ombrophila ??

Hello, I'd like some help. Yesterday I found twe asco;s in the sand and mosses nearby. I really don't have any idea what this can be. The measure of the asci are 77-95 x 8-9 µm and the spores 12-15 x 5-7 µm. As far I can see the asci are J- First I did some Baralse and thought the tops are a little blue. With Melzer I couldn't see blue. But I thought toe see the the top of the asci looking warty. It's a mystery for me. Can someone give me some help?

Ombrophila? hemiamyloid

Hi everybody, I got this find from a friend. Apothecia between mosses on soil, up to 4,5 mm, pale orangepink, stem 2,5 mm long, whitish. Asci 80-82 x 10 with croziers (I think), biseriate, IKL positive with red and lilac ascus-raktion, blue after KOH treatment. Paraphyses hyalin without guttules, up to 4 µm wide, septate. Spores becoming 1-septate, hyaline (12-15) 13,6 x 3,75 (3-4) µm, oil +/- 1. I'm not sure with Ombrophila. Regards Maren

Koszka Attila, 24-10-2019

Ombrophila?

Any idea? By a spring-head, on the wet, loamy ground (not on wood), among Funaria hygrometrica mosses, near by Octospora excipulata and Cheilymenia crucipila. Fruitbodies 1-3 mm. I collected and examined the first time. It has inoperculate asci, and biguttulate, slightly Ombrophila-like spores.

Godorova Olga, 23-01-2015

Ombrophila or Roseodiscus sp.?

Hello. I've found these on rotten stems of grass in a coastal sandy region of Israel. I think, I've seen them before and they are pretty common, but maybe often overlooked. Fruit bodies about 2-4 mm. Ascos about 160-180*18-22 mkm, 8-spored. The spores are arranged in 1-2 raws, about 18-22*7-9 mkm. Paraphises long and slender.

Juuso Äikäs, 09-12-2020

Ombrophila?

This I photographed 7.8.2019 in a swampy depression in a Picea abies dominated forest. Unfortunately there isn't too much information. I returned to the place this year, but couldn't find any new apos. The apos were max. ca. 5 mm wide and I think they had a short stem and were growing from needles and sticks of P. abies. The flesh was gelatinous. I measured some spores in water from a spore print and they were about 11.5 - 13.5 x 4.5 - 5 microns. The ascus pores had a faint amyloid reaction in Melzer's solution. I'm thinking that this could be Ombrophila or maybe Ascocoryne...

Ombrophila limosella

Hello, these fungi grew on soil with small mosses, in a Picea forest in South Bohemia, together with Ramsbottomia macracantha. Ascospores hyaline, smooth, one-celled, (11.3) 11.5 - 13.9 (15.7) × (4.6) 4.9 - 6 (6.1) µm, Q = (1.9) 2.1 - 2.7 (2.8). Asci 71-78.5 x 8.8-11 µm, inoperculate, arising from croziers, IKI+. Paraphyses simple, straight, hyaline, septate, 1.6-2.2 µm wide, apex slightly enlarged, 1.8-3.6 µm wide. Medulla strongly gelified t. intricata, with crystals, hyphae 1.5-3.6 µm wide. Ectal excipulum t. prismatica, cells 14-54 × 10-20 µm. It´s Ombrophila limosella, isn´t it? Zuzana

Ombrophila on fagus cupules

Could somebody help me with this species growing gregariously on Fagus cupules in moist walls of a cartrack in a Fagus forest. Apothecia consist of greyishpink (more greyish the day after collected), gelatinous discs, with a short stalk. Size: up to 4 mm diameter. Microscopic data: Spores: hyaline, smooth, 10,5-13,5x 4-5 mµ, with one large guttule and more smaller. Asci: 8-spored, with hooks, all asci blue reaction with Lugol, 75-85x7-8 mµ. Paraphyses: filiforme. Exipulum: Textura prismatica. Granulation/cristals local on hyphae of the gel and on the excipulumcels. I used the key for Ombrophila species (Baral, 1988). Could this be Ombrophila spec. 6?

Khomenko Igor, 10-01-2021

Ombrophila violacea aff. IKI-

Hi, I think this could be Ombrophila violacea aff. IKI-, but with smaller spores, or maybe I'm very wrong again. https://inaturalist.ca/observations/60009894 On a decorticated log, likely hardwood. Apothecia 1-2mm. 8-spored asci IKI-, croziers(+). Ascospores hyaline, ellipsoid, biguttulate, measure in H2O (5.6) 5.7 - 6.9 (7.9) × (2.6) 2.8 - 3.3 (3.4) µm Q = (1.7) 1.9 - 2.3 (2.7) ; N = 25 Me = 6.3 × 3.1 µm ; Qe = 2.1 Thanks in advance for your response, Igor

Ombrophila?

Hello everybody, I need help with the determination of an Ombrophila(?) on the fallen cupules of Fagus. Collected 18.10.2020, altitude cca 400 meters. Apos max. 2 mm on average, very shortly stalked, whitish or light yellowish. I thought it could be Ombrophila fagiseda, but the color of fruit bodies is strange and I can't see a gelified tissue - so I'm confused now. Medullary excipulum with text. intricata or prismatica(?), ectal excipulum text. globulosa-angularis. Some irregular crystals, if I'm not mistaken...(?) Asci with croziers, Melzer+. Spores are biseriate, cylindrical-ellipsoid with one end wider often, smooth, with some small LBs concentrated around poles. Me= 12.9 × 4.9 µm, Qe= 2.6, N= 30, the length of the spores is pretty variable. Paraphyses with large VBs, which are lost in KOH. Thanks for your help. Marek

Ombrophila from Norway

on decorticated branch of surely Betula (as there were no other bushes in the vicinity) inundated in small rivulet throgh boggy fjell (above the tree line), NP Lomsdal-Visten near Trofors, 30.6.22. The spores I measured about 15-20/7-8 µm, and over-ripe spores seemed to become brownish and septate (Foto 24). One ascus I measured 120/14, and I found no croziers, the apex is euamyloid. Foto 1-3 directly at findplace, "out of the water", 4-6 under bino in studio, 7-8 dried to some extent, 9-11 sections that show textura globulosa (12-13), ending in clavate cells at margo (fotos 14-16). Asci and spores 17-20, paraphyses 21, ascus in IKI 22-23 Does somebody have a hint to a species? I know Ombrophila is very rich in undescribed forms ... Yours, Lothar

Bonsoir à tous, Sur le même cône d'épicéa où se trouvait Hamacantoscypha uncipila, il y avait effectivement un Ombrophila (notamment repéré par Peter) ainsi que sur les autres cônes qui gisaient dans ce drain asséché de la pessière. Mais apparemment, la taille des spores ne correspond pas à Ombrophila janthina !! a) asques IKI+, à spores bisériées, à crochet à la base b) paraphyses filiformes, septées c) excipulum avec grandes et larges hyphes d) spores étroitement elliptiques-subfusiformes, avec microguttules plus denses vers les pôles : 12-14x4,5-5,5 Qu'en pensez-vous ?

White Ombrophila on Picea cone

I found some small (ca. 2 mm wide) white Ombrophilas on a couple blackened Picea abies cones that had fallen into a paludified groove. Asci with croziers, measuring 70 - 80 × 8 - 9 µm, IKI+. Paraphyses cylindrical, with a long VB at the top part. Medulla apparently gelatinized, with small crystals. The spores measure 8.9 - 9.3 × 4.4 - 5.1 µm. O. tetracladia is the best candidate I found. What do you think -- could it fit, or is this something else? ... Or maybe just O. violacea?

Ombrophila violacea?

Hello everybody, I need help with the determination of an Ombrophila on the fallen trunk (Alnus, probably, or Acer, maybe). Collected 1.11.2020, altitude cca 300 meters. I thought it could be Ombrophila violacea or O. pura, but the ascospores are smaller than they should be. Apos max. 6 mm on average, sessile or very shortly stalked, pink or rather pinkish white. Medullary excipulum gelified, in the tissue found conidiophores (really?). Ectal excipulum with text. prismatica (with incrustation?). Ascospores ellipsoid, (5.3) 5.7 - 6.6 (7.6) × (3.5) 3.7 - 4.1 (4.2) µm with 2 LBs and sometimes some others smaller. There was some apos last year on that place too, on this same substrate and at the same time, but it was not examined by microscopy then. Are such information and photos sufficient for a determination? Thanks a lot. Marek

Ombrophila-like (?) from the mine

Hello everybody, I need help with the determination of this Ombrophila-like (?) asco. Collected in a metal ore mine, where the temperature is constant around 8 degrees throughout the year, with very high humidity, the entrance to the mine at altitude cca 620 meters. It grows on a supporting strut from a trunk of Abies (very probably - the local attendant said). Ascomata max. 4 mm on average, stalked, in youth whitish, later turn red during the maturation or drying. Microscopy with the partially dried material unfortunately. Ectal excipulum with vertical textura prismatica, medulla gelatinous. A lot of crystals up to 12 µm large sometimes. Asci with croziers, 80-120 µm long, IKI with blue reaction on the lower part of the ring. Paraphyses cylindrical, sometimes wider slightly or curved at the top, with large VBs. Ascospores hyaline, one–celled, elliptical or narrowly ovoid, Me = 7.5 × 4 µm, Qe = 1.9; with 2 LBs. Thanks for your help. Marek

Ombrophila janthina à confirmer

Dans le même site (aulnaie marécageuse avec ruisseau et en amont une pessière), sur cônes d'épicéas pourris, trempant dans le lit du ruisseau et imbibés, ce qui devrait être Ombrophila janthina. Comme je n'ai pas trop le temps pour le moment de faire la micro, pensez-vous que ça ne peut être que ça ou y a-t-il un risque de confusion (auquel cas je mettrais le cône au frigo pour examen ultérieur) ?

Ombrophila spec.

This Ombrophila was collected in the National Park of "Eifel" in Germany (Northrhine-Westphalia) in 13.8.2015. It grew on wet mud under Salix aurita and Betula carpatica in a boggy forest. Unfortunately, I did not notice how much gelatinous the apothecia were. The living spores were about 11-14(16)/4-5 (6) µm. The apical apparatus was euamyloid, with the lower part reacting more intense than the (nearly negative) upper part (the first and the last two microfotos are in IKI). With the key of Zotto I was coming to Ombrophila spec. 4 - with some bellyache. Can somebody say something? Regards from Lothar

Hola a todos La semana pasada encontré estos ascos en los márgenes de un rio con Equisetum arvenses, en pequeñas raíces no determinada en el suelo. Apotecios de hasta 6mm, estípite bien diferenciado y de color gris con reflejos violáceos. Esporas de 12.5 [14.5 ; 15.4] 17.5 x 3.1 [4.2 ; 4.6] 5.7 µm, algunas con un septo. Mirando en las carpetas del complejo Ombrophila violácea creo que se trata de O. rivulorum , también podría tratarse de O. fagiseda de caracteres parecidos. Agradecería vuestra opinión. Saludos Curro Valencia

Ombrophila ??

Hola a todos. Subo unas fotos de un asco que he encontrado en orilla de riachuelo dentro de pinar con hayas en suelo ácido. Miden hasta 3 mm de diámetro. Ascas amiloides, NO vistos croziers. Esporas de 12-15 x 5,5-7 micras. Yo pensé en una especie de Ombrophila, ¿Qué les parece? Gracias por su ayuda. Rubén

¿Ombrophila violacea?

Hola. Este hongo hasta de 4 mm lo encontré sobre madera de Juglans regia muy húmeda en un arroyo. Tiene la carne muy gelatinosa, con cristales en el escíphulo. Ascas de (69,38) 69,80 - 81,81 (85,07) x (7,19) 7,25 - 8,30 (8,80) µm. con el ápice amiloide. Esporas de(6,14) 6,44 - 7,52 (8,22) x (3,52) 3,69 - 4,13 (4,33) µm. biseriadas, con dos gútulas grandes y algunas más pequeñas aconpañando. Paráfisis septadas en su parte inferior, con la parte superior llena de aceite. Pienso que es Ombrophila violacea, ¿es así? Gracias. Saludos. Salvador.

Ombrophila rivulorum?

<div>Central sweden in a marsh by a shallow lake I found a few of these highly gelatinous discs on wet decomposed debris (mostly Carex and Typha) on the very wet ground. Key in Ellis & Ellis led me to Ombrophila violacea which seemed close enough to begin with, spore size a little big though and only small LBs in spores. So I began digging in "archives" and O. rivulorum was a good fit. Or maybe its O. violacea anyway? The latter automatically being changed into O. janthina in Swedish database Dyntaxa. Can't be right can it?</div> <div>Spores: ~13-14,5x4-5,5µm (IKI+ with 2 red spots)</div> <div>Asci IKI+ blue apically</div> <div>Medulla very loose and with small chrystals.</div> <div>/Johan Myhrer</div>

Neobulgaria on mud?

This group of Neobulgaria look alikes were growing on the mud of the side of a reacently excavated ditch. The asci are blued by Meltzers and the spores are c 7.5 x 3. Can anyone help with the id. Thanks Mal

Ombrophila type on soil

Hi All, During July this summer I found a turbinate Asco looking macroscopically rather like Neobulgaria pura, however, it was growing on calcareous soil and woody debris rather than wood. It was in broad leaved woodland under Acer, Fagus etc. The apothecia were 7-9mm and brownish-pink to brownish-orange with a slightly paler and furfuraceous excipulum. The smooth ellipsoid spores were 20-23x10.5-12 and asci 300-350x7-8 so seemingly much too big for the inoperculate species. Paraphyses were swollen to 7-13. Empty or old asci gave slight diffuse blueing in Melzer's. It seems close to Pseudombropila but I am aware that many of these grow on dung. Again, I would welcome any thoughts. Best wishes, Charles.

Ombrophila sp

Hola. Recogí estos hongos en agosto del año pasado creciendo en una zona turberas muy encharcada, sobre zonas muertas del musgo Philonotis seriata, a 2800 m de altitud. Apotecios blancos o ligeramente anaranjados, estipitados, algo convexos, de hasta 3 mm de diámetro. El excípulo ectal está compuesto por células de textura prismática y el excípulo medular es de textura intrincata. Ascas cilíndrico-claviformes, estrechándose en el ápice, de (83,4) 86,6 - 104 (115,6) × (8,8) 8,9 - 10,9 (11) µm; N = 13, Me = 97,3 × 9,9 µm, con el poro apical euamiloide de tipo Calycina y croziers en la base. Esporas de (10,2) 11,1 - 15,8 (17,8) × (2,7) 2,9 - 3,6 (3,9) µm, Q = (3) 3,1 - 5,2 (6,2) ; N = 53, Me = 13,2 × 3,3 µm ; Qe = 4, cilíndricas, generalmente con un extremo algo más estrecho y algunas pequeñas gotitas de aceite en su interior, que cuando están hipermaduras tienen un septo transversal. Las paráfisis son cilíndricas, bifurcadas en la base, poco o nada ensanchadas en el ápice, sin contenido vacuolar en su interior. Creo que se trata de alguna Ombrophila, pero no me encaja nada. Saludos. Salvador.

Elsa Sousa, 02-03-2017

Hello :-)

I found this asco on a herbaceous stem, it reminds me (macro) neobulgaria, but it is much smaller. Apothecia ~138 microns diam. up to 328 high. Spores are too difficult to measure, I measure only 6 all in asci, 12 x 4 mic. I'm not sure if some are overmature/dead? (asci empty with vb's) and some imature, or all imature. Color pink, greyish around "apothecia". Gelatinous. Any idea? Thanks Elsa

Ombrophila from Sphagnum

I see that Ombrophila's could not be solved very easy, but probably it still worth to post ). #4296 (Ombrophila sp.) in dead part (lower branches) of Sphagnum balticum, ombrotrophic hollow. Common in one location. Apothecia at first turbinate, then cupulate, and later with concave hymenium, sessile, basal part translucent, gelatinous, edge and hymenium white to slightly yellowish, 1–2 mm in diameter, 0.4–0.8 mm thick. Excipulum of upper part of receptalce from prismatic cells, becoming more cylindrical to the edge, edge cells cylindrical, about 25 x 4; hyphae of outer gelatinous layer 3.5–4 broad; medulla from sosage-shaped to ellipsoid cells, near 50 long, 10–15 broad; asci clavate, with crozier, euamyloid ring, 70–83 x 9–10.7; paraphyses cylindrical, without clear vacuoles, medium size 73 x 3; spore ellipsoid, some slightly curved, slightly heteropolar, with many small oils, 12.6 (11.3–13.7) x 4 (3.8–4.2) (n=13).?

Hymenoscyphus

Hi. Here is probably Hymenoscyphus sp. (near repandus ?) I have found on the Aubrac (48), France, on dead stems of grasses, on boggy ground. Apothecia cream to pale ochraceous, reddening when damaged, up to 4mm diameter and 3,5 mm high, stalked. Asci 85-90x8-9 µm, very faintly blue in IKI., arising from croziers. Spores fusiform to sub-cylindrical, aseptate, 13-16(18)x5-6 µm, OCI = 3-4. Paraphyses filled with refractive guttules. What do you think about this specie ? Thank's a lot for your help !

Ombrophila cf. lacustris

I used Zotto's key for Ombrophila. Spores in mine specimen smaller then in Velenovsky as well. Also, he reports wider paraphyses (to 5 mk, but only 2 mk in mine), and larger asci. Growing on leaf sheaths of Carex rostrata in bog, 18.09.2012, N61,058846° E69,467926°. Apothecia turbunate, with long stipe (16 mm), graduating to receptacle (4 mm diam), outer surface of stem covered by slime, disc and outer surface have the same whitish color, translucent. Stem composed of outer gelatinose layer, excipulum (porrecta) and medulla (gelatinosa), receptacle lacking outer gelatinose layer and have excipulum from textura globosa-prismatica, medulla the same; cells of prismatica at stem 46 x 8,7; at receptacle 40 x 15; hyphae in medulla 2,5 broad; outer gelatinose layer hyphae 2 mk broad, ended with enlarged clavate cells up to 8 mk broad; asci cylindrical, with not clear clamp, pore euamyloid, 64,5-74,7 x 5-6,5; paraphyses cylindrical with some enlargement to the tip (2 mk broad at tip), without VBs, segmented, rarely branched; spores fusoid when in asci, upon release becoming strongly curved, many guttulate, 19,5 (18-21) x 2,5 (2,2-2,7) (10 straight spores measured).

Small purplish, flat/conex apothecia on decayed wood

<div>Apothecia 1-1,5 mm in diam., "Ascocoryne-like", tough texture, except the hymenium, which can easily be "scraped" off. Spores broadly ellipsoid-fusiform, ca. 10x5 microns, with two large and several small guttules. Asci weakly amyloid (Lugol, can vaguely be seen in the last photo). No croziers seen. Paraphyses not or only slightly widened at the tips, some are multiguttulate. Excipulum/trama consisting of hyphoid and inflated cells. Growing on highly decayed wood of Ulmus glabra, alongside Orbilia xanthostigma.</div> <div>I'm struggling to find a home for this.</div> <div>Any thoughts?</div>

Ombrophila RC09005

Bonjour à tous, Je sollicite votre aide pour un "Ombrophila" (ou autre chose !) trouvé par l'un de nos étudiants, et qui m'intrigue. Ci-joint un montage pdf de quelques photos prises sur le frais. Macroscopie : ascomes turbinés à pulvinés, sessiles ou presque, lisses, lilas foncé décolorant à lilas-rosé clair avec l'âge, d'aspect gélatineux-ferme, 1-2 mm de diamètre. Microscopie : spores 10,5-11,5 x 4-4,7 µm, Q = 2,5-2,6, ovo-elliptiques, lisses, à contenu guttulé (cf photos), non septées. Asques inoperculés, à paroi épaissie, à anneau moyennement amyloïde assez épais sans extensions (j'ai oublié d'observer la base). Paraphyses courtes, non émergentes, grêles, cylindriques, incolores à contenu hyalin, à 2-4 cloisons, apex arrondi. Péridium en textura prismatica, épais d'environ 300 µm, non gélifié, sans poils ni articles émergents visibles, à pigment lilas (intracellulaire ?). Médulla gélifiée, filamenteuse, à hyphes grêles, mêlées à des éléments terminaux fusiformes, fortement dextrinoïdes, souvent pluriseptés, assez abondants par endroits. Sur faînes de Fagus sylvatica à terre, en milieu humide. Saint-Josse (Pas-de-Calais), bois du Roy, 18/9/2009. Herbier R. Courtecuisse n° 09.005. Je ne trouve pas de signalement de ces "cystides" internes dextrinoïdes dans la littérature, pourtant elles me paraissent remarquables. Merci pour vos indications; je peux compléter les observations sur exsiccata si nécessaire. Amicalement, Pierre-Arthur

Literature search - Eriksson

Hello forum, I'm looking for Eriksson O.E. (2014): Checklist of the non-lichenized ascomycetes of Sweden. Symb. bot. upsal. 36(2). - specifically the pages related to new combination Neottiella janthina (Fr.) Ryman (around p.193). Index fungorum lists this name under synonyms of Ombrophila janthina and some webpages already took it up for the strobilicolous inoperculate as well. So I wonder, if the Fries's type turned out to be an inoperculate after all or if there is another taxon with the same epithet or what. Does anyone have this opus, please? Thank you in advance.

Hello forum, somedody here said, that no fungi grows on Juniperus communis. I tend to disagree ;) These are about 0,5-2 mm wide. The spores are 6-12x3-5 and have usually two droplets, but may have more. The asci are 70-95x6-8, IKI+ blue. The paraphyses seems septate and are enlarget at tips to 2-4 micrometers. Absolutely no idea of what I have found, hopefully someone at forum has more experience of this kind of "no fungus". Marja

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

Pinky-purple Fungus

Greeting A colleague sent me an image a few of days ago of this fungus, growing on acidic soil in a damp area adjacent to boggy ground. The marker is in inches, but I estimate they are about 25-30 mm across. I subsequently received a tired specimen, but still fertile. The set specimen dried out too readily for a spore-drop but I have a decent image from a slide preparation with just the pressure from the coverslip, so should be more-or-less mature: 8.1-11.0 x 3.5-4.4 µm. A later sample had slightly large range: 9.9-12.1 x 3.8-4.4 µm. Asci: 90-103 x 8-9µm (small sample). Paraphyses, heads: 3.0-3.3µm across. Asci and paraphyses are of equal length. The original thought was Ombrophila, but probably too small. Possibly Sarcoleotia turficola, but the spores are too small. Any ideas welcome. Many thanks, Chris

The spores are mostly biguttulate, about 7,5-9(10,5)/3,5-4,5(5) µm, the paraphyses apically 1-2 µm broad and containing conspicuous vacuolar bodies. Can somebody provide me with a hint? In the moment I would call this Calycellina spec. - perhaps there is some similarity with Leptodontidium? Not trabinellum, the spore form does not fit. Best regards, Lothar

Hamacanthoscypha ???

Recevoir un email à chaque réponse dans cette discussion Bonjour, Une sortie dans une tourbière avec Jean-Marc Moingeon du côté d'Oye-et-Pallet, Doubs, (850 m) nous a permis de récolter quelques ascomycètes bien embarrassants pour moi. Je vous présente le premier : Habitat: sur cône pourrissant d'épicéa ayant stagné longtemps dans une mare plus ou moins asséchée, en compagnie d'Ombrophila violacea et bizarrement de Trichophaea gregaria. Apothécies grégaires, 0,5 mm de diamètre, cupuliformes, substipitées, hymenium d'un jaune citrin vif. Surface externe concolore. Marge hérissée de fins poils difficilement observables car retenant des bulles d'air mais le peu que j'ai rencontré m'ont semblé un peu courbés au sommet, septés et à peine renflés à la base. Asques cylindracés à un peu claviformes, avec crochets, J+, 8 spores bisériées. Paraphyses larges, cylindracées, sans cloison, sans goutte mais jaune assez vif, 3 µm de diamètre, non élargies au sommet. Spores un peu en forme de goutte d'eau, sans goutte, lisses, 6-8 x 2-2,5. Les poils (dont je suis peu sûr) et l'habitat sur cône m'ont fait penser au genre Hamacanthoscypha mais je ne trouve rien de correspondant. Avec mes remerciements pourvotre aide toujours bienvenue, Gilbert

green/vinaceous, ± turbinate disc on conifers, often with corticioids - Danish conifer plantations

This tiny fungus has been repeatedly collected during general surveys in Danish plantations. Notes on one collections: Spores slightly clavate, 9 x 3,6 µm, multiguttulate. Asci long-stalked, 8-spored, bb, massive broad plug; with croziers. Paraphyses very slender, extending (in gel?) above asci. Asci 97,5 x 7 µm, widest near apex. The microphotos attached are from this collection. The macro-shot is another collection. We are stuck - maybe you are not :-) cheers Thomas

Tatraea dumbirensis or T. macrospora

The region these are from is Sth. Gippsland, Victoria, Australia I find these on the underside of wet wood in areas of Eucalyptus and Acacia and I am having trouble deciding what it might be (I am an amatuer). I am unsure if the spores might be considered to have pointed ends as per T.macrospora, they aren't curved as T.dumbirensis; the length is slightly longer than in other submissions in the forum but in the forum there is some variation. Asci 150 x 10 Spores: (21-)22 - 29(-31) x 7-9; Q=3.4 Many thanks Peter

Asco on Fagus cupules

Hi there, i found this asco on 25.09.2020 on a Fagus cupules. At first I thought of an ombrophila, but in the meantime I am not so sure anymore. Interesting is that this species seems to have hairs on the underside of the apothecium. Also the reaction of the asci on Lugol is weakly blue. Any idea what it could be ? best regards, Thorben

Neobulgaria pura var. foliacea - a phantom taxon?

Hello everybody, at numerous occasions I have read about A. faginea being confused with N. pura var. foliacea. But I also know that Zotto in his study found out that the type of N. pura var. foliacea is actually A. faginea, e.g.: http://www.ascofrance.com/search_forum/38666. Is there some paper in whitch is this matter already published? So is N. pura var. foliacea a phantom taxon? Thank you for any help. Best regards, Marek

Discinella, Phaeohelotium ?? 011019

Good morning From Aragüés del Puerto, Huesca, this rare species of 1-2.5 mm growing in an old lake filled, in the alpine floor at 2,230 m, between undetermined mosses, in a very shadow and cold place, collected the day 1/10/2019. Macro reminds me a Boudiera, Marcelleina, etc., but I think it has none, although I guess it will not be a Discinella or Phaeohelotium, at least I do not fit with any species of these genera. Ectal excipulum with prismatic-angularis to subglobose texture in the margin. Margin with chains of 3-4 subglobose cells. Medullar excipulum has a double structure: a more internal layer with textura intricata of quite thick hyphae and a more external layer with textura prismatica of very long and thick hyphae. Asci with 8 biseriate spores, IKI -, I believe that without croziers (at least I have not been able to see any clear), of (79.6) 80.5 - 89.5 (95.7) × (7.8) 8, 3-10.8 (11.2) µm; N = 22; Me = 85.8 × 9.1 µm. Cylindrical paraphysis, usually with 1 large BV in the apical cell. Ellipsoidal-subfusiform spores, with 2 LBs at the ends, covered by a gel around its perimeter or only at one end, of (9.3) 9.5 - 10.9 (11.6) × (3.7) 3.9 - 4.5 (4.7) µm; Q = (2.2) 2.3-2.7 (2.9); N = 41; Me = 10.3 × 4.1 µm; Qe = 2.5 Thanks in advance.

Ombrophila(?) - ascospores with great oil content

Récolte le 31/07/2022 – Ozoir-la-Ferrière (77) – France – Etude sur matériel frais vivant. Sur débris de branchettes, sous Carpinus betulinus, en bordure de mare forestière. Apothécies cylindriques, stipitées, à hyménophore convexe, cespiteuses sur le substrat, blanches chez les jeunes puis grisonnant. Taille du plus grand specimen = 3mm de diamètre pour 5mm de haut. Asques bisériées [75 ; 90] x [7.5 ; 9.0]µm à apex de type Hymenoscyphus, IKI+ bb, crochet+. Paraphyses pluriseptées, cylindriques sans épaississement au somment, avec une grande vacuole réfringente (uniquement dans le dernier secteur ?). Ascospores en fuseau [14.5 ; 15.5] x [4.0 ; 4.5]µm soit Qmoy = 3.6 avec un contenu lipidique 4-5 (2 grosses gouttes principales toujours présentes et de nombreuses plus petites autour). Pas vu de poils ni de cellules marginales particulières. Excipulum ectal composé de cellules en textura prismatica orientées parallèlement à la surface de la fructification. Sous-hyménium composé de cellules en boudins (moy. 30x10µm) en textura intricata non gelifiée. Medulla composée d'hyphes grêles et allongés (entre 3 et 4µm de large) en textura intricata gelifiée. Avec les éléments donnés, je pense que j'ai affaire à un Ombrophila (pouvez-vous confirmer?) ; ensuite dans ma doc je ne trouve aucune espèce qui possède des spores aussi grandes et avec de telles guttules. Merci d'avance pour vos commentaires.

Helotiales sur aiguille de Larix

Voici la description d'un Helotiales ressemblant à un Hymenoscyphus mais dont les caractères excluent ce genre... Apothécie stipitée, ± discoïde, entièrement jaune, un peu luisant, Ø 2 mm ; stipe noircissant, greffé sur une aiguille de Larix. Excipulum médullaire de textura intricata ; excipulum ectal de textura globulosa, à cellules Ø 60 µm max. Asques avec crochet, 130-150 x 10-15 µm, anneau apical IKI+ (bb) de type ?Calycina. Paraphyses Ø 4,5-6 µm, hyalines, contenant de nombreuses petites guttules. Spores elliptico-cylindracées, hyalines, non guttulées mais avec de très petites inclusions, principalement aux pôles, 15-19 (20) x 5-6 µm. Dans les asques, certaines spores présentent un "apicule" arrondi, hyalin. Par certains aspects, ça me fait penser au genre Stamnaria... Une idée ?

ascomata with dark hymenium and red-brown excipulum?

Dear forum members, On a rotten piece of wood I found among several fruiting bodies of Mollisia melaleuca other ascomata of which the hymenium is blue-black and the excipulum red-brown. Plenty of paraphyses and only a few asci. 12 days after the find still few asci and mature spores; - Diameter ascomata < 1.5 mm; - Spores: ellipsoid with two drops: 8.4 - 10.5 × 4.3 - 5.2 µm, Q = 1.9 - 2.4; - Asci: clavate, with croziers, IKI (+/- no reaction) in Melzer + (blue): 120 x 7.7 µm; - Paraphyses: hyaline with dark top, filiform, apex round and a bit swollen, longer than asci; - Textura globulosa and ectal excipulum more hyaline and textura intricata. Macroscopically similar to Pattelariopsis atrovinosa but the spores are different. Who can help me with the identification? Thank you very much in advance, François Bartholomeeusen

Fungi of Carpathians

Dear friends. Yesterday evening I returned from a two-week expedition to the Natural Reserves and National Parks of the Ukrainian Carpathians. At this time there is very wet and cool, so a lot of diverse discomycetes presented. I've never seen such an abundance of them - every collected piece of substrate was covered with fruit-bodies! Every day I thought about how it would be nice if you were there also. I plan to visit Carpathians regularly, so if someone wants to join the trip - you're welcome. To share with you the first impressions from the trip, I spread hastily made a selection of photos of some the most common species. Friendly, Alex.

Discinella aff lividopurpurea

Hello forum, this small ascomycete grow on wet bare clayey soil in spruce plantation, 690 m a.s.l., on a place damaged by machines (immediately close to another fungi - Byssonectria deformis and Scutellinia pseudotrechispora). I think it's close to Discinella lividopurpurea (= Ombrophila limosella?), but it has inamyloid asci (I tried IKI, KOH+IKI, KOH+MLZ, but not a trace of bluing) and ectal excipulum at the base of apo is amyloid. Apothecia up to 1,5 mm, turbinate tu substipitate, younger greyviolet, then purplish. Sp. dead (8) 8,3-10,4 (10,5) × (3,1) 3,4-4 (4,5) um, very few free spores. Asci croziers + , IKI-, MLZ-. Paraphyses filiform, not enlarged, content?? Ectal excipulum of textura porrecta, at the base bluing in IKI - or maybe there's some gel that's blueing? Medúlla ?? It reminds the Nicolas' collection here: http://ascofrance.fr/search_forum/3011 with those inamyloid asci, but spores are narrower and he didn't report anything amyloid in excipulum. I appologize for the terrible micro. Unfortunately I had to work with exsiccate and without stereo microscope I failed to cut better samples freehand from such a small asco. Thank you for any advices. Viktorie

Parmi les Orbilia

Voici un petit champignon qui me cause bien des ennuis. Habitat : sur la face inférieure d'un fût pourrissant d'épicéa, Réserve de la Glacière, Esserval-Tarte, Jura, 850 m, parmi les Orbilia delicatula. Hymenium blanc, surface externe brun noisette très pâle, chair élastique ayant tendance à rosir dans la vétusté. Asques 85-100 x 9-10 µm, J-, pas trouvé de crochets, octospores Paraphyses dépassant les asques, peu renflées (2-3 µm), à contenu légèrement réfringent au sommet. Spores elliptiques fusiformes, hyalines, lisses, contenant deux gouttes avec d'autres plus petites moins évidentes, 8-10 x 4-4,5 µm. Chair élastique (pas pu en faire de coupe....) à côté, la même espèce présentait des tons et un hymenium plus brunâtres et à côté encore, hyménium bleu verdâtre et surface externe brune avec marge plus claire. Même micro pour les trois formes... A n'y rien comprendre. Aucune idée et je ne sais pas où chercher. Je joins une fiche micro rapide et quelques mauvaises photos mais pas pu faire mieux. Désolé. Si vouspouvez m'aider.... Grand merci Gilbert

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.

Cyathicula-like ascomycete with textura oblita, on wood

Hello, found today and at first glance taken for a small Mollisia, but minutely stipitate (seen only under dissecting microscope). The fresh apothecia have a very faint greyish-violaceous hue, so that Ascocoryne or Ombrophila would be fitting macroscopically, though apothecia are only apr. 1 mm in diameter. Asci without croziers, deep blue IKI reaction (Calycina-type I suppose) Paraphyses cylindrical, with one cylindrical vacuolar body appr. 20-30 µm long, medium rfractive, strongly stainied by IKI Spores fusoid to long-elliptic, hyaline, without septae, oil content 5, appr. 25 x 7 µm Ectal Excipulum a textura oblita from stipe to cup margin, ending in cylindrical inconspicous protrudings with the same small vacuolar body as the paraphyses. Scattered on bare dead wood of a Salix caprea stem Any hints welcome :-) thank you and best regards, Andreas

Tiny 'Helotium' on Eriophorum angustifolium culms

<div>Hi!</div> <div>These tiny (1-3 mm diam) stalked apothecia were growing on Eriophorum angustifolium culms in a very wet place (submerged), 850 m alt. in Norway. Hymenium flat or slightly convex, stipe with a slight pinkish hue. No sclerotium or stromatised tissue, so I guess not Sclerotiniaceae.</div> <div>Asci 65-80 x 7-9 micr, IKI neg. No croziers seen. Paraphyses ca. 5 micr broad, filled with slightly yellowish guttules. Spores 19-25 x 3-4 micr, fusiform, often bent, tending to form a lump at the ascus upper half and released as such. All photos from fresh material, mounted in water.</div> <div>I am not even sure what genus this is. Does anyone?</div> <div>Thanks.</div>

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?

Niptera / Phaeohelotium ?

Hi again This is a small ascomycete of 3-4 mm, on beech (Fagus sylvatica) that was inside a stream. Biseriate with croziers asci, and the following reactions: * IKI: dark red * KOH + IKI: dark blue * Melzer: very weak dirty red * KOH + Melzer: dark blue Large 3-septate spores, sometimes with 2, slightly strangled in the septa: (19.5) 20.4 - 25 (28.6) x (4.4) 4.7 - 5.8 (7.3) µm Q = (3) 3.7 - 5 (5.6) ; N = 55 Me = 22.8 x 5.2 µm ; Qe = 4.4 Paraphyses thickened and pigmented at the apex.

Roseodiscus ?

Hello I am hoping for some advice about a discomycete I found on a moorland hill in Lancashire, England at c. 450m, on peat amongst bryophytes - mainly Ceratodon purpureus. I am out of my depth here because I usually study lichens, but I have considered Bryoscyphus, Discinella, Octospora and Ombrophila before finding myself at Roseodiscus formosus. A rough description: Apothecia pale pink, 2-5mm diameter with ± flat disc, tapering to a whitish stipe (overall height 3-4mm). Paraphyses c. 2µm wide, septate, not expanded toward their apices, sparsely branched. Asci c. 8µm wide (in KOH), 8-spored, with hemiamyloid apical ring (orange in IKI before treatment with KOH, blue after KOH), with croziers. Ascospores 0-1 septate, 11-18 x 3-4µm (in water), with lipid droplets. I think my only reservation is that the paraphyses in water appear minutely granular, at least in the living state, but the contents more or less clear in KOH, apart from what looks like an occasional lipid droplet. Any words of wisdom will be gratefully received. Best wishes Nigel

cudoniella

I think this is cudoniella clavus. What is the diverence between clavus var clavus? Sporesize 12,5-14 * 4-5. Seemingly on the ground but on organic debris (most likely juncus) In a damp area between juncus and polytrichum?. At first i thought it was a discinella because of its pinkish colour.

noir sur Castaneus

Bien malheureux de ne pas arriver au genre... Champignon érompant sur Castaneus, mais vieux, noir peut-être par l'âge. stipité à la manière des Ombrophila, gélatineux, 1cm de diam. Spores presque noires, 10-14 X 6 microns Paraphyses filiformes. Lugol net positif. J'avais pensé au départ à de vieux Ionomidotis, qui est fréquent chez moi, l'aspect était voisin. Puis à un Encoelia, mais c'est impossible en micro. Même si mon champignon est vieux, y a-t-il possibilité d'envisager un genre? Merci beaucoup d'avance jean pierre

Discinella lividopurpurea ?

Bonsoir. Je vous soumets une récolte effectuée en zone alpine, en compagnie de J.-L. Cheype, le 25/08/2007, au col de Balme (alt. 2195 m, Haute-Savoie), sur terre très humide (ruisselement). Elle a été déterminé, pour le moment, Discinella lividopurpurea. En consultant la littérature, je trouve néanmoins quelques points de divergences... Voici ma description (cf. PDF joint pour les caractères micros) : Apothécies d'abord sessiles, pulvinulées, puis turbinées, à hyménium plan, violet sombre à violacé livide ; surface externe violet sombre, presque noirâtre. Ø 2-4 mm Asques issus de crochet, 100-125 × 9-11 µm, à pore apical IKI- (y compris après traitement au KOH 4%). Paraphyses cloisonnées, hyalines, avec quelques vacuoles (?) non réfringentes. Spores elliptico-fusiformes à subcitriformes, (9) 10-12 × (4,5) 5-6 µm, hyalines, lisses, sans guttule, présentant parfois 1 septum. Présence d'un gélin ± adhérent dans l'excipulum ; présence aussi d'un pigment violet. J'ai consulté principalement Boudier (BSMF, 1888), Le Gal (Rev. mycol., 1938) et De Sloover (Rev. Cercle Bruxelles, 2002). D'après De Sloover, D. lividopurpurea possèderait des asques IKI+ et des spores un peu moins large, et il note la présence de granules dans les spores ; il me mentionne pas de septum. Boudier (1888) ne précise pas la réaction iodée des asques et donne une mesure de spores de 11-15 × 3-5 µm, moins larges que les nôtres d'après son dessin. La couleur générale est fauve purpurin (cf. Icones pl. 447). Dans la même publication, il décrit Discinella badicolor dont la planche est plus conforme macroscopiquement à notre récolte (couleur notamment) mais les données microscopiques, avec des spores plus petites et contenant deux gouttes au niveau des pôles, ne collent pas. Enfin, Le Gal (1938, p. 136), dans une très courte description indique des spores de 11-13 × 4-4,5 µm et les donne « finement grénelés » (sic). Si certains d'entre vous ont l'expérience de cette espèce, je serai heureux d'avoir plus d'infos. Nicolas

Ombrophiloid fungus on peat-bog soil

Hi to everybody: Yesterday we have seen this lenticular to pulvinate totally whitish ascomata up to 5-6 mm in diam. that grows on Eriophorum angustifolium old leaves (and ericaceous host too) on very wet acid soil. The ascomata are sessile on a very broad base and they are glabrous. The medullary excipulum has a loose textura intricata without crystals that becomes very gelified at the cortex. I think the asci are IKI negative (or very faintly positive?). Croziers positive. The spores have a faintly gel sheath around them. I think is not an Hymenoscyphus species but I don't know a good genus for it What's your opinion?
