip, I had intended Lugol), croziers present (arrowed). Ascospores ellipsoid-fusoid 10.5-11.7 x 3.4,3.8µm (Qe = 3.1). Hairs ornamented along full-length, cylindrical, not expanding at apex. Ectal excipulum of very small,rather thick-walled, and narrow cells, becoming maze-like at junction with stem, and very narrowly parallel in stipe (see images). Any suggestions and/or help very welcome. Chris

Hi, I lately studied P. nigra pine needles suffering blight symptoms. Could this be Sphaeropsis sapinea? based on literature the conidia are not septate, however in some literature cases of one septate conidia are present too. Another possibility that I came throu is Phoma acicola? No measurings taken yet. Thank you. Souhila

Pine Cone Coelomycete?

Hi, I found these very nice spores in a rather indistinct semi-immersed Coelomycete (?) on the base of a Pinus sylvestris cone at Longshaw Estate, Derbyshire, Northern England. They are somewhat similar to Hepalocystis berkeleyi (no. 840 in Ellis and Ellis) which has two septa and square appendages and is on Platanus. The brown biseptate spores were about 12-15 long, 7-8 wide, with hyaline appendages up to 7 long. In addition there were numerous hyaline bigutullate conidia 6.5-8 x 3-3.5. I found some asci which were up to 12 wide. Does anyone recognise these beautiful spores – they aren't on Pinus in Ellis and Ellis. Regards, Steve Bonjours, J' ai découvert ces très belles spores dans un coelomycètes (je crois) sur la base d'un cône de Pinus sylvestris à Longshaw Estate, Derbyshire, nord de l'Angleterre. Ils sont assez semblables à Hepalocystis berkeleyi (no. 840 dans Ellis et Ellis) qui comporte deux septa et se trouve sur Platanus. Les spores biseptate bruns étaient environ 12-15 de long, 7-8 de large, avec des appendices hyalins jusqu'à 7 microns. En plus il y avait des nombreuse conidies hyalins bigutullates 6.5-8 x 3-3,5. J' ai trouvé quelques asques qui étaient jusqu'à 12 de large. Est-ce que quelqu'un reconnaisse ces belles spores - ils ne sont pas sur Pinus à Ellis et Ellis. Cordialement, Steve

¿Melaspileella?

Hola a todos. Tengo estos hogos que he recogido creciendo sobre ramas sin descortezar de Pinus uncinata a unas altitudes entre 1900-2100 m. Los hongos son macroscópicamente y microscópicamente, prácticamente idénticos a Melaspileella proximella. Solo encuentro diferencias en las esporas que no tienen flagelos en los extremos. Como en M. proximella los flagelos se pierden cuando la muestra es vieja y también está citada en Pinus, pensé que serían hongos muy viejos en los que ya habían desaparecido los flagelos en las esporas, pero al añadir tinta china porque había algo sospechoso en los extremos, he visto que en éstos hay como unos discos gelatinosos, que no aparecen en los extremos tanto en las esporas que conservan los flagelos como en las que ya los han perdido de M. proximella. Pienso que tiene que ser Melaspileella, ¿alguien me puede ayudar a identificarlo? Saludos. Salvador.

Phaeohelotium sp.

First identified this specimen as Phaeohelotium nobile with Nordic Macromycetes; then picked the key by Bernard Declercq from the previous discussions, and there it came to [P. pilatii] or probably P. monticola. I do not see clear clamps there (i would say clampless), spores with gelatinous sheath (but not always), and there are abundant budding at maturing. Collected on pine wood (Pinus sylvestris) in bog, N61,066591° E69,457326°, 07.09.2012. Apothecia turbinate, with short stipe, hymenium surface convex, growing in clusters (2-4), 2,5-3,5 mm in diam, hymenium surface bright yellow, smooth, outer surface yellowish, pale, brownish at stipe base. Outer layer of excipulum from textura globosa (at base) to porrecta (edge), from thick-walled cells; asci cylindrical, long, with amyloid pore, about 167 x 9; spores very variable in shape, disarticulating in two parts, and budding when overmature, with gelatinous sheath (not in all spores), with several medium guttules and amorphous oil content, 1-2 septated when overmature, mean shape fusoid, with obtuse ends, measurement for 10 mean spores: 14,2 x 5,3; conidia at long stalks, 5 x 3; paraphyses cylindrical, not enlarged to the tip, rarely branched, many segmented (about 5-7 septa), without or with some minor guttules in upper part (but bad seen in rehydrated stuff), about 150 x 2,3.

Apothécies, brun-noirâtres à l'extérieur et brun-ocre jaune à l'intérieur qui m'ont fait penser à lividofusca. Mais je n'ai pas reconnu celle-ci à la coupe. Asques bleu très net au Melzer.

Dendrodochium?

These tiny yellow sporodochia grew on cones of Pinus sylvestris. I thought it might be the conidiomata of Dendrodochium citrinum, but the conidia are cylindrical and not minute and spherical. I have not been able to find keys to this genus. Do you have any ideas that could help me? Many thanks in advance.

Black disk-shaped asco on Pinus, Dactylospora?

Hello all, Found yesterday in a New York City park on decorticated pine (Pinus strobus?). There are red pigments in the excipulum. Reddish brown pigments in the epihymenium. These seem to dissolve in KOH and produce in a yellow liquid. The asci are broadly clavate -- almost saccate. A large portion of the ascus stains blue in Lugol's, not just the tip. Spore are brown, one septate 8-11 x 4-5µm. Paraphyses are septate ending in broad cells. I had a thought that this might be a non-lichenicolous Dactylospora, but I can't find anything that fits. Can anyone point me in the right direction? Thanks, Ethan

Bonjour. J'ai trouvé sous un tas de feuilles de noisetiers, sur un cône de Larix decidua (Mélèze), tout un groupe de ce que je pense être Dasyscyphus virgineus. Question 1 : Est-il possible de trouver cette espèce sur cône de mélèze? Question 2 : Existe-t'il d'autres Dasyscyphus blancs venant sur cônes de mélèzes ? Question 3 : Dasyscyphus est-il synonyme de Lachnum ? Ou est-ce deux genres différents? Merci par avance. Yannick Mourgues

Associated with Sphaeropsis sapinea?

Hello all, I noticed a gelatinous substance on cone scales of Pinus sylvestris, in many (but not all) cases associated with black perithecia. Spores / conidia from the black perithecia were light brown, simple but some faintly 1-septate, 29-37 x 15 µm - smaller than those suggested by Christian Lechat as Sphaeropsis sapinea in different post, but within the size range for that species? Conidia from the gelatinous substance were hyaline, c. 24-29 x 3-4 µm. Are these from a different fungus? With regards, Jenny

Odontotrema minus

Odontotrema minus - probably, since it has broad asci, thick apical cap which deffusely J+ blue, spores ovoid, and apothecia immersed in wood, hemispherical, with serrate pore. It grew on decorticated bleached wood of standing-dead pines (Pinus sylvestris) (N61,054422° E69,456725°). Apothecia submerged in wood, spherical to deep cupulate, up to 300 mk wide, hymenium grayish, yellowish, smooth, outer surface rough, dark brown, radially splitted. Excipulum from thick mass of cylindrical hyphae (not well distinguishable); asci bottle-shaped, bulged in the middle, extending in length when mature, clampless, near 60 x 15 mk, wall of ascus with amyloid reaction in upper part, pore inamyloid; spores ellipsoid, 3-segmented when mature, 12,7 (11,4-14) x 5,7 (5,3-6,1) mk; paraphyses filiform (1 mk thick), rare segmented at base. I used the key in: Sherwood-Pike, M.A., 1987. The ostropalean fungi.

Hamatocanthoscypha blanc sur cône pourri d'épicéa (Picea abies)

Sur le cône pourri d'épicéa où se trouvait Hamatocanthoscypha uncipila ainsi que l'Ombrophila, il y avait un petit asco blanc très abondant que Timo Kosonen m'a demandé de regarder. Je suis presque sûr que c'est Hamatocanthoscypha uncipila, à un stade plus jeune ? La microscopie en tout cas est identique ! a) spores en forme de menhir (étroitement ovales-subfusiformes), avec 0-2 microguttules : 7-8,5x2-3 b) paraphyses filiformes, à contenu moins réfringent que Hamatocanthoscypha uncipila c) poils crochus au sommet Zotto, Timo, qu'en pensez-vous ? Bernard ___________________ On the rotten spruce cone whereabouts Hamatocanthoscypha uncipila and the Ombrophila, there was a small white asco abundant that Timo Kosonen asked me to look. I am pretty sure it is Hamatocanthoscypha uncipila, at an earlier stage? Microscopy in any case is identical! a) spores shaped menhir (narrowly oval-subfusiformes), with 0-2 microguttules: 7-8,5x2-3 b) paraphyses threadlike, less refractive to content that Hamatocanthoscypha uncipila c) hooked hairs at the top Zotto, Timo, what do you think?

Sowerbiella imperialis

Hola. Unos supuestos ejemplares de Otidea recogidos el 3 de Octubre bajo Pinus sylvestris y a 1600 metros. De unos 5 o 6 cm., con un rudimentario pie sin costillas, de color amrillo limón en su parte interna y tonos más pálidos en la parte externa, con forma de copa. Pelos externos hialinos, muy septados y terminando en formas redondeadas. Excípulo medular de textura intricada. Excípulo ectal de textura globulosa angularis. Ascas octospóricas sin reacción al melzer del aparato apical y con croziers en su base. Paráfisis filiformes, algunas algo sinuosas y ligeramente ensanchadas en el ápice Ascosporas elipsoides, lisas, bigutuladas y con unas medidas en agua de: (11.5) 11.9 - 13.2 (13.6) × (6.2) 6.4 - 6.9 (7) µm Q = (1.7) 1.8 - 2 (2.1) ; N = 30 Me = 12.6 × 6.6 µm ; Qe = 1.9 Siguiendo las Claves del género de 2017 me conducen a la Otidea concinna propuesta, pero hay algunos detalles que no me encajan, el primero estos pelos externos que no he encontrado a ningún autor que los cite, luego el color del ejemplar deshidratado ya que se cita en el mismo documento un color amarillo pálido y en este caso su color era anaranjado muy intenso, además las esporas variarían en anchura en mi caso de (6.2) 6.4 - 6.9 (7) µm. y según el mismo documento deberían medir (5–) 5,5–6,5 ?m. es decir que no lo tengo nada claro. Cualquier opinión por vuestra parte será bien recibida. Muchas grcaias de antemano. Saludos cordiales.

Calycellina cedricola?

Hello, I'm trying to identify this tiny white discomycete that grows on old needles. I've observed it twice around Ottawa, ON, Canada in late fall. The first time on needles of Tsuga canadensis on Nov 5, 2020, and the second time on needles Pinus strobus on Nov 11, 2021. It is very distinct, with helicoid marginal hairs with VBs and small biguttulate spores. Apothecia are 0.2-0.5mm in diameter, stipe 0.1-0.4mm. Asci 8-spored, IKI bb, croziers(+). Ascospores ellipsoid, with two guttules that probably always touching the wall, measure 4.9 - 6.2 × 2.2 - 3 µm I'm thinking these could be Calycellina cedricola, but I've only seen a few pictures from Zotto's drive and I couldn't find any description of the species.

Sowerbyella

Hola amigos. Se trata de mi primera intervención en el foro, así que espero no cometer errores. Disculpad que me exprese en castellano ya que mi dominio del idioma francéo o inglés es muy limitado. Vamos con la pregunta. Hace unos días encontramos esta Sowerbyella entre Cistus, justo en el borde de un bosque de Pinus sylvestris de ambiente mediterraneo. Pensamos en Sowerbyella rhenana, pero nos queda la duda sobre la morfología de las parafisis que no son curvadas, aunque hemos encontrado algún documento que indica que pueden ser rectas o curvadas.

Dried to an amber color. Small, less than 1 mm diameter. Micrographs in Melzer's. All parts inamyloid, spores measuring ( 9.8 ) 10.1 – 11.5 (12) × (2.4) 2.7 – 3.1 (3.4) µm. Q = (3.3) 3.4 – 4.2 (4.5).

Fusarium

In Arcon, le Gué de la Chaux, on attached Pinus sylv. twig in ca. 1 m above ground, grew this Fusarium. Sporodochia 0.6-1 mm diam. Is it possible to recognize a teleomorph genus, or a species? Zotto

Pop-up disco on Pinus cone

Here's a puzzle from a few years ago <a title="images" href="http://www.bioimages.org.uk/html/Stictis_sp_nov.htm" target="_blank">http://www.bioimages.org.uk/html/Stictis_sp_nov.htm</a> The apothecia popped out of cracks in a the cone scales when the cone was wet but almost completely disappeared on drying. Apothecia: elliptical in outline, gelatinous, immersed, bursting through split in surface when moist, retracting again as they dry out. Hymenium pale greyish with whitish pruina; margin darker, brownish grey. Asci: up to 210µm, tip not bluing in iodine, with 8 ascospores in a fascicle, but not completely aligned. Ascospores: long, cylindric, multi-septate so the numerous individual cells look more or less square. Brian Spooner reports that they disarticulate into part spores c.4µm long. Paraphyses: thin-walled, cylindric, very narrow, dichotomously branched twice near base, strongly expanded at apex into one to several, septate, moniliform but rarely branched, agglutinated, clavate cells (4-6.5µm diam); agglutination very strongly blued in Melzer's Iodine. Lophodermium conigenum and Naemacyclus fimbriatus: ascospores not divided enough, paraphyses wrong (as they are for Sticta spp. Also the paraphysis tips blue in iodine rather than the hymenium base) Probably not a Stictis. Schizoxylon might be better. Many thanks for any comments.

Mollisia - Tapesia ??

Bonjour à tous Quelques individus de ce petit discomycète ont été trouvés sur bois mort de Pins (Pinus sylvestris). Les apothécies sessiles reposent sur un tapis d'hyphes brun-sombre et mesurent guère plus d'un millimètre de diamètre. La surface hyméniale blanchâtre ou pâle, concave contraste avec la marge et la surface externe brunâtre. Microscopie: Asques octosporés (à spores irrégulièrement disposées), IKI+ (faible au niveau du pore) mesurent 42-50 x 4,5-5,5 µm. Spores étroitement fusiformes et peut être légèrement courbes mesurant 6 - 8 x 2 µm. J'ose tenter une diagnose mais sans aucune certitude: Tapesia strobilicola.Pouvez-vous confirmer ou infirmer ?

White dots on pine

Hi everybody, A week ago in my fiels trip I noticed some small white dots (~1 mm in diameter) on the bark of a pine tree; This occurs at the Park in Monsanto, Lisboa, Portugal; I was convinced that it was a myxomycete emerging; I collected a sample and keep in moist habitat inside a transparent box at room temperature; Now, analyzing it I got the surprise of whatching at a ascomycota; I create an observation at Biodiversity4all, where you can see details of the microscopy: https://www.biodiversity4all.org/observations/100884210 For the smooth spores I got the following dimensions: (17.2) 18.2 - 20.6 (21.3) × (10.2) 10.3 - 12.1 (12.6) µm Q = (1.6) 1.63 - 1.8 (2.1) ; N = 23 Me = 19.2 × 11.1 µm ; Qe = 1.7 Any help for the identification?

Hi, I would say that this is (in accordance with Reblova 1999) Helminthosphaeria carpathica. The spores are little less and the host is not wood. I found them on the rotten liana of Vitis silvestris. Eccentric septa is very typical.

¿Zoggium mayori?

Hola a todos. Tengo este hongo que he cogido creciendo en estróbilos de Pinus pinaster sobre el que os quería hacer una consulta. Ascomas alargados de (452,62) 496,06 - 639,94 (652,87) x (174,56) 179,34 - 368,74 (406,66) µm, con una fina capa negra exterior blanda, (de consistencia no carbonosa), con el himenio negro expuesto al exterior, creciendo en estróbilos de Pinus pinaster. Ascas de (110,53) 111,93 - 132,29 (137,50) x (9,33) 9,56 - 10,80 (10,81) µm, claviformes, bitunicadas, con croziers en la base y la endotúnica que con el paso del tiempo se va coloreando de marrón, terminando por ser casi negra cuando ya no tiene las esporas dentro (pienso que es debido a esto el color negro de los ascomas). Esporas de (69,86) 71,71 - 99,59 (100,66) x (2,48) 2,55 - 3,01 (3,03) µm, filiformes hialinas o ligeramente marrones, con hasta 20 septos transversales, poco o nada constreñidas en los septos. Paráfisis hialinas, ramificadas, septadas y muy constreñidas en los septos. Lo único que se me ocurre es Zoggium mayori. Aunque la morfología de los ascomas no encaja, las ascas y esporas encajarían con la descripción y dibujo de Zogg (1952) para Lophium mayori. No sucede así con la descripción de Vassiljeva (2001) donde dice que las esporas tienen 7 septos transversales. ¿Pensáis que mi hongo podría ser Zoggium mayori? Gracias. Saludos. Salvador.

unknown asco with hyaloscypha-like hairs

Dear collegues, due to the long lasting rainfalls in the last weeks we have quite a good season for inoperculates in the calcareous Mesorometum and Xerobrometum at the moment. In such a biotop with many orchids and some scattered Pinus we found yesterday a strange discomycete, which reminded me at first glance at Hyphodiscus, probably due to the dark brown hymenium and the somehow pubescent or rugulose excipulum. Unfortunately the collection got detoriated very soon, so that I think it might be a xerotolerant species fallen to the ground. This might be also supported by the fact that the asci are IKI-negative. The macrofotos shows rehydrated apothecia, but they look quite similar to the fresh collection, except that the white-pulverulent excipulum was not as distinct as on the foto. The haris bear some resinous exudat or may be flat cristals, I couldn't see that too good. They are slightly thickwalled an slightly brownish at least some of them. Excipulum a textura angularis with encrustations, reminding me a bit at Catinella olivacea Asci remarquable by their strange shape, quite small but broad, 8spored, IKI-negative. Spores elliptical, approx. 5-6(7) x 2-2,2 µm, oil content 1-2 Paraphyses simple as far as I could see Can someone give me an ida where to search? thank you and best regards, Andreas

Peziza sp (grupo violáceas)

Hola a todos/as Peziza recolectada en el sur de España, en bosque de Pinus pinaster con suelo de peridotitas (ácido), Altitud 1170 metros, crecían en los márgenes de un curso de agua, en el suelo y en restos degradados de Pinus pinaster y plantas del genero juncáceas (Juncus sp). Ascomas de hasta 1,5 cm de diámetro, himenio de cocol violeta este puede variar según el grado de humedad, parte externa bastante más clara que el himenio. Carne concolor con la parte externa, al corte no segrega látex, presenta algo de líquido acuoso trasparente. Ascosporas elipsoidales, bigutuladas, con núcleo central, en Azul de Nactofenol (CB) parece que presenta un retículo incompleto.

Ápice: (5,0) 5,7 - 6,9 (7,1) µm El contexto presenta dos capas bien diferenciada, un subhimenio con hifas más o menos paralelas y excípulo medular y E. ectal de textura globosas. Creo que corresponde al grupo de pezizas violácea, sin presencia de látex y de hábitat no pirófilo, pero ninguna de las especies consultadas cuadran con esta recolecta.

In view of the features shown in the photos, I think it could be Pseudohelotium sordidulum, but the shape of these spores seems more asymmetric. What do you think? Thanks, greetings Susana

About a Ciliolarina

Bonjour à tous, Hi to all, I collected on burnt Pinus wood this Ciliolarina with a strong reddening reaction to bruising with the following micro features : Ascus 40-44 x 6-7 , with croziers but no Iodine reaction (nor IKI or Mlz) Spores fusiform with polar lbs, staining violet in CRB many paraphyses with a verruculose end , homogenous vacuole staining blue-green in CRB marginal hairs 20-30 x 4-6 These would match Ciliolarina chamaeleontina (Peck) Raitvir but for the lack of iodine reaction. Would someone give a help ? Amitiés Michel

Ayuda con un Pleosporal

Hola. Un Pleosporal del pasado viernes sobre la superficie de una piña de Pinus halepensis. Ascos octospóricos, uniseriados, sin croziers observados en su base. Paráfisis filiformes, hialinas y algunas ramificadas, sobresaliendo por encima del nivel de los ascos. Ascosporas moriformes de color marrón, con un constreñimiento en su parte central y con entre 5 y 7 septos transversales. Las medidas de las ascosporas de: (19.4) 20.5 - 25.9 (28.5) × (7.3) 8.2 - 10.8 (11.2) µm Q = (2.1) 2.2 - 2.9 (3.1) ; N = 31 Me = 22.8 × 9.2 µm ; Qe = 2.5 Atendiendo a loa datos obtenidos, he considerado una posible Pleospora, atendiendo al documento del género Pleospora de Sydowia_45_0167-0187, no he encontrado ninguna que encaje con mi propuesta, con lo que hasta dudo del género. Cualquier propuesta será bienvenida. Muchas gracias de antemano. Saludos cordiales.

Pezicula eucrita ?

Voici un champignon récolté dimanche 28 novembre 2010 dans la Forêt de Fontainebleau sur un tronc décortiqué de Pinus Sylvestris. Je pense à Pezicula eucrita. Fructification 0,3 – 1 mm Ø en forme des disques épais, jaune – orangés, à surface pruineuse et avec un pédicelle très court, épais, s’évasant vers le haut et de couleur foncé. Malheureusement je n’arrive pas a faire une coupe dans les champignons de petites tailles. Spores 30 – 35 x 7 – 9 microns de trois à six cloisons En plus des spores secondaires j’ai trouver un grand nombres de conidies. Existe-t-il une anamorphe de P. eucrita ?

Hello all, friends brought me a small pyrenomycete on rotten wood of Pinus, appearing beige-brown when young and reddish black when old. Under the micriscope the wall is yellow (young) to deep orange (old). Of course I thought on a Nectriaceae, but it has long filiform pseudoparaphyses. Can Chaetosphaeria/Zignoella have such a coloured wall or what else could this be?

Durella cf. atrocyanea

Hello colleagues, i would like to post some findings from West Siberia, if it is appropriate: Durella cf. atrocyanea? (but the spores are narrower, probably undeveloped since most were inside the asci). Was collected on decorticated pine branch (Pinus sylvestris), N61,054422° E69,456725°. Frb pulvinate-cupulate, reddish-brown, up to 500 x 150 mk, hymenium surface flat or convex, smooth, outer surface smooth, the same color, brownish at the base. Excipulum from textura porrecta, hyphae at the edge obtuse, not enlarged; asci large, enlarged to the tip, tip conical, with amyloid pore, with scarce clamps, 117 (104-135) x 9 (8,3-10,5) mk; spores fusoid, some bent, some obtuse from one end, 1-3 segmented (well seen in melzer), with several round guttules, 18,7 (14,2-23) x 3 (2,5-3,5) mk [10 spores: mean, min-max]; paraphyses cylindrical, branched, 1,5 mk broad.

Small black fungi on cones of Picea abies

Hello, I found several fungi on cones of Picea abies. Here are the two species I couldn't identify: Fungus 1: Black, circular, erumpent Conidia: fusiform, 2-septate, pale coloured, 8-10 x 3-3,5 µm Fungus 2: Black, hysteroid, erumpent Conidia (Ascospores?): hyaline, long cylindrical, 20-50 x 2 µm I also observed conidia of similar colour, shape and measurements, but with tapering ends. I think, Lophodermium is possible, but the species on cones and needles of Picea and Pinus I found in the literature have longer spores. Maybe Lirula macrospora? Best regards Steffen

Camaropella ?

<div>Hi all,</div> <div>I recently found what I think is a Camaropella sp. in New York City. The substrate is a decorticated branch of very wet wood. It may be Pinus. Immersed perithecia emerging in a cushion-like stroma. There is white material between the ostioles. There is a yellow staining to the wood associated with this pyreno. Asci IKI-, 50-64 x 5-6µm, the spore bearing part 30-39µm. The spores are ellipsoid, light brown, with two guttules, 5-7 x 2.5-3µm, no visible septa, but there IS what appears to be a germ pore at one end. Perhaps this is Camaropella pugillus. I was not certain if the yellow staining to the wood indicated Camaropella lutea, since the material surrounding the ostioles is white, not yellow.</div> <div>Any help would be wonderful.</div> <div>Thanks,</div> <div>Ethan</div>

Helvella semiobruta or helvellula?

Hi, I found a few specimens of a small Helvella under a small Cistus creticus and close to Pistacia lentiscus at Wardija, Malta. No large trees were in the vicinity. The specimens measure 18-20mm x 20-25mm. Asci were about 280-285µm x 19-21µm, J-ve and biseptate, Paraphyses slightly inflated with 6-7µm at the tips, Spores with large central oil drop 19.3-22.2 x 12.5-14.1µm; Q = 1.40 - 1.67, Mean = 20.8 x 13.4 µm ; Qe = 1.5 This species appears to be associated with Cistus as the specimens were close to the roots. I had found some similar specimens in a different location some time back but there were no Cistus or Pistacia but Olive trees, conifers and Pinus halapensis. Is this specimen H. semiobruta or H. helvellula?

Le document de Ouellette & Pirozynski m'amènerait à Tympanis confusa, mais l'hôte cité dans ce document est Pinus. Avez-vous un avis ? T.confusa vient-il aussi sur Abies ? Michel

Polysporous black discomycete

<div>Hello all, </div> <div>I was in California and found this small black polysporous asco. Macroscopically it looks quite a bit like Patellaria atrata, though the apothecia are a little bit smaller. It has bitunicate asci with (estimating) 32, or maybe 64 ascospores inside? The ascospores are small, hyaline, fusiform-ellipsoid, measuring 3-4 x 1.5µm. Asci IKI-. The dark (glutinous?) material among the asci and paraphyses does not dissipate in KOH. Is it lichenized? I'm not sure. Any help would be appreciated.</div> <div>Thank you, </div> <div>Ethan</div>

Parásito de Cribraria

Hola. Se trata de un hongo anamorfo que parasitaba unos ejemplares de Cribraria cancellata, localizados sobre un tronco de Pinus pinaster. Hifas conidiógenas con ramificaciones en ángulo recto, septos simples y una anchura entre 1,7 a 3 micras. Conidios estre esféricos y ovoides, hialinos con unas medidas de: (3) 3.1 - 4.2 (4.5) × (2.9) 3 - 3.6 (4) µm Q = 1 - 1.2 (1.3) ; N = 30 Me = 3.6 × 3.3 µm ; Qe = 1.1 Soy consciente de la dificultad que entraña el identificar cosas como esta, pero por probar que no quede. Cualquier opinión por vuestra parte aunque tan solo sea por acercarme a un género será bien recibida. Muchas gracias de antemano. Saludos cordiales.

Naemacyclus

Tamaño de 1-1,5 x 0,5 mm, sobre acículas muertas de Pinus pinaster, levantando la corteza y formando dos barreras paralelas longitudinales. Esporas muy largas, de 157 x 4,4 micras, con 2 septos en la parte central y dos apéndices en forma de punta de lanza en los extremos. Ascas octospóricas, esporas dispuestas en espiral, IKI -. Paráfisis muy septadas, estranguladas en los septos de la base y muy ramificadas en las puntas (2-4 ramas). Excípulo compuesto por cadenas de células globosas-elipsoidales. Lo más parecido que encuentro es Naemacyclus minor, con esporas mucho más pequeñas y sin los apéndices de los extremos. Sporal measurement (in water, 1000x) 128.4 [150.7 ; 164.1] 186.4 x 3.4 [4.2 ; 4.6] 5.4 Q = 25.9 [33.8 ; 38.5] 46.4 ; N = 19 ; C = 95% Me = 157.41 x 4.41 ; Qe = 36.16 Size of 1-1,5 x 0,5 mm, on dead needles of Pinus pinaster, raising the bark and splitting it with two parallel longitudinal scales. Very long spores, 157 x 4,4 microns, with 2 septa in the central part and two appendices with lance-top shape at the ends. Asci eight-spored, spores bundled spirally, IKI-. Paraphysis multiply septate, strangled on the base septa and very branched out in the tops (2-4 branches). Excipulum composed by chains of globular-ellipsoidal cells. The most similar species I have found is Naemacyclus minor, with smaller spores and without the appendices at the ends. Thank you Miguel Ángel Ribes

not rhytismatalean but ?lecanoralean

Last year the fungus presented in 2010: http://www.ascofrance.fr/forum?id=11408 was found again, now in Montenegro on Pinus heldreichii in a subalpine forest by Branislav Peric, with slightly larger spores but otherwise the same. We have now finished an article on it and still could not find anything that fits. Some similarities exist to Odontotrema, but that genus has an amyloid hymenium and lacks a spore sheath. I also see similarities to Exarmidium, but again no spore sheath is known there and the minute apothecia tend to perithecioid and always grow on naked wood, not erumpent from bark. A sequence from apothecia (ITS, LSU) did not clarify the position of this species, though the closest match was members of Lecanoromycetes (Umbilicaria, Porpidia, Xylographa). For sure, our fungus is not lichenised, but such interrelationships occur perhaps not too rarely. Zotto

Once again on needles

These grow on Pinus needles and are 0,5-1 mm wide and perhaps representatives of some Rhytismatales species.

Some Ascobolus ?

Found at 28-11-13, Attica Greece, in sandy soil, forest with Pinus halepensis and Pistacia lentiscus, dimensions 0,5-0,8 cm. Spores dimensions 20-23,5 x 11-13,5 ?m.

Geoglosum sp.

Il poussait dans une zone herbeuse dans une forêt de pins côtière de Pinus pinea à côté de Pistacia lentiscus. Je joins une photo macro et quelques micro (spores et apex de paraphyse). Toutes les spores ont 7 septa. Ce qui me décourage, c'est le sommet des paraphyses qui ont une forme étrange. Ils ont des bosses comme un "club de golf" mais très exagérées. Voyons ce que vous pensez. Salutations et merci

Yannick Mourgues, 03-02-2008

Lachnum sp.

Bonsoir. Voilà un Lachnum qui me pose problème, car rien de ce que j'ai dans ma clé ne correspond vraiment. Il y a toujours quelque chose qui ne va pas : largeur des spores, des paraphyses ... C'est sans doute une espèce facile, mais je vous la soumets quand même car je suis bloqué. Cela m'aidera à voir ce que j'ai loupé, et donc à progresser un peu ! Description : Très nombreuses apothécies blanc pur sur cône de Pinus sylvestris. Macro : fructifications jusqu'à 1,5 mm, cupuliformes à étalées, stipe jusqu'à 0,8 mm de haut. Hymenium lisse blanc pur. Excipulum densément couvert de poils blanc. Micro : Spores fusiformes, hyalines, non guttulées en général mais parfois avec 1 guttule, non septées, 7-9,1X2,3-2,7 um. Asques IKI+, octosporés, 52,3-58,5X4,5-5,5 um. Je n'ai pas vu de boucles. Paraphyses lancéolées, débordant les asques de 18 à 25 um, larges de 3-4 um, deux cloisons dans la moitié inférieure. Poils marginaux 90-110X5-6 um de long, hyalins, incrustés, à paroi mince, extrémité arrondie. La clé 6 (- - -) ne m'amène à rien. Je pense donc avoir loupé (bien que j'ai passé un long moment à les chercher) les boucles. Cela m'a mènerait à la clé 5 (- - +). Mais ici aussi je n'ai rien de convaincant. Lachnum pigmaeum est macroscopiquement jaunâtre. L. impudicum est à éliminer car lamicro ne convient pas du tout. Il ne reste guère que L. virgineum et subvirgineum, mais ces espèces ont des spores larges jusqu'à 2 um. Qu'en pensez-vous ??? Merci par avance. Yannick

Geopyxis alpina

Hola a todos. Subo unas fotos de una Geopyxis que encontramos este sábado pasado en talud húmedo, a unos 1060 metros de altitud, dentro de un bosque de Picea abies con algún Pinus sylvestris entremezclado, en suelo calizo. No es una zona carbónicola. Miden hasta 2 cm de diámetro y tienen un fuerte olor a cloaca o a aguas retenidas. Ascas no amiloides, operculadas, base bifurcada. Esporas de 14,5-17 x 8,9-10,5 micras, hialinas, lisas, sin gútulas, con un núcleo central. Excípulo ectal textura globulosa-angularis y el medular en textura intricata. ¿Qué les parece?. Pensé en G. alpina, G. foetida... Gracias por sus respuestas. Rubén

Lophiotrema ?

Hello everybody I have black, immersed perithecia on the cone scales of Picea orientalis. Diameter is about 0.2-0.3 mm. There is an elongated crest-like ostiolum. Spores are 12-14 x 3-3.4, hyaline, two-celled with a constriction at the septum. It seems to fit quite good to Lophiotrema boreale Math. as seen in Holm&Holm 1988. The problem is, this species seems to live on salix wood, not on conifers. I wonder whether someone has alternative ideas as to this species or knows that L. boreale is that plurivorous. Probably I'm completely wrong. Thanks in advance for any suggestions Stefan

Hamatocanthoscypha on spruce cone in Sweden

<div>Found some small white hairy discs on a spruce cone yesterday. Mixed forest by a river, cone covered by moss by a log.

Cistella acuum

With the key in Nordic Macromycetes this specimen identified as Cistella acuum, morphology seems fits well, but it was collected from pine bark (not from reported in the key needles). Bark of Pinus sylvestris, N60,893086° E68,677082°, 09.09.2012. Apthecia cupulate - stipitate, disc concave to flat, stem length near equal the disc diametre, thin, outer surface powdery from short hairs, disc smooth, whitish, translucent, 180 x 170 mk. Excipulum textura prismatica, cells cylindrical in stem and enlarged ellipsoid at disc; hairs cylindrical to clavate, 2-3 celled, end cell rough (covered by warts), 20 x 4; asci cylindrical, clamped, with amyloid pore, 23 x 4,3; paraphyses scarce, the same length as asci, with 1-2 septa at base, gradually enlarged to obtuse tip, 34 x 2,4 x 1,5, some branched at base; spores pip-shaped, 5,2 (4,7-6) x 1,8 (1,6-2,1) (Q=2,94; N=12).

Bryophilous white ascomycete

Hi again These gregarious, small (up to 0.6 mm), shortly stipitate and fully white ascomata are firmly attached to the aerial parts of bryophita that grows on Pinus wood. The material was sent to me by M. Tapia from Navarra (NE Spain). The asci are IKI negative and they have croziers (+). The ascospores are small and smooth. The paraphyses have some colorless VB's. Ectal excipulum with textura globulosa to prismatica with any gelified tissues. The margin has not differenciate hairs, only chains of cells with clavate and smooth end cells. We think perhaps this fungus is close to Pezizella muscicola Graddon, but the original diagnosis seems to be short and very incomplete.... What's your opinion Many thanks again Enrique

Hamatocanthoscypha ocellata

This cups from pine bark fitted about with description of Hamatocanthoscypha ocellata described in Huhtinen (1990). It differs from H. laricionis in broad, biguttulate spores (elliptic), shape of hairs and some other characters. The species reported as being specialised to coniferous bark. Collected from bark of Pinus sylvestris, 09.09.2012, N60,893086° E68,677082°. Apothecia cupulate, short-stipitate, whitish, disc smooth, outer surface and edge appear powdery from short hairs, near 200 x 150 mk. Excipulum textura prismatica, cells about 10 x 7 mk in mid-length of excipulum, becoming near cylindrical in stipe; hairs uncinate, with attenuated slightly curved tips, about 20 x 2,5 mk; asci cylindrical, clamped, about 30 x 5 mk, with amyloid pore; spores elliptical to obovate, with two round guttules, 5,8 (4,9-7,3) x 2,4 (2-2,7); paraphyses the same length as asci, cylindrical, with 1-2 septa at base, 2 mk broad, occasionally encrusted.

Claussenomyces sp.?

I found what I think might be a species of Claussenomyces with its Dendrostilbella synnematous anamorph on wet, very well-rotted Tsuga canadensis in Fahnestock State Park, New York on July 3, 2017. The largest of the discomycetous fruiting bodies in the first image is 3mm. They are gelatinous. The synnemata are about 3mm tall, coated in a green slime that evaporates/disappears very quickly as they are exposed to air/light. I find the synnemata several times a year, year-round, always on well-rotted, wet wood of all sorts: Betula sp., Fagus grandifolia, Quercus sp., Pinus strobus, Tsuga canadensis, but have never seen the associated discomycete until this one. We were unable to find loose spores in the Claussenomyces-like fruiting bodies, only seeing them in a single ascus. They were small, about 2x3 microns and they appear to not be septate. Am I on the right track? Might they be something else? Any suggestions/guidance be would be most welcome! Thanks, Tom

Unusual cupulate coelomycete on Scots Pine needle litter

Dear friends, I have recently found a cupulate coelomycete on Pinus sylvetris (Scots Pine) needle litter in Wales. It has conidiomata which are immersed at the base and are pale brown and collapse on drying (50-250um wide), and occur in small groups or singularly. The conidiomata are flat topped with an ostiole, and a ring of dematiaceous, blunt, irregular, short 'hairs' around the rim. It produces narrow, cylindrical phialidic, conidiogenous cells on septate, sometimes slightly swollen conidiophores. Conidia are hyaline, narrowly cylindrical and non septate (approx. 19 x 1um). I have had a look at most of literature on cupulate coelos by Brian Sutton but my specimen does not correspond to anything that I have looked at. David Minter said it's not Fujimyces, Linodochium hyalinum or L. formosum, Lemalis aurea. It's not Pseudocenangium succineum. He has never seen anything like it before or never come across anything like it in the literature, unless it has been described recently. Has anyone come across this before?? Thanks, Jo

Orange mystery

Bonsoir tous I have come across this unfamiliar orange fungus; it is associated with a hyphal weft on the short 'stem' of a Pinus cone. At first glance one might suspect something nectriaceous given the colour Key features are: *globose bodies, c200µm diameter, covered with short (mostly capitate) projections *scant evidence of a surrounding wall *no asci formed *golden conidia (?) which clearly give the fungus its colour; these average 12 x 8.5µm I vae been assuming it is the anamorph of an ascomycete, but am now wondering whether it could have phycomycetous affinities any suggestions very welcome amitiés Chris

Dear forum, In the moss dunes of Bray-Dunes(F),one of my friends found some brown cupulate fruit bodies with short whitish stem. No ribs were observed. Hymenium brown. Exterior of cup much paler. Asci were 300-350µ long and IKI neg. No croziers were found. Spores were ellipsoid, 22-24x12-13µ and contained 1 large guttule and several small ones. Helvella or young Dissingia? Any help would be appreciated. Marc

Geopora clausa f. ellipsospora?

Bonsoir à tous: J'ai récolté sous Pinus pinea, Cistus albidus et Tuberaria guttata, dans sol schisteux, un seul exemplaire de Geopora. Microscopiquement va bien avec Geopora clausa f. ellipsospora, sauf parce que les spores sont bigutulées et peut-être un peu longues, mais je pense qu'il n'y a pas une autre option. Merçi d'avance par vôtre opinion. Amicalement, Tomás Illescas

Sarcoscypha macaronesica not Macaronesian?

Good night This Sarcoscypha, 1-1,5 cm diam., was found in Spain, Andalucía, Córdoba, 421 m, 24-I-2016, in small twigs, probably Viburnun tinus, in a forest with Pinus pinea, Quercus suber, Corylus avellana and Castanea sativa. Spore size and shape fits me more with S. macaronesica than S. coccinea. Is it possible? Spore measurement in water, 1000x and live: (21,4) 24 - 30,8 (33) x (9,4) 10 - 12 (13,6) µm Q = (2) 2,2 - 2,9 (3,3) ; N = 102 Me = 27 x 10,9 µm ; Qe = 2,5 Thanks a lot. Miguel Á. Ribes

Pezicula cinnamomea?

<div>Hi</div> <div>With species of this genus I always have uncertainty about the designation, of course, except for a few species that are quite characteristic. Could this be P. cinnamomea? It was growing on a dead branch in Salix. Regards Mirek</div>

Guy Buddy, 26-08-2019

Plicaria?

I was thinking this could be P. carbonaria or maybe P. trachycarpa but the spore size is too big and I would say the spores have warts, not spines. Flesh rubbery, thick, outer and inner apothecium finely roughened, pigmented. Spores round, pigmented brown, with warts, ~16.6 um. Found in Pennsylvania, USA from the forest floor in mixed Quercus, Acer, Betula, Pinus, Tsuga forest.

Calycina ?? 030619 31

Good morning On 3/6/2019 we find at Tenerife (Canary Islands), on a very very rooten wood, a lot of very small white crowdly apos. At the beginning we thought in Strossmayeria basitricha, but micro said no. White apos, pulvinate, crodly, irregular margin, (173,3) 174,6 - 266,3 (309) × (133,9) 137,9 - 171,7 (175,2) µm; N = 18; Me = 226,8 × 154,3 µm.

Orbilia on pine

Dear all, I collected the samples from the wood of a fallen pine (Pinus pinaster) in Serra de Sintra, Portugal. It seems to me that the specimens were immature, since I was not able to see any spores. I made the microscopy using cotton blue in lactic acid and saw the asci and paraphyses. However, I also observed some roundish balls that I could not identify (center of the photo). Is it possible to say anything valuable about the species? Thanks in adance, zaca

White hairy on Angelica

The worst frost nights are now over here in southern Finland (since 48 hours) so more and more fungi are showing up. Here a very young white disco growing on a last year's stem of Angelica ?sylvestris. The diameter of the apos is about 350 µm and the hairs above 200 µm. I observed just a few ejected spores measuring on average 8,5 x 1,6 µm but I am trying to get more. In the mean time I'd be happy for ideas on what it could be.

Proliferodiscus sp.?

Hello everybody, I hope somebody can help me with this Proliferodiscus (?) species. Ecology: I found it on brightly reddish colored parts of a decaying Basidiomycete (The polypore Antrodia serialis) on a Pinus log. Macro: Apothecia up to approx. 0.8 mm, disc light brown, margin white, excipulum brownish towards the base. Micro: Asci 40-55 x 5-7 ?m, pleurorhynch, Porus reddish grey in IKI, blue in IKI after KOH treatment. Paraphyses cylindric, 1.5-2 ?m diameter. Spores ellipsoid, with two small drops at each end, often somewhat asymmetric, 6-7 x 2.0-2.6 ?m. Hairs cylindric, 2.5-3.5 ?m diameter, covered with spinulose cristals, frequently septate, distal part mostly < 30 ?m. The hyphae that form the hairs are continuously getting shorter septate, distinctly thick walled and brownish towards the base, forming a textura prismatica. There are no distinct colour reactions of the hairs or excipulum (sometimes partly pinkish in KOH). Thanks for any help, Stefan

Ascas amiloides, pleurorrincas. Creo que es típico de Vibrissea flavovirens la formación de esporas con 15 septos y que se fracturan en 4 trozos con 3 septos cada uno. De esta recolecta me hace dudar su pequeño tamaño y también el hábitat, ya que yo siempre las he localizado sobre madera de fagus.

Petit disco poilu

Bonjour, Un tout petit discomycète sur écorce de Pinus pinaster : Cupules stipitées, 0,2-0,3 mm de diamètre, hyménium grisâtre hygrophane Spores (8) 12-16 x 2 µm de forme effilée, hyalines, non septées, guttulées sauf au centre. Asques 35 x 6 µm, octosporés, apparemment sans crochet, petit appareil apical amyloïde (MLZ sans prétraitement). IKI non testé (je dois en commander). Paraphyses hyalines, 2 µm de diamètre, peu nombreuses et peu visibles. Poils mesurant jusqu'à 90 x 5 µm, gris foncé à paroi épaisse, pointus et non septés, peu/pas renflés à la base non fourchue. Excipulum en textura angularis de 5-10 µm Je ne sais pas de quoi le rapprocher...La macro fait penser à un mini Torrendiella mais le petit appareil apical tout plat (environ 2 x 1 µm) ne colle pas, et aucune espèce du genre n'a de spores aussi étroites. Qu'en dites-vous ? Pascal

Peziza muscicola or berthetiana?

Hi, I have a few collections of a black Peziza from the same area collected over the last 2 years. For now I am presenting this specimen which has some characteristic of P. muscicola. The specimens were collected (10/1/15) amongst mosses in an area with Pinus halapensis, at Verdala Buskett, Malta. The collected material was 15-30 x 14-23mm, hymenium dark black, inner surface smooth sometimes pitted. No latex was observed on cutting or breaking. Asci J+ve, biseptate. Paraphyses slightly inflated, septate. Spore are biguttulate at the polar ends, very rough with ?ridges, reticulum, warts - after staining with lactophenol CB. Size (11.5) 12.8 - 16.8 (17.3) x (7.4) 8.1 - 9 (9.2)µm Q = (1.3) 1.4 - 1.9 (2); Me = 14.6 x 8.7 µm ; Qe = 1.7. Other collections show slightly larger spores up to 18µm in lenght. What is your opinion?

Peziza sp (Látex azul)

Hola a todos/as Adjunto fotos de un Peziza recolectada en el sur de España, en una plantación de pinos ( Pinus pinea) y encinas (Quercus ilex) en suelo arenoso- calcáreo, crecían en el suelo muy cerca de una antigua hoguera. Apotecio de hasta 3cm de diámetro aprox, himenio de color violeta oscuro, parte externa pardo-amarillento, furfurácea, al corte el contexto presenta color amarillento y segrega látex de color azul . Al micro destacar las esporas ornamentadas con verrugas, algunas conectadas formando pequeñas placas, de: 17,0 - 19,1 × 9,0 - 9,7 µm Ascas con la base pleurorrincas, de 334,5 - 368,0 × 14,0 - 15,2 µm Paráfisis ligueramente engrosada ( 5,0 -6,8 µm,) con pigmento intracelular de color violeta, algunas paráfisis presentan en el ápice una envoltura de color amarillenta. Excípulo medular de textura intrincada y excípulo ectal con células globosas-angularis, presenta pelos hifoides como los que muestro en el adjunto. Estoy mirando Pezizas que segreguen látex azul y ninguna me cuadra, a ver si con vuestra ayuda conseguimos identificarla. Gracias anticipadas Curro Valencia

Ayuda con unas hifas conidiógenas

Hola. Una roña hilosa por debajo de un tronco de Pinus uncinata bastante seco, a 2100 msnm. sobre unos rizomorfos negruzcos. Hifas pigmentadas y delicadamente verrucosas de color marrón, en la base de un color marrón muy oscuro y de entre 7,3 a 9,7 µm. de ancho con septos simples. Conidióforos verrucosos de color marrón claro, ramificados, mas claros al acercarse a los extremos, con septos simples y de entre 3 y 4 µm. de ancho que producen de entre 1 y 4 conidios. Conidios ovoides (redondos en vista frontal), de color marón, verrucosos y con unas muy diminutas y discretas espinas, las medidas de los conidios de: (4.7) 5.1 - 6.1 (6.5) × (3.8) 4 - 4.6 (4.9) µm Q = (1.1) 1.2 - 1.4 (1.6) ; N = 50 Me = 5.6 × 4.3 µm ; Qe = 1.3 Descarto la Calcarisporium arbuscula, que conozco perfectamente y ya he estudiado en varias ocasiones, lo mas parecido que conozco estaría por Geomyces o Gliocladium, aunque con muchas dudas.

Ombrophila fagiseda ??

Hola a todos. Subo unas fotos de un asco que he encontrado hoy sobre piñas que estaban semisumergidas en un riachuelo a unos 1100 m. Miden hasta 5 mm de diámetro. Ascas con croziers en la base, IKI+, uniseriadas o biseriadas. Esporas de 11,5-14 x 4-5 micras, medidas de esporas recién expulsadas del asca mientras miraba otras extructuras. Me parece que tiene extructura de gel también en el exterior del apotecio. Células exterior cerca del margen en forma de pera y con un extremo muy largo. He visto Ombrophila fagiseda que se parece, aunque la mía está sobre piñas. ¿Qué les parece? Gracias por su ayuda Rubén

asco conchiliforme

Bonjour, Je suis retourné à la pêche aux moules... sur picea : un asco conchiliforme. Ce que je peux dire c'est que je n'ai pas affaire à un Mytilinidion, ni à Byssolophis sphaerioides.Je ne sais pas à quoi ressemblent les éléments micros de Lophium mytilinum alors si quelqu'un peut me guider. Avec des spores de 2µ de large et une longueur dépassant 40µ je me serais dirigé vers d'autres genres (ex. glyphium) mais la macro ne colle pas. Alors quelqu'un peut-il m'aider ?

Claussenomyces atrovirens?

<div>Hi!</div> <div>Black (when dry), solitary or somewhat clustered, sessile to very short-stipitate apothecia on dead, decorticated branch of Pinus sylvetris, Central Norway.</div> <div>Asci 75-125 x 12-18 microns (in water), IKI-. Asci mostly with granular contents, but a few beginning to form septate spore, difficult to measure presicely. Paraphyses agglutinated in a greenish/olivaceus matrix (resinous material?), apparently with transverse, elongate "bodies". Subhymenium brownish.</div> <div>I wonder if Claussenomyces atrovirens can be this dark when it dries. Is Patellaria atrata an option?</div>

Hymenoscyphus aff. fulvidulus

Bonjour. Je vous soumets cette récolte effectuée en Corse, sur cône mort de Pinus nigra ssp. laricio. Apothécies courtement stipitées, Ø 1-3 mm, à hyménium jaune-beige, rougissant dans les blessures ; surface externe concolore, glabre. Asques sans crochet, 75-92 x 7-8 µm, anneau apical IKI+ (bb). Paraphyses emplies de VBs. Spores elliptiques allongées ou ± ciboroïdes, 12-18 x 3,8-4,2 (4,5) µm, guttulées, avec une cloison sur les spores les plus mûres (hors asque). Excipulum médullaire de textura intricata ; excipulum ectal de textura angularis, mêlé de cellules plus allongées, dont certaines contiennent des VBs. Il me semble que l'espèce la plus proche serait H. fulvidulus (= Pachydisca fulvidula) mais la teinte semble plus pâle, les spores plus petites, avec une guttulation moins importante. Qu'en pensez-vous ?

Hymenoscyphus "calycinoides" ?

Hello! I have collected these specimens on woody drebis-woody sp, stripped of bark, semi-submerged in water. The specimens look like and match well with Hymenoscyphus "calycinoides" if I m not mistaken, Baral has it under study. If I could get some information about it that would be great and welcome. Any help is welcome. Thanks you very much! Apothecia: Withe, somewhat traslucent , disc-shape. Ascospores: 11-18 X 4-5 µm , with a septum, when inside the asci and outside. Hyaline and almost always with two small guttules. IKI + not very pronounced. Paraphyses: Cylindrical, hyaline and at the apex with some lipid content. IKI -. Thanks you!

Marcelleina benkertii?

Hello, on the verge of Christmas eve first I wish everyone merry Christmas and a peaceful New Year! A friend found these violet to deep purple ascomycetes this November on loamy soil, with moss and with Pinus and Betula (mostly) in the Netherlands. Apothecia were flattened, with rugulose hymenium, paler and smoother on the outer surface. They were about 8 mm. At first she thought of S. planchonis, but because of the purplish colouring of paraphyses and excipulum and the one big guttule in the smooth spores I think it's M. benkertii. All the features and measurements fit the descriptions (Moravec and others), except that I didn't see any forked paraphyses. There is dried material and material in CTAB. My questions are: Do you think my idea is correct? Does anyone know if there is type-material so that it can be sequenced? It would be the first record in the Netherlands. Thank you!!

Calycina conorum ?

Hello, this seems to be very close to Calycina conorum, except that I found different data about amyloidity too (IKI+red in M.Hairaud's article or on asco-sonnenberg.de web). Is there some variability like in Lachnellula? Or is this another species? (I don't think my Lugol is diluted - it's only half year old and on some Lachnellula sp. on the same day showed the red reaction very well.) Thank you for your opinions. Viktorie On cones of Pinus cf. nigra (long needles, probably planted trees near a cottage), Slovakia, 1.IV.2018. Apothecia sessile, less than 1 mm wide, white to yellowish, oxidating to wine red.

.. collected at 5.8.2018 in the Nature Reserve "Hochschachten" at about 1150 m NN, on a lying piece of wood (bark) likely of Pinus in bog vegetation (acid, dystrophic). The apothecia were about 3-4 mm large, the spores are about 13-17/5,5-6,3 µm large. Distinct hairs are absent, the paraphyses quite filiform. Can somebody provide me with a hint? Best regards, Lothar

Ciliolarina neglecta ou...

Un petit asco sur bois décortiqué de pin. J'étais partie pour un hymenoscyphus, mais les spores ne correspondent pas.Les asques mesurés après dissociation ne dépassent pas 30 µ. Qu'en pensez vous ?

Adonis

Hi, I need help On the leaf of Adonis vernalis (Serbia). Macroscopically, it looks like Ophioceras leptosporum, but I didn't find any spores, only these conidias (?). Thanks Dragiša

Plectania rhytidia?

Good evening! My friend Matthias Theiss found a beautiful Plectania in Portugal, 15.04.2008, Lago de Albufeira, near Lissabon. The diameter of the ascocarps was 1 cm. Substrate were twigs of Eucalyptus lying on a slope at an artificial lake. The soil was sandy and covered with a forest of Pinus pinea and Eucalyptus, there were different kinds of fern and Arum. Accompanying fungi were Arachnopeziza aurelia, Phellinus pini, Pisolithus arrhizos, Laccaria tortilis. I enclose a foto and a foto of the spores. What do you think, is it Plectania rhytidia? Thank you for your opinion Hermine

Coniochaeta ?

Bonsoir, Je me demandais si cet asco noir poilu trouvé sur Pinus pouvait appartenir au genre Coniochaeta que je ne connais pas trop. Les poils bien pointus ne dépassent pas 50µm de long. Asques octosporés unituniqués d'environ 100 x 12 µm donnant des spores brunes subglobuleuses d'environ 11 µm de diamètre moyen. Parfois un sillon observé sur celles-ci. Coniochaeta malacotricha ?

¿Parascutellinia?

Hola a todos. Tengo estos hongos que recogí en una zona arenosa con mucha humedad, bajo Pinus radiata. Microscópicamente creo que me encaja bien con Parascutellinia violacea, pero el color de los apotecios no me encaja. ¿podría ser simplemente esta especie con poca pigmentación? Gracias. Apotecios hasta de 2 mm, solitarios o en pequeños grupos, sésiles, urceolados en un principio y algo aplanados después, con el exterior de color marrón, cubierto de pelos, e himenio grisáceo. Escípulo ectal formado por células de textura globuloso-angular, marrones en zona externa e hialinas en su zona más interna. Escípulo medular formado por células hialinas, alargadas, de textura intricata. Pelos hasta de 200 µm, marrones, de paredes gruesas, algo engrosados en el centro, con 0-2 septos. Ascas de (268,86) 286,85 - 343,54 (344,68) x (18,79) 19,04 - 24,26 (24,53) µm; cilíndricas, operculadas, octospóricas, no amiloides, con croziers en la base. Ascosporas de (19,48) 20,47 - 23,10 (23,86) x (10,60) 11,52 - 12,41 (12,77) µm; Me = 21,68 x 11,95 µm ; Qe = 1,82, uniseriadas, aparentemente lisas en agua, pero finamente verrucosas al utilizar colorante, hialinas, con dos grandes gútulas en su interior, acompañadas de otras menores. Paráfisis ramificadas en la base, septadas, con el ápice algo engrosado. Saludos. Salvador.

Mollisia ? Tapesia ?

Un autre dans les Dermataceae cette fois. GC13042106 Très abondant à la base de tiges mortes d'Angelica sylvestris. Un subiculum noir semble présent occasionnellement (voir photo ascomes avec ou sans). Apothécies cupuliformes, 0,4-1 mm, en troupes denses, sessiles, à hyménium gris foncé et marge blanchâtre fortement incurvée. Spores 7,9-10,2 x 1,8-2,4 µm, fusiformes, à très faibles et petites gouttes polaires. Asques environ 55 x 6 µm, bisériés, bouclés, I+ (lugol). Paraphyses cylindriques, non réactives dans KOH 5%. Excipulum à textura prismatica, puis excipulum ectal à textura globulosa, fortement pigmenté de brun foncé. Avec quelle biblio pourrais-je tenter de déterminer ce champignon ? Merci !

Gyromitra esculenta??? en pinar de peridotitas

Hola colegas Me gustaría contar con vuestra opinión sobre esta Gyromitra. Son pequeñas, no superando los 4 o 5 cm de diámetro, templanas recolectadas el 8 de marzo con las esporas completamente maduras, en un pinar de pinos resineros (Pinus pinaster), en suelo de peridotitas, en el sur de España. Por el tamaño y por la mitra poco lobulada se asemeja a G. tasmanica, pero las ascosporas son muy grandes, (23.2) 24.1 - 28.9 (30.4) × (11.8) 11.9 - 13.2 (13.6) µm Q = (1.8) 1.9 - 2.2 (2.5) ; N = 30 Me = 26.2 × 12.6 µm ; Qe = 2.1 Las esporas parecen presentar finas granulaciones no cianofilas. Ascos de: (354.7) 405.1 - 487.1 (505.5) × (15.1) 15.9 - 18.5 (19.4) µm. Son Gyromytra esculenta sin lugar a dudas??? No estoy seguro de esto.... Que pensáis..... Un saludo a todos Curro Valencia

brown Peziza from Norway

... collected at 20.6.2015 in the National Park of Dovrefjell - wayside on the ground unter Betula and Pinus. The year 2015 had a very long winter, and so it would be possible that "snow fungi" are present, as the most common fungus we found at this journey was Gyromitra esculenta (atypically late). I have some problems with characters and so am not sure about possible results. Fist: The spores (they measure about 18-19,5/8,5-9,5 µm) seem to be minutely ornamented to me, finely punctate. It is difficult to bring this "onto the foto" - and there seems to be little staining with CB. Anyway, a trace of ornament ist present as I think. Second: I am not really sure about the structure of the excipulum. Behind (under) a layer of quite large cells there is a layer that I can only difficultly interpret if it is a "middle textura intricata" or not. So - as there are a lot of brownish Pezizas I have no security about possible determinations. I imagine P. pseudovesiculosa (but the apothecia were not too large), P. ninguis (I do not find the paraphyses to be monliniform) - or perhaps P. granulosa if I consider the spores to be smooth. Can somebody provide me with a hint. Best regards, Lothar P.S. The first microfoto was taken after the find, the rest today

¿Hyaloscypha?

Hola. Unos diminutos apotecios fotografiados el pasado domingo sobre un tronco de Pinus sp. quemado. De color blanco, sesiles, con forma de disco con el borde irregular de tan solo entre 0,10 a 0,25 mm. Células marginales a modo de pelos poco evidentes, sin incrustaciones observadas e inamiloides al Melzer. Ascos octospóricos con unas medidas de (26.5) 29.7 - 36.1 (40.2) × (3.9) 4.6 - 6 (6.3) µm., con una media de Me = 32.3 × 5.2 µm. al parecer con uncínulos en su base y reacción amiloide del muy diminuto aparato apical. Paráfisis filiformes, algunas bifurcadas, con contenido en su interior y sobresaliendo por encima del nivel de los ascos, con una anchura de entre 1,5 y 2,5 µm. Ascosporas de pared fina, entre cilíndricas y fusiformes, con los extremos algo apuntados, con contenido de aceite en su interior y unas medidas de: (4.6) 5.2 - 6.8 (7.2) × (1.5) 1.7 - 2.4 (2.7) µm Q = (2.2) 2.4 - 3.5 (3.8) ; N = 50 Me = 5.9 × 2.1 µm ; Qe = 2.9 Atendiendo a sus características pienso en una Hyaloscypha, por el sustrato hasta Hyaloscypha aureliella, especie muy abundante que me encuentro a menudo pero que tiene unas medidas de los apotecios muy por encima y unos pelos marginales evidentes y con incrustaciones. Cualquier propuesta por vuestra parte será bienvenida. Muchas gracias de antemano. Saludos cordiales y Feliz 2022

Calycina 260119 on Alnus

Good night A friend brings me this species growing on Alnus wood Asci are small, 8-spores, with croziers, IKI +, (23,8) 24,1 - 32,5 (36,1) × (3,3) 3,5 - 5 (5,5) µm; N = 22; Me = 28,7 × 4,3 µm Spores are very small too, with 2 gutules, de (4,6) 4,8 - 6,6 (7,1) × (1,5) 1,6 - 2 (2,1) µm; Q = (2,4) 2,6 - 3,6 (4); N = 54; Me = 5,5 × 1,8 µm; Qe = 3,1 Paraphysis are very width compared with asci, completly full with very big VB. I have never seen this before. Ectal excipulum have textura prismatica, with big VB in the external layer and at the margin. Medular excipulum have textura intricata. The nearest species I find is Calycina guttulifera, but I see this species RB and BB. Thank you.

Acanthostigma cf. scopulum from Fagus wood

Dear Friends Today, during the review of other specimens from the Carpathians, I found Acanthostigma sp. sample (unfortunately, slightly immature). I think it can be Acanthostigma scopulum Peck. I am never seen this species earlier, therefore I can not be sure. Do you familiar with this species? Grateful before, Alex

Plectania milleri 130422

Buenos días El otro día me trajeron estas Plectania de 4-6 x 1-1,5 cm de un bosque mixto de Pinus y Quercus, separadas entre ellas por unos 100 m, saliendo en zona donde predominaba el Quercus y no había Pinus cerca. El borde es festoneado, el exterior está cubierta por una densa malla de pelos marrones-negruzcos, sobre todo en la base, no tiene látex. El excípulo ectal tiene textura subglobulosa-angularis, de células oscuras, marrones, con numerosos pelos marrones, largos, sinuosos, septados. El excípulo medular tiene textura intricata, de color claro, no se aprecia que sea gelatinoso. En su interior se aprecia de forma dispersa algo parecido a los pelos externos o pequeñas manchas marrones en las hifas, que recuerdan vagamente a los "finger-prints" de Otidea bufonia. No son abundantes como los señalados en "Contribution to the knowledge of Plectania milleri, a Northwestern American species" de Carbone, Agnello y Harnisch, pero sí están presentes. El subhimenio tiene textura intricata, de color claro. Las ascas son muy largas, octospóricas, uniseriadas, IKI -, con la base en zig-zag y en ocasiones bifurcadas, de (344) 370,9 - 458,3 (494) × (10) 11,6 - 14,9 (15,9) µm; N = 27; Me = 418,8 × 13,1 µm. Las paráfisis son de 2 tipos: unas estrechas cilíndricas y ramificadas en el ápice y con forma de cuerno; otras más gruesas, no ramificadas y con paredes más gruesas, en ocasiones más coloreadas, que podríamos llamar "setas". Las esporas son elipsoidales, bastante alargadas, lisas, en ocasiones con una cobertura gelatinosa en los laterales (no se han apreciado en los polos), y con 4 núcleos, de (22,3) 23,4 - 26,8 (29,4) × (9,2) 9,6 - 11,2 (12,1) µm; Q = (2) 2,1 - 2,7 (3,2); N = 61; Me = 25 × 10,5 µm; Qe = 2,4. Con estos datos, viendo el artículo anteriormente citado, sólo llego a Plectania milleri, especie conocida únicamente en Estados Unidos. Aunque hay algunas discrepancias con lo citado en el artículo mencionado (el subhimenio es claro, el excípulo medular no es gelatinoso y no se menciona que las esporas tengan 4 núcleos) quizá se deban al estudio de material seco frente a este nuestro en vivo. Gracias por vuestra opinión. Miguel Á. Ribes

Marcelleina benquertii?

Hola a tod@s Estas supuesta Marcelleina están recolectadas en un talud de un camino forestal de bosque mixto de Pinus sp, Abies pinsapo, matorral mediterráneo y suelo calizo, en Ronda (Sur de España). Ascomas de hasta 6mm, discoideos, de color violáceo oscuro, sésil, parte externa concolor. Esporas esféricas, lisas, con una gran gutula. De: 12,0 [12,7 ; 13,0] 13,7 × 11,8 [12,6 ; 12,9] 13,6 µm Q = 1,0 [1,01 ; 1,0] ; N = 32 ; C = 95% Me = 12,9 × 12,7 µm ; Qe = 1,0 Ascas octospóricas, no amiloide, con croziers De: 232,1 [267,5 ; 300,3] 335,7 × 12,9 [15,0 ; 16,9] 19,0 µm Paráfisis ensanchadas en el ápice, con una capa gelificada de color marrón amarillento en lo alto y pequeñas vacuolas en su interior (muy pocas). Excípulo medular y ectal de textura angularis, hacia el margen con células clavadas. Marcellin benkertii es muy similar, consultando Revision Of The Genus Marcelleina (Jerí Moravec) solo difiere el tamaño de las esporas y las ascas, que es algo menor, también en otras descripciones (Miguel Angel Ribes, Ascofrance),(Mibovalleroveto.it) sobre esta especie reflejan esporas algo más pequeñas y apotecios copulados , por lo demás parece que encaja bastante bien. Que pensáis?? Saludos a todos Curro Valencia

Lachnellula with long spores - L. pseudofarinacea L. ellisiana?

Hello all, About a week and a half ago in a cemetery in Brooklyn NY I found what I believe is a Lachnellula on the bark of Pinus flexilis. The apothecia are tiny, with a yellow hymenium clothed in white hairs. The hairs are septate, tapering, smooth or minutely punctate. Paraphyses extend well beyond the asci and taper to an almost acute point. They appear to contain oil droplets. Asci are 61-72 x 6-7µm, IKI+, croziers+ (please correct me if I am wrong). Spores are long with acute ends, 15-43 x 2-4µm. The spores might range somewhat longer than my measurements—in looking back over my photos I see what may be broken spores that I ignored because I thought they were broken paraphyses. (see the last photo) I will probably have to return to the place of collection and look again to get more details about the hairs and the true spore measurements. But maybe someone can point me in the right direction with the limited information I have presented here? Thanks, Ethan

Ayuna con una Nectriaceae

Hola. Una aparente Nectriaceae compartiendo espacio con algunos ejemplares de Vibrissea flavovirens, aunque no creo que tenga ninguna relación con ella, sobre la superficie de un cono bastante degradado de Pinus mugo y semisumergido en agua limpia procedente del deshielo, en el Pirineo Catalán y a 1850 metros sobre el nivel del mar. Muy diminutos peritecios, más o menos globosos con un mamelón en su parte alta, de un llamativo color rojo, brotando de manera dispersa y con un diámetro de tan solo entre 0,19 a 0,37 mm. Pared del peritecio formado por hifas filamentosas fuertemente entrelazadas entre si, con abundante pigmento intracelular anaranjado que se vuelve violáceo con el KOH al 20%. Ascos octospóricos, uniseriados con una longitud de entre 100 y 115 micras y una anchura de entre 6,2 a 7,9 micras. Aparentemente no se observan paráfisis. Ascosporas de pared aparentemente lisa, con un septo central en el que se observa un sutíl constreñimiento, y contenido granuloso en su interior con unas medidas de: (13.7) 14.4 - 17 (17.4) × (5) 5.7 - 6.6 (6.9) µm Q = (2.1) 2.3 - 2.8 (3.1) ; N = 36 Me = 15.7 × 6.2 µm ; Qe = 2.6 Soy plenamente consciente de la dificultad que representa el identificar estas especies sin disponer de una imágen de la sección del peritecio, punto que me ha sido del todo imposibe dado el muy pequeño tamaño de los ejemplares. Cualquier opinión por vuestra parte será bien recibida. Muchas grcaias de antemano. Saludos cordiales.

Dead and dry inoperculate hemiamyloid 100318

Hi friends I studied this dry and dead inoperculate and hemiamyloid cup-shape fung, about 1 cm of diameter. Collected on 10/3/2018, at floor with needles of Pinus. Asci cylindrical, 8-spored, hemiamyloid and with croziers. Spores cylindrical to slightly alantoid, without LBs (dead state), (7,9) 8,7 - 10,6 (11,3) × (2,8) 3,1 - 3,7 (3,9) µm; Q = (2,2) 2,5 - 3,1 (3,8); N = 39; Me = 9,5 × 3,4 µm; Qe = 2,8. Spore edge looks like dextrinoid, it is slightly red, similar to spores of Ombrophila hemiamiloidea. Paraphysis cylindrical without VBs. Ectal excipulum with textura gelatinosa. Medullar excipulum with a textura mixed between angularis in the upper and prismatical in the lower part. Thank you.

Ascotremella faginea?

Hi forum, Could this eventually be Ascotremella faginea? A was unable to find mature asci with spores. Alternatively this could be Exidia recisa, but I was also unable to find globose basidia. Spores shown are probably contaminant. There were only 12 of them found after long searching and could be easily from somewhere else. Sorry for poor microscopy of surface of sporocarps. Can it help at all?

aff. "Hymenoscyphus resinae-piceae" on wood of Picea

.. on a standing, dead log with thousands of fruitbodies, found 11.8. in the Bavarian Forest. The white, stalked apothecia are downy. Excipulum prismatica, with end-cells finely rough-warty, partly brown Asci about 30-35/5-6 µm, IKI+ euamyloid with Calycina-type, often at the base with long-cylindrical refracting content, with croziers Spores about 4,5-7/1,7-2,5 µm, mostly with two guttules, somewhat fusoid Paraphyses not very conspicuous - in IKI with brown guttules (also in excipulum cells) Deep in my mind I had the name Calycina resinae-piceae (I think Zotto once determined a find of mine with this?) and in ascofrance I found this: <a href="1229/small-asco-on-the-inner-surface-of-pinus-radiata-wood">http://www.ascofrance.fr/forum/1229/small-asco-on-the-inner-surface-of-pinus-radiata-wood</a> The spores are almost the same appearance as mine - and I think I am not too far away ... Can somebody help? Best regards from Lothar (still working in the Bavarian forest)

On Abies needles

Good evening, in spring I found these small ascomycetes on Abies alba needles. The biggest ones measured about 1 mm in diameter. I though it could be Cistella acuum, but everything is too long in my fungus - spores are 5 - 8 x 1 - 1,5 µm, asci 40 - 44 x 3 - 4 µm, hairs up to 105 x 2,5 µm. The inner ring is blue in Melzer. The hairs are covered with granules. The other possibility I considered was Dasyscyphella pulverulenta, but my fungi lack the yellow resin and the shape of spores is a little bit different in comparison with this picture: http://www.ascofrance.com/forum/15317/cistella-dasyscyphella? Locality: Czech republic, Moravia, Dlouhá Loucka Date: 13th April 2013 Would someone have a tip? Thanks a lot, Zuzana

Helvella verruculosa ?

Hi everyone, This specimen was collected in the beginning of February at Parque de Monsanto, Lisboa. Its macro appearance indicated me something like Helvella leucomelaena. However, doing the microscopy, it is clear that this can't be, since the spores are not smooth having a clear reticulate pattern already noticed while looking at the hymenium. Using the keys available at Refs. 1 & 2, I find no alternative. Only looking at Ref. 3 I realize the existence of a species with similar features, Helvella verruculosa (=H. dryadophila). Is it possible? Thanks in advance, zaca Ascospores dimensions: (15.7) 16.3 - 18.3 (19.2) × (8.9) 9.4 - 11.6 (12.7) µm Q = (1.4) 1.5 - 1.76 (1.8) ; N = 56 Me = 17.2 × 10.5 µm ; Qe = 1.6 Asci up to 280 x 16 um Paraphyses dark brow pigmented, up to 7 um wide at apex.

Lachnellula subtilissima, but not quite!?

Recently found a gergarious group of what appears to be a Lachnellula species on probably a fallen Pinus branch. All looks reasonable for L. subtilissima except some paraphyses have 'spear-headed' tips or spathulate-lanceolate ends. Some are rounded cylindrical as perhaps expected. The other question relates to the hairs where some seem to have crystals forming at their tips. Some rounded some blunt ended. Marginal hairs white at first soon changing to yellow. Any help would be very much apprecaited. Full description in the attched file:

Hymenoscyphuses? on cones

Hello, yesterday evening I decided to go and pick those Hymenoscyphuses I found on Epilobium. I'm just too curious and checked some interesting looking places on the way. So I found some Hymenoscyphus like on pinus cones and tried to find them more and ended finding different looking ones, too. It was quite late, so the photos are nothing like perfect. Here's the first one. They are about 0,5-1,5 mm wide and 1-2 mm high.

Is this Keisseriella pinicola?

Hi, Im helping to lead a long-term fugal survey of Longshaw Estate in the Peak District, Northern England. I found this tiny asco with Orbilia on rotten conifer wood - most likely Pinus. The fungi were spherical, about 0.1mm in daimeter, scattered in a small group with setae around. They had a single ostiole. Asci were approx 40 x 5 um in Lugol. Spores were multiseptate - difficult to work exactly how many septa. Size was 17-21 x 3-4 in water, smaller in Lugol. Setae were attached to the fungi, approx 4 um wide and at least 50 long. The description in Ellis and Ellis of Keissleriella pinicola looks close. It hasn't been recorded in our part of England, but is reported from Southern England to Scotland. Any help with this ID would be much appreciated, Steve

Blackening ascomycet

Hi, at New Year's Day I found this very strange ascomycet which I cannot determine. What a good start for this year... It grew in the marginal area of a swamp on a rotten, very mossy tree stump. I am not even sure about the genus. The most striking characters are the blackening apothecia and the IKI- asci. Here is the description: Apothecia: White, soon conspicuously blackening (whole fungus, especially the stipe and the stipe base) or turning dirty yellowish, 3-12 mm high, head 1-3.5 mm ø, head on the underside smooth or, when older, rugose. Stipe smooth or a bit hairy-rugose. Spores: irregularly elliptic, elliptic, often flattened on one side, partly deformed and with a smaller end, also comma-shaped or rhomboid, with 0-2(3) septa, occasionally germinating, sometimes with a visible nucleus, alive with hardly any content, 20-25 x 5-6(8) µm. Immature spores in asci nearly spherical! Asci: 8 spored, clavate, biseriate, IKI-, Melzer's reagent-, KOH 5% + Melzer's reagent-; however, there is an apical apparatus, croziers+, (107)120-130 x (8)12-14 µm. Dead asci (observed in Melzer's reagent) have an up to 3 µm high dome. Paraphyses: filiform to slightly clavate, with strongly refractive, hyalin, multiguttulate content, in KOH 5% turning brownish. Up to 5(7) µm broad. Textura: the medulla is a textura intricata with 1.5-5 µm wide, often branched hyphae. The excipulum is a textura prismatica with 4.5-20 µm wide, often brown hyphae. Best wishes, Gernot

Heterosphaeria patella 230614

Goog morning friends This small black soft 800-1.200 µm diam. was growing probably on Urtica dioica, at semi-alpine place in a snowfield (nevero). It is young and more or less dead, but I think enough live to identify it. Hemiamyloid asci, with croziers, elipsoid-cylindrical spores of (9.8) 11.1 - 14.1 (17.1) x (2.8) 3.4 - 4.0 (4.6) µm; Q = (2.8) 2.9 - 3.9 (5.1) ; N = 37; Me = 12.6 x 3.7 µm ; Qe = 3.4 Ectal excipulum brown with textura angularis and hard.

Agyrium or what?

On the upper side of fallen, decorticated, +/- undecayed logs of Picea and Pinus, found in association with Tromeropsis microtheca and Claussenomyces atrovirens in Tübingen-Pfrondorf, Hägnach, 26.III. & 2.IV.2017, E. Weber & H.O. Baral. On whitish areas of wood, not lichenised Asci with inamyloid tholus but outer wall hemiamyloid (red, hardly any blue at low concentration). Sporex ca. *12-13 x 5.3-5.5 µm. We thought it should be an Agyrium, and actually it is very similar to A. rufum, but it differs: - spores narrower, with a lower, more biguttulate oil content - more purplish-rose instead of orange exudate - smaller apothecia (0.17-0.3 vs. 0.25-0.5 mm) - IKI almost RR (vs. clearly RB in A. rufum) We found this drought-tolerant species in great abundance, but only on the exposed upper side. There seems to be a lack of literature about this genus. Zotto

Lachnellula ellisiana ? again ?

<div>Hello all,</div> <div>I found another location in New York City where a Lachnellula with long fusiform spores is growing on pine bark. At first I thought Lachnellula ellisiana, but I'm beginning to have some doubts. The spores in this case are not guttulate and the ends are somewhat more rounded than in my earlier collection. For this collection I had to keep it in a moist chamber for more than a week to make it drop spores. There are also some spores with long club-like deformations at the end—I assume these are germinating, but I'm not entirely sure. I have uploaded here a photo of the spores, but for more details there is an observation here:</div> <div><a href="https://www.inaturalist.org/observations/105730915" target="_blank">https://www.inaturalist.org/observations/105730915</a></div> <div> </div> <div>And for comparison to the previous collection:</div> <div><a href="../search_forum/69140" target="_blank">http://www.ascofrance.fr/search_forum/69140</a></div> <div>Thanks in advance,</div> <div>Ethan</div>

White Mollisia-like (?) disco

Hello, friends, This one was collected on the deciduous twig 2 cm in diam. It is a dried specimen and I don't have a good idea about its genus. When I made a mount in tap water 2 times I observed a rich white exudate appearing from a fruitbody with abundant spores floating in it. One time I didn't observed it. Also some (maybe gelatinous) content is visible in paraphyses although they obviously should be dead. Its excipulum was different at the base and at margin. At the base - brown prismatic cells, and near the margin - more elongated hyaline cells. I haven't seen clearly any hairs. Spores are 5.8-7.2*2.3-2.6 um. 2 or more oil drops in spores. KOH-, ascus apparatus IKI dark blue Asci with croziers which grow from the upper part of the ascus base but do not merge with the base. I hope someone can tell me something about the genus. Best regards, Irina

Orbilia on soaked wood

After some time I tried an Orbilia again.... I found it today on a piece of rotten soaked wood, lying in a small creek, half submerged. The few (4-5) apothecia are very fragile and light apricot in colour. Asci are 8 spored, uni- to biseriate, IKI- and with a furcate base. (28-34.5 x 3.2-39 µm, without base) Paraphyses are covered at the tip with a gelatinous mass, shape is capitate and there are septa in the stipe. The spores are ovoid to fusiform featuring a prominent refractive body. (3.2-4.2 x 1.3-2 µm) I believe that I have found O. coccinella two times before. Is it the third time? Regards, Martin

Luciotrichus sp?

Bonsoir, Voici un discomycète à allure de Lasiobolus, récolté le 12/04 sur un tronc très décomposé de Pinus, derrière Barcelone (parc naturel de Collserola - alt. 160 m). Taille entre 0,5 et 1 mm. Pas de trace d'excréments sur le support. Les spores ellipsoïdes mesurent 20-22,5 (23) x 10,5-12,5 µm et sont couvertes de petites verrues d'environ 0,5 µm. Deux guttules « principales » et parfois quelques-unes plus petites sont visibles dans l'eau. Asques operculés, octosporés à spores le plus souvent unisériées, 230-270 x 15-17 µm, négatifs à l'iode. Paraphyses hyalines, le plus souvent recourbées au bout, progressivement renflées au sommet jusqu'à 6-7 µm. Poils jusqu'à 300 x 10-12 µm, peu (voire pas) cloisonnés, hyalins, à paroi épaisse jusqu'à 2,5 µm, souvent renflé à la base jusqu'à 20 µm puis amincis à l'extrême base. Quelques rares poils bifurqués à la base. Excipulum de texture globosa/angularis, cellules d'un diamètre de 15-25 µm. J'aboutis à Luciotrichus, à cela près que la diagnose du genre précise que les spores sont « non guttulatae ». La seule espèce du genre, Luciotrichus lasioboloides, a des spores trop petites pour convenir (15-17x8) et ses paraphyses sont plus minces (1,5-2 µm de diamètre). Je pense pouvoir éliminer L. lasioboloides sur la taille des spores...peut-être s'agit-il d'un Luciotrichus pas encore décrit ? Qu'en pensez-vous ? Pascal

Buenos días Estos pequeños apotecios de unos 2 mm crecían sobre un papel tipo Kleenex o similar que estaba sobre heces humanas, en zona de dunas bajo Pinus, el 14/I/2023. Himenio de color beige claro, exterior más oscuro y furfuráceo, margen diferenciado. Ascas octospóricas, irregularmente biseriadas, con reacción "dextrinoide" en el ápice, tanto en IKI como en KOH + IKI, con croziers, de (160,9) 171,6 - 219,9 (231,9) × (13,2) 15,4 - 20 (21,7) µm; Q = (8,1) 9,6 - 12,5 (14,3) ; N = 36; Me = 196,6 × 18,1 µm ; Qe = 10,9, con presencia de numerosas esporas deformes germinando, incluso en el interior del asca. Ascosporas fusiformes, lisas, de (13,9) 14,5 - 16 (16,6) × (6,6) 7,1 - 7,8 (8,1) µm; Q = (1,8) 2 - 2,1 (2,2) ; N = 64; Me = 15,2 × 7,5 µm ; Qe = 2. Paráfisis cilíndricas, multiseptadas, ligeramente engrosadas y torcidas en el ápice. Excípulo medular con textura prismatica mezclado con células subglobosas. Expículo ectal con textura subglobulosa. Por las características macro creo que se trata de una Pseudombrophila, pero no encuentro ninguna que encaje con esas esporas. Gracias por vuestra ayuda. Miguel Ángel Ribes

500 and counting

Over the last few years a vague idea has crystallised into a firmer project. My aim is to produce images of 1000 fungal taxa, all of those images (preferably) at publication standard. The criteria are that: (a) all the fungi will have been seen and confirmed by myself (or other mycologists whose opinion I trust) (b) as far as is possible the images shall consist of composite 'plates' showing all the important diagnostic features (including measurements, where appropriate), to help others with their determinations (c) the images are all based on (Watsonian) Yorkshire (UK) material (d) at least the critical identifications will be based on fungarium material lodged in suitable regional or national collections; all expert opinions given with regard to identification will be acknowledged (e) when finally produced the resulting work will be either produced free for all or sold to benefit an appropriate mycological charity; I do not want to benefit financially from any of this. I have to be honest - quite a number of those species will be basidio's - but asco's are my first love! 1000 species sounds a lot, but is actually considerably less than 20% of the Yorkshire total. One problem I have found is that now, when I have got better at the whole procedure (and have better hardware to produce the images), I find myself producing newer and better images of species already dealt with, but that will continue - though it slows up getting to the 1000 (quality is as important as quantity). I set myself the target of getting to 500 taxa by the end of 2014. However, for personal reasons I don't need to go into here, this year has been more than somewhat gnarly and I did not think I would be capable of achieving that target. To my great surprise, and thanks to the weather, November and December have proved very productive. When totting up a few days ago I realised I was close to that 500 target and on Christmas Eve I was on #499. So I went out on Christmas Day to have a short walk from home (in central Huddersfield) to see if I could get that 500th species - I was pretty sure I could as there are many common species I have not dealt with yet. A lot of agarics are still in evidence (if fading somewhat) and I pretended I had not seen numerous basidiomata of an Agaricus ringing a Pinus tree in the local cemetery. It looked like I was going to have to work with a nice collection of Xylaria hypoxylon - 'candle snuff' in English, quite suitable for Christmas! But as I was returning home, on a whim I took an alternative route and there, almost calling out to me was a clump of Aleuria aurantia. It all fell into place - * the Christmas orange: http://en.wikipedia.org/wiki/Christingle * those wonderful ascospores, looking rather like Christmas tree decorations * and finally a Persoon species (he is my mycological hero, for various reasons) Joyeux Noël!

asco indéterminé sur urtica dioica

Bonjour à tous, Lorsque je l’ai ramassé hier sur tige morte d’Urtica dioica je me suis dit que cette petite fructification subglobuleuse de 0.3 à 0.4mm avec ses petits tétons devait être Lasiospheria acuta. Evidemment avec mon inexpérience je m’étais trompé car la micro ne correspond pas du tout. Je n’ai malheureusement pas pu déterminer l’espèce aussi je sollicite votre aide. Fructification de 0.3-0.4mm x 0.2mm subglobuleuse, face sup et inf le plus souvent aplatie – noire lisse - ostiole papilliforme – naissant sous l’épiderme de la tige morte qui se déchire à mâturité. Quelques poils de fixation bruns septés à la base. Asques énormes 160-300 x 10-11 contenant de nombreuses spores très longues parallèles ou torsadées dans l’asque. Spores 70-100 x 25-30 septées avec un renflement caractéristique et constant au niveau du second segment tandis que l’autre extrémité + filiforme se termine en forme de queue. Merci pour votre aide. Daniel

Discomycet on cone of Picea

Hello, a few days ago I found this Ascomycet on a cone of Picea. When getting old the apothecia turn reddish-brownish. Asci are IKI b and the spores are 9-10 x 3.5-5 µm. The apos are sessile. I thought maybe a Calycina but I did not found a species that fits with my collection. Best wishes, Gernot

Helvella phebophora?

Buenas tardes. Empezaré por presentarme, pues se trata de mi primera participación en este foro. Mi nombre es Tomás Illescas, presidente de la Asociación Micológica Sierra de Córdoba. Vivo en un pequeño pueblo de la Sierra Norte de Sevilla (España). El motivo de mi consulta es que he acabo de recolectar esta pequeña Helvella cuya imagen adjunto, encontrada en bosque mixto de Quercus y Pinus, de unos 3 cm. de ancho x 4 de alto. Al verla pensé en Helvella phlebophora, por el color uniforme marrón grisáceo y la mitra bastante lisa, soldada al pie, pero la microscopía no cuadra. Esporas de 16-19 x 10-12 micras con una gran gútula, lisas en estado maduro pero groseramente verrugosas en estado inmaduro. Paráfisis de 200 x 3-4 micras, con terminaciones de hasta 8 micras de ancho, septadas y con engrosamientos en la base. Ascas de unas 15 micras de ancho. Agradecería vuestras opiniones. Un saludo, Tomás Illescas

Asco on Potentilla erecta leaves

Hi to all: What's tour opinion about this small (up to 0.3 mm) ascomata, turbinate, witish, later yellowish brown, and finally greyish- blue by the existence of an exudate blueish?. I think could be a Calycellina species unknow for me. They grew on overwintered leaves of Potentilla erecta. Many thanks!

Hamatocanthoscypha/Psilocistella

Good year. I present this specimen found on fallen cone P. halepensis. Might fit with Psilocistella conincola (Hamatocanthoscypha conincola not know if it would be valid) but Raitvir think is an extreme form of H. laricionis? The case is that following the key Raitvir leads me to H. ocellata. To see what you think about: Apothecia white (is kept in after time) slightly stalked up to 1 mm in diameter Buen año. Os presento este especimen hallado sobre cono caido joven de P. halepensis. Podría encajar con Psilocistella conincola (Hamatocanthoscypha conincola, no se si sería válido) aunque Raitvir piensa que es una forma extrema de H. laricionis?? El caso es que siguiendo la clave de Raitvir, me lleva a H. ocellata. A ver que os parece a vosotros: Apotecios blancos (se mantinen tras tiempo) ligeramente estipitados de hasta 1 mm de diámetro

Thyronectria balsamea

Bonjour, un copain de moi a trouvé une Nectria sur Pinus avec des spores muriform, qu'il a détérminé (avec "?") comme Thyronectria balsamea. Est-ce que quelqu'un (je pense pour Christian en effet *gg*) peut lui donner des citations de literatur, description ou quelque chose pour qu'il peut comparer son trouvaille? E.g. la description dans Booth (1959)? Merci beaucoup en avance, Andreas

Hongo parecido a Mollisisa

Hola. Tengo estos hongos que se han recogido creciendo sobre ramas sin descortezar de Pinus uncinata a una altitud aproximada de 2100 m de altitud. Tiene ascas IKI- de (63-)65-80(-81) × (10,7-)11,5-14(-14,5) µm, esporas de (8,6-)11,8-14,3(-16,7) × (3,9-)4,4-5,2(-5,6) µm, Q = (2-)2,3-3(-3,4), N = 75, Me = 13 × 4,8 µm, Qe = 2,7, con un septo transversal y paráfisis con una gran VBs que se colorean de amarillo con KOH. Aunque con las medidas de ascas y esporas un poco superiores pienso que es el mismo hongo que tiene el señor Baral en sus carpetas de Mollisia on woord + bark (IKI- spores 9-12.5 x 3.5-4.5) y me pregunto si no hay un nombre para este hongo actualmente.

Hyaloscypha

Buenos días / Good morning Viendo el mensaje de Roland Labbé de ayer titulado "Calycina sp" (Hyaloscypha fuckelii var fuckelii), pienso que tengo una recolección igual o muy parecida. Con las claves que envió Zotto llego a H. fuckelii var fuckelii o H. aureliella, porque no sé interpretar correctamente si tiene o no resina amarillenta en los pelos (aunque en las fotos macro así parece) y si los pelos son romos o no. Las medidas son estas: _________________________________________________________ Seeing Roland Labbé's message about "Calycina sp" (Hyaloscypha fuckelii var fuckelii), I think I have an equal or very similar one. With the keys that Zotto sent I come to H. fuckelii var fuckelii or H. aureliella, because I do not know interpret correctly if my recolection has or not yellowish resin in the hairs (at the macro photos it looks like) and if the hair is blunt or not. The measures are these: Sporal measurement (1000x, watter, fresh material) 5.3 [6.5 ; 7] 8.1 x 1.5 [1.9 ; 2.1] 2.5; Q = 2.6 [3.3 ; 3.5] 4.2 ; N = 40 ; C = 95%; Me = 6.73 x 1.98 ; Qe = 3.42 Hair measurement (1000x, water and congo red + Phloxina B, fresh material) 25.3 [38.5 ; 43.9] 57.1; N = 35 ; C = 95%; Me = 41.19 Muchas gracias / Thnak you

Scopinella? from Chile

Estimados Mi nombre es Pablo Sandoval y estudio macromycetes de Chile, entre ellos obviamente los ascomycetes. Y aunque conozco hace ya bastante tiempo este grandioso foro, recien ahora me he decidido a participar. Ahora mi consulta es la siguiente: Hace algunos años encontre en la cordillera de Los Andes, al sur de Chile, algunos estromas desarrollandose sobre ramas vivas de Nothofagus pumilio (lenga), y la verdad nunca he podido averiguar de que se trata, las esporas me parece que tiene engrosamientos en la pared y me recuerdan a las de Scopinella solani. Si a alguien le resulta familiar esta especie y me pudiera orientar, se lo agradecería mucho. Adjunto fotos, las macro estan en mm y las micro en um. Saludos cordiales

Morchella conica

Bonsoir. J'ai trouvé sous Larix decidua ces morilles qui toutes avaient un stipe court et épais. J'en ai fait Morchella conica bien qu'en général, le stipe est fin et cylindrique. Qu'en pensez-vous? I have found under Larix decidua these morels. They have all short and thick stipes. I think it's Morchella conica but in general, in these species, the stipe is thin and cylindrical. What do you think about that? Yannick Mourgues

Muestra en Pino 05-02-15

Hola, tengo esta muestra recogida en rama caida de Pinus halepensis, a unos 450 m de altitud. al verla me recordo a Sarea resinae, pero mi muestra tiene esporas que son el doble de diametro, lo cual la descarta. lo mas parecido que veo es Byssonectria semi-immersa, que tiene esporas diferentes lo cual la descarta tambien. En toda la documentacion que tengo ya no veo nada parecido. La otra opcion que estoy pensando es que lo que yo creo son esporas dentro del Asca, puedan ser nucleos y no esten las esporas formadas, en este mensaje envio microfotografias de ascas en las que se ven lo que creo son esporas, a ver que les parece. 0,96 diametro. Parafisis de dos tipos, unas finas y abundantes de X1,7--X2 y otras septadas X4--X5. Ascas con Croziers, de 49--52 X 5--6 (inmaduras ) Esporas esfericas de 4,5--5,2, solo he podido medir 7 fuera del Asca. Pelos en grupos densos de 43--62 X 4--4,5, formados por celulas a modo de escamas. Un saludo Rafael

Propolis viridis

Buenos días ¿Podría ser esto Propolis viridis? Según el CABI, P. viridis es sinónimo de P. versicolor, y a su vez, el nombre actual es P. farinosa. Sin embargo, la mayoría de las publicaciones de P. versicolor tienen el himenio blanquecino o de blanco sucio a blanco azulado, pero nunca un color verde-azulado tan intenso. Las medidas esporales de P. versicolor podrían coincidir con esta recolección en cuanto a longitud esporal, pues hay una gran variación en la literatura, pero son más estrechas, entre 5-7 µm, y además son mayoritariamente alantoides, mientras que las nuestras tienen entre 8-11 µm y son mayoritariamente elipsoidales. Con las claves de Baral podría descartarse P. versicolor, por el color persistente verdoso-azulado; por las esporas bigutuladas iríamos a P. viridis o bien a la recolecta de Propolis sp de Madeira (HB 5961c E). Las medidas de las ascas no coinciden con las de P. viridis, son bastante más grandes y cercanas a P. versicolor o a la recolección de Madeira. Saludos, Miguel Ángel _________________________ Good morning Could be this P. viridis? According to CABI, P. viridis is a sinonim of P. versicolor, and the actual name is P. farinose. But in the books P. versicolor has a more or less white himenium, but never green-blue so intense. Sporal measurement of P. versicolor are similar in length to our record, but are narrow (5-7 µm) and are allantoids; our sporal length are 8-11 µm and usually ellipsoid. With Baral key I think it is not P. versicolor, cause de the green-blue color; with bigutulated spores I arrive to P. viridis or to the record of Propolis sp from Madeira (HB 5961c E). Asci measurement don’t match with P. viridis ones, are bigger and nearest to P. versicolor or Madeira’s one. Best regards, Miguel Ángel

Pyrenopeziza chailletii (Pers.) Fuckel

Good morning, I believe this to be Pyrenopeziza chailletii (Pers.) Fuckel. That is, Fuckel's original description denoting spores 8 microns long. Most later finds have spores averaging 17-22 microns and it was thought Fuckel had made a mistake. Spores hyaline, 7.6-9.4 x 2.0-2.5 µm, with small drops at each end. Asci 34-55 x 4.2-7.0 µm, paraphyses sparse and difficult to see. A useful debate on the genus, and this species in particular, can be found here: http://www.wildaboutbritain.co.uk/forums/fungi-forums/47409-problem-pyrenopeziza.html Any comments welcome.

Mycogone cervina on Helvella

Hi, yesterday I found a decaying Helvella covered at the spore bearing part with the anamorph of Hypomyces cervinigenus i.e. Mycocone cervina. About the species of the Helvella I am not sure. Can it be H. lacunosa with spores 21-21.4 x 12.4-13.6 µm? A bit large, aren't they better queletii also by shape? The globose conidia of the Mycogone measure (without the ornament) 10.5-14.5 x 10.8-14 µm. Habitat was on the side of a path on calcareous sandy soil under deciduous trees. Cheers Martin

Scutellinia with large spores

Hello. I found a small group of Scutellinia on wet mud/soil in Hampshire, UK. They were orange/red up tp 3mm diameter with short (under 500 microns) hairs covering the outside. The hairs were deeply rooted with 4 to 6 septa, dark and fairly equal in length. The spores in the asci measured 27 X 13.5 (QE 2) and appeared to be lightly ornamented. It is difficcult to decide if it is warts or ridges or both. I am waiting to see if I can get some ejected spores but here are the pictures. I know that Scutellinia are hard to pin down but there don't seem to be many with such large spores. Many thanks David

Unguiculariopsis, again

Collections of Unguiculariopsis reported on this forum have stimulated some discussion, but it is not clear from this how host-specific they are. I have recently collected one on Nemopanthus mucronatus (Ilicaceae) near my home in New Brunswick. In Zhuang's monograph it is most similar morphologically to U. adirondacensis. However, it is definitely not associated with discomycetes as U. adirondacensis should be. The only possible host for mine might be a very decayed layer of a corticioid fungus, perhaps a species of Peniophora. If I use host for my determination I get U. acerina, which has much longer excipular hairs. Are the collections of Unguiculariopsis species seen by members of this forum always associated with a host? Is it possible that host-specificity has been overemphasized?

Balsamia polysperma ?

Bonjour, j'ai trouvé ce champignon en zone de lette sur la côte landaise sable avec cistes, à proximité de fourrés de Pinus et Quercus suber les spores m'ont orienté vers le genre Helvella dans les réponses à la recherche sur ce genre, je suis tombé sur Balsamia et il me semble que B. polysperma a de nombreux points communs avec ma récolte (après recherche sur le net) quelqu'un peut-il me confirmer ce genre avec le peu d'éléments photos dont je dispose ? j'ai malheureusement perdu l'exemplaire récolté et ne dispose donc pas d'éléments complémentaires si ce genre peut être confirmé, quelles espèces trouve-t-on en France et existe-t-il une clé pour les différencier ?

Leucoscypha patavina vs L. semi-immersa

I do not have clear which is the difference among L. patavina and L. semi-immersa. I have this L. semi-immersa record identified some time ago by Zotto: Http: // www.micobotanicajaen.com/Revista/Articulos/MARibesR/Aportaciones006/Leucoscypha%20semiimmersa%20130107%2006.pdf But now I have found this another one in beach dunes in Mallorca (Spain) Certainly, is the correct name of L. patavina now Pustularia patavina? Thanks, ______________________________________________________ No tengo claro cuál es la diferencia entre L. patavina y L. semi-immersa. Tengo esta recolecta confirmada hace tiempo por Zotto: http://www.micobotanicajaen.com/Revista/Articulos/MARibesR/Aportaciones006/Leucoscypha%20semiimmersa%20130107%2006.pdf Pero ahora he encontrado esto otro que adjunto en dunas de playa en Mallorca (España) Por cierto, ¿el nombre correcto de L. patavina es Pustularia patavina? Gracias Miguel

¿Paratrichophaea boudieri?

Hola a todos. He cogido unos hongos que pienso que puede ser Paratrichophaea boudieri, pero me hacen dudar las esporas multigutuladas y tampoco he leído nada sobre el contenido de las paráfisis. ¿Que os parece? Apotecios hasta de 6 mm, creciendo de marera gregaria sobre pequeñas ramas y acículas en descomposición de Pinus halepensis, cupuliformes, con el himenio liso, blancuzco y el margen y exterior cubiertos de pelos marrones. Pelos hasta de 850 µm de longitud, generalmente acuminados, multiseptados, marrones, de paredes gruesas, en algunos casos de base bulbosa. Escípulo ectal compuesto por células hialinas de textura gobulosa o gobuloso-angular. Escípulo medular compuesto por células alargadas, hialinas, de textura intrincada. Ascas de (270-)290-325(-330) × (11,5-)13, 5-18,5(19) µm, cilíndricas, estrechándose en la base, octospóricas, operculadas, no amiloides, con crociers en la base. Ascósporas de (18-)19-22,5(-23,5) × (8-)8,5-10(-11) µm, Q = (1,8-)2-2,4(-2,7), N = 90, Me = 20,9 × 9,3 µm, Qe = 2,2, de estrecha a largamente elipsoidales, lisas hialinas, multigutuladas en su interior. Paráfisis cilíndricas , septadas, multigutuladas en su interior, con el ápice poco o nada engrosado de (2,8) 3,1 - 4,3 (5) µm de anchura. Saludos. Salvador.

Lachnellula arida ?

Bonjour à tous, Je retrouve Ascofrance avec plaisir après de longs mois d'absence. Je voudrais partager avec vous la récolte d'un petit discomycète trouvé tout récemment sur des branches d'épicéas (rectification : sur branches de mélèze) tombées à terre (une coupe de bois a été effectuée l'an passé dans la zone prospectée). La zone est humide et la neige vient tout juste de fondre. La récolte a eu lieu dans les Alpes-Maritimes, le 10 mai, le long de la piste de l'ancienne vacherie du Devensé, à 1800 m d'altitude environ. Description : je fournis une vue d'ensemble prise sur le terrain et deux macros. Les apothécies sont courtement stipitées et mesurent jusqu'à 6 mm de diamètre. La face extérieure est brune et finement velue. L'hyménium est jaune d'œuf ou jaune d'or, avec parfois quelques cercles concentriques. Les spécimens les plus jeunes sont cupulés, les plus âgés sont souvent pulvinés. Microscopie : les spores sont lisses (en DIC et à fort grossissement), hyalines, ellipsoïdes, de 7,5-8,3-10 x 4-4,4-5,5 µm (Q = 1,5-1,9-2,1) dans l'eau (24 spores matures mesurées sur sporée). Les paraphyses contiennent des pigments jaunes peu denses. Les asques ne donnent aucune coloration dans le liquide de Lugol. En l'état actuel je pense à quelque chose comme Lachnellula arida (W. Phillips) Dennis. Cette détermination vous semble-t-elle plausible ? Je serai très heureux d'avoir votre avis sur la question. Il me reste des échantillons pour effectuer d'autres observations si nécessaire. D'avance un grand merci pour votre aide ! Cordialement. Hello everyone, After being absent for a while, I am here again with great pleasure. Today I would like to show you a small discomycete recently found on spruce (this is wrong : please read larch instead of spruce) twigs fallen on the ground (there was forest work on this site last year). The area was wet and the snow has just melted. The exact location is in the Alpes-Maritimes along the track of the old farm of Devensé, circa 1800 m. Please look at the given pictures and macros. Apothecia are shortly stipitate, up to 6 mm in diameter. The outer part is brown and finely hairy. The hymenium is yellow, sometimes with some visible concentric circles. The younger specimens are generally cup-shaped and the older ones are often pulvinated. Microscopy: the spores are smooth (DIC illumination at high magnification), hyaline, ellipsoid, 7,5-8,3-10 x 4-4,4-5,5 µm (Q = 1,5-1,9-2,1) in water (24 mature spores, out of the asci). Paraphyses contain yellow pigments. The asci do not react to Lugol staining. As far as I know, this species could be something like Lachnellula arida (W. Phillips) Dennis, but I would appreciate your comments on this determination. Does it sound good for you? I still have samples in the fridge for performing complementary observations if necessary. Thank your very much for your kind help. Best regards.

Posible Rhytismatacea

Hola amigos: Hace un par de dias recolecte sobre estrobilo de piña (Pinus pinea) unos pequeños apotecios anaranjados de 2-3 mm. de diametro aproximadamente, pulvinados y erumpentes sobre la capa cortical del estrobilo. He echo la micro y me encuentro con ascas de 150-180 µm., no amiloides, me han parecido octosporicas(me ha sido imposible contar el numero de ascosporas),base aporrhinca, con ascosporas filiformes de dimensiones exageradas de longitud (95-110 µm.) y 2-3 µm. de grosor,y tres o cuatro septos,con uno de los extremos apuntado y el otro extremo achatado -redondeado; parafisis tambien filiformes con el apice engrosado y a veces curvado como en las Otideas. He estado mirando en la bibliografia que dispongo y solo me aproximo a que pudiera pertenecer ( por la forma esporal y la forma de aparecer los apotecios erumpentes en el substrato) al orden Rhytismatales y dentro de el , como posibles géneros Coccomyces o Therrya , pero no encuentro ninguna especie dentro de ellas que me encaje. Aunque muy parecida por el aspecto macro de Coccomyces strobi, el tipo de pino en que aparece no coincide con el de mi recolecta.Respecto al otro genero con esporas filiformes septadas y tan largas, se parece mucho la micro a Therrya pini, pero el aspecto macro , la coloracion no tiene nada que ver por las fotos que he encontrado y las prafisis no presentan como he visto en la base de datos de una recolecta de Enrique Rubio esas incrustaciones mas oscuras en los apices. Solamente macroscopcamengte he podido encontrar Therrya eucalypti, que presenta esa coloracion , pero el habitat tambien es distinto y no he podido comprobar como es su microscopia. Me gustaria saber si alguno teneis alguna idea de cual puede ser la especie en cuestion. Muchas gracias de antemano.

Helvella solitaria and allies: interpretation and confusion

Dear all. Following the discussion about "Mycogone cervina on Helvella", I tried to check part of the literature on the following species: H. solitaria, H. leucomelaena and H. confusa. I also verify my own data based on fresh collections. Helvella solitaria Karst. and H. queletii Bres. correspond to the same taxon. It is well characterised by its distinct stipe with regular ribs and its brown cupule compressed laterally; spores 17-24 (25) x (12.5) 13-15 µm ; asci with pleurorynchous base. It grows in spring, under hardwood (Populus, Salix, Quercus), near rivers or wet places. Selected illustrations: Boudier (Icon #242 under Cyathipodia dupainii), Bresadola (Icon #1172 under H. queletii), Dissing (1966, fig. 18, under H. queletii), Weber (1972, fig. 27 & 28, under H. queletii), Harmaja (1977, fig. 1), Cetto (1979, #1204, under H. queletii), Breitenbach & Kränzlin (1981, #18, under H. queletii), Häffner (1987: 49), Medardi (2006: 84). Helvella leucomelaena (Pers.) Nannf. is characterised by its dark grey to blackish apothecia (lighter or whitish only at the base), deeply cupuliform, generally subsessile or with a very short stipe and less or more visible ribs; spores (19.5) 20-23 (24) x 11-13 (13.5) µm; asci with aporynchous base. It grows in earlier spring, strictly under Pinus. Selected illustrations: Boudier (Icon #249, under Acetabula leucomelas), Dissing (1966, fig. 8), Marchand (1973, #195), Kränzlin (1981, #27, under Paxina leucomelas), Häffner (1987: 27), Schmid & Schmid (1991, #51), Dähncke (1200 Pilze, #1115). Helvella confusa Harmaja. The problem is more complex. The name was published by Harmaja in 1977, based pro parte on the interpretation of H. solitataria sensu Dissing (1966). It seems that the description is a mix of H. solitaria s. Dissing and H. leucomelaena. The holotype is the collection illustrated by Dissing on its fig. 10. No ecological data is provided. After Fidel Landeros, this sample corresponds to H. leucomelaena! So this collection could represent specimens of H. leucomelaena with unusual long stipe... In the same time, several mycologists (including me) use the name H. confusa for a taxon growing from May to July, under Picea abies, characterized by its grey to grey-brown colour and its white stipe with less or more distinct ribs; spores 20-23 (24) x (12.5) 13-14.5 (15) µm; asci with aporynchous base. I think this is Häffner (1987) who was the first to use this name for such a taxon. Selected illustrations: Häffner (1987: 19), Cetto (1993, #2915), Medardi (2006: 79, under H. leucomelaena). Harmaja (1979) compares different species (including H. leucomelaena and H. confusa) in a table, but the differences between these two taxa seems tenuous. About H. confusa, he cites as illustration the plate 653 (as Paxina acetabulum) from the book 700 Pilze by Dähncke. I do not have this edition to verify. Maybe this confusion comes from the difficulty, in the Nordic countries, to separate collections of the two taxa, but the ecology is crucial. I attach 3 photographs of my collections. All comments and experiences are welcome.

petite leçon

J'aimerais que vous m'aidiez à apprendre quelque chose... Quand on trouve un asco avec des asques remplies de "spores" en grand nombre, on est quelquefois dans une phase de maturité. Peut-on être dans une phase qui donnera des spores secondaires très différentes? oui? A partir de mon champignon, quelle est la première phase et quelle est celle qui approche de la maturité? photo1, photo 2 Je n'ai pas de connaissances fondamentales, et j'ai l'impression que 2 scenarios sont possibles... Merci de votre aide. jean pierre

Discomycete negro ¿liquen?

Tengo estos ascomas negros, que he cogido creciendo en ramas muertas y descortezadas de olivo, (Olea europaea). Las ramas están fuera del entorno donde se cultivan los olivos. Se han llevado a una finca a 1745 metros, para el aprovechamiento del ganado. El que las ascas sean totalmente amiloides me hace pensar en que es un liquen, pero la total ausencia de talo me hace dudar, ¿Qué opináis vosotros? Gracias. Ascomas negros, discoides, no estipitados, hasta de 1,2 mm de diámetro, que en contacto con KOH 5% reaccionan desprendiendo una pigmentación amarillo-anaranjada. Ascas cilíndricas, afinándose hacia la base, octospóricas, unitunicadas, sin aparato apical, que produce la descarga por una rotura del ápice, euamiloides en toda su longitud y sin croziers en la base, de (71-)77-92(-99) x (7,0-)7,9-8,6(-9,3) µm, N = 15, Me = 84 x 8,2 µm. Ascosporas biseriadas en la parte superior del asca, cilíndricas, curvadas o rara vez rectas, lisas e hialinas, sin contenido de aceite o con algunas pequeñas gútulas en los extremos, unicelulares o con un septo cuando están muy maduras, que parecen desacerse en ascocondios finalmente, de (7,7-)9,6-14,7(-15,8) x (2,4-)2,7-3,2(-3,6) µm, Q = (2,5-)3,3-5,4(-5,7), N = 52, Me = 12,2 x 2,9 µm, Qe = 4,2. Parafisis hialinas, multiseptadas, constreñidas en los septos, con algunas pequeñas gútulas de pigmentación amarillenta en su interior, ramificadas en el ápice, donde están cubiertas por una masa marrón oscuro o casi negra. Salvador.

Ascomycète bleu de très petite taille

Bonjour le forum, Je me permets de solliciter votre aide pour la détermination d'une espèce très discrète (< 1 mm de diamètre), d'un bleu uniforme intense, récoltée hier sur bois d'épicéa. Je vous joins une fiche contenant la description macro et micro, avec des photos. Clichés en plus haute résolution sur demande. D'avance, je tiens à m'excuser pour la qualité approximative des clichés de microscopie, mais la faible taille des éléments n'aide pas... Un grand merci pour votre aide précieuse et à bientôt. Cordialement, Edouard Evangelisti

Phaeohelotium binucleatum

Voici une récolte tout à fait intéressante qui me semble correspondre à un taxon décrit ad interim par Bernard Declercq dans sa clé des Hymenoscyphus s.l. Hormis l'habitat, les autres caractères me semblent coller et surtout, phénomène le plus intéressant : la coloration des "noyaux" dans une solution idoée (Lugo ou Melzer). Je joins deux photos prises par Jean-Louis Cheype qui a eu, comme moi, la chance de récolter l'espèce lors de la session mycologique FMBDS/FAMM à Lamoura (Jura). A terre, sur de petits débris ligneux enfouis (aiguilles de sapin), plusieurs apothécies jaune ; Ø 2-3 mm Asques cylindracés, avec crochet, octosporés, 115-130 × 7-9 µm, à pore apical IKI-. Paraphyses hyalines, cloisonnées, sans vacuole. Spores elliptico-fusiformes à fusiformes ± larges, 10-13 × 5-5,7 µm, hyalines, sans véritables guttules mais à contenu "granuleux", présentant dans le lugol deux tâches brunes distinctes. Excipulum ectal de textura subglobulosa/angularis, à cellules brun jaune. On soil, on dead fallen needles of Abies buried, several yellow apothecia ; Ø 2-3 mm Asci cylindric, with crozier, 8 sp., 115-130 × 7-9 µm, with apical ring IKI-. Paraphyses hyalin, septed, without VB. Spores elliptico-fusoïd to fusoïd ± enlarged, 10-13 × 5-5.7 µm, hyalin, without guttules but with granulous content, showing two brown spots in the lugol reagent. Ectal excipulum of textura subglobulosa/angularis, with brown yellow cells. Si d'autres membres du forum ont déjà observé ce champignon et/ou ce phénomène de coloration, nous sommes, Jean-Louis et moi, intéressés par toute information. D'autre part, s'agit-il réellement d'une coloration des noyaux de la spore ?

neournula pouchetii

Bonsoir. Le 24/03/2007 j'ai eu la surprise de trouver dans mon jardin cet asco dont les photos sont jointes à ce message. La macro m'a tout de suite fait penser à Neournula pouchetii. La micro a donné: Spores elliptiques 14x24 um lisses dans l'eau mais quelques verrues minuscules et pas évidentes à voir au bleu coton. Asques cylindriques 250x16 um Paraphyses septées 250x4 um La micro me semble donc correcte pour ce taxon. Seul hic : L'habitat... Il n'y a en effet dans mon jardin que des pins sylvestre et des noisetiers. Il n'y a jamais (et j'en suis sûr!) eu ici de cèdres (ce qui est l'habitat normal pour ce champignon). Donc question! Me suis-je trompé? Si non, est-il signalé quelque part que N. pouchetii peut venir ailleurs que sous Cèdres? Merci pour vos réponses. Yannick Mourgues
