Bonjour à tous, je viens vous demander votre avis concernant une récolte du Genre Cryptodiscus et dont les ascospores ne correspondent pas à ce que je vois dans la litérature. J'aimerais savoir s'il existe une publication traitant sérieusement de ce Genre. Ascospores 40-45 mostly 42 x 5-6 (10)µm, 6-8 cloisons mostly 7 les deux cellules terminales plus claires, bisériées à multisériées Asques cylindriques à clavés 100 x 12-14µm, octosporés à tetrasporés Merci de votre aide, Amitiés,

Someone knows about that Coccomyces. Asci I(-), 160-186 x 12-15, with croziers. Spores needle shape, 64-87 x 2.5-3, occasionally twisted, no septated (inamatures ?) . Paraphysis not enrrolled, clavate, up to 7 broad. Thank you for your kindly help.

Hola a todos. Me gustaría saber si alguien conoce algún Coccomyces. Lo hemos recolectado sobre hojas de Laurus nobilis. Las medidas esporales son de hasta 92 x 2,8 micras. Generalmente la forma de ascocarpo es piramidal y en alguna ocasión cuadrangular, de 0,6-1 mm. Muchas gracias por anticipado. Saludos, Javier. Salut à tous. J'aimerais savoir si quelqu'un connaît un Coccomyces. Nous il avons récolté sur des feuilles de Laurus une nonbile. Les mesures esporales sont de jusqu'à 92 x 2,8 microns. En général la forme d'ascocarpo est pyramidale et dans une occasion quadrangulaire, de 0,6-1 mms. Merci beaucoup par anticipé. Des saluts, Javier. Hola to all.

Merry Chrystmas I have see this before now in a book or the internet , but I don't remember where. Living at Laurus azorica or L. novocanariensis leaves. Thank's in advance Miguel Ángel Ribes

Hello I though I was picking some Tympanis and put the specimen aside in a plastic bag and forgot it there for a week. Now when I had time I decided to try to determine it. I got supriced, because it had opened and looked like Coccomyces. It wasn't and seems to represent a genus unfamiliar to me. The spores seems to have or not to have a cover and are about 25-35x 10-15 with cover and about 25x3-8 without. Asci about 150-250x20-25 micrometers. The fruitbodies are 1-2 mm wide.

I have this 1-2 mm red apos. It seems like Mollisia obscura with red hymenium, but the micro is very diferent. http://dl.dropbox.com/u/5986266/Fichas%20dudosas/Coccomyces%20221109%20146.pdf Thank you

Quelque chose qui ressemble à Terrya pini, de 1,5 à 2mm de diam, enveloppe noire éclatant, montrant l'hymenium gélatineux jaune. Spores étroites apparemment non septées, hyalines, 30-35 x 1-1,2 microns, un peu courbes, avec quelquefois comme une boule de gélatine à une extrémité, peu visible. IKI négatif. Si quelqu'un connait les Weymouth et si mon champignon est spécifique de ce pin.... Merci de vos avis. Je l'ai trouvé en compagnie d'Alain Gardiennet, mais je ne sais pas s'il l'a récolté, il était occupé à côté... Au plaisir jean pierre

Bonjour à tous. J'ai une récolte de Coccomyces dentatus qui me pose question en ce sens que j'observe des spores avec 1 voire 2 cloisons. A part cela, tout correspond avec cette espèce. Ma maigre doc sur le genre ne me dit rien sur ces cloisons (en fait il semblerait qu'il n'y en ait pas). Avez-vous des infos là-dessus ? Merci par avance. Yannick

Hello, this should have been a breakable mystery, but I had no luck with this, too :( These are about 0,5-1mm wide and grew on Pteridium remnants,

Wondering if an ID to genus is possible from this photograph alone, no microscopy.  Any and all input is greatly appreciated.<br /><br />Many thanks in advance,<br /><br />-Danny

Hi,<br /><br />finding something new causes difficulties in determination, as now with this 1-2 mm wide asco.<br />The spores are about 50-70x2 and asci 110-130x10-14.<br /><br />Help is more than welcome: Marja

Sorry for the long post, it just shows that there is ambiguity with id ).<br /><br />There are several other Lophodermium's from ericaceous hosts, which identification doesn't get clear results so far. They from leaves of Andromeda polifolia, Ledum palustre, Chamaedaphne calyculata and Oxycoccus palustris. I checked SMML db for the hosts, it showed next records: for Ledum (diff. species) Lophodermium maculare, L. orbiculare, L. sphaeroides; for Chamaedaphne - L. maculare, orbiculare; plus Minter (Fungi of Ukraine, Rhytismatales) reports  for Andromeda polifolia - L. intermissum; for Ledum - L. sphaeroides. <p>I studied a monograph for the genus by Tehon (1935), but he omitted several of those substrate-selected species since the types difficult to study (intermissum, sphaerioides, as well as oxycocci are excluded from this monograph).</p> <p>Following the key, then, all my specimens go to Lophodermina (hysterothecia subcuticular). Specimens collected from Ledum, Andromeda, and Oxycoccus leaves were identified as L. melaleucum. But spores in mine are shorter. I assume, all these specimens collected from different hosts are one species; but i noticed also differences in paraphyses shape in Ledum collections. The type description of L. intermissum (from Andromeda) also fits with these collections. L. orbiculare has larger spore size. Good description of L. sphaeroides i was not able to find.</p> <p>Collection from Chamaedaphne goes to L. autumnalis (reported in monograph for Abies). Beside host, construction of labile also differ; but my specimens were underdeveloped and observations could not be done completely. It is clear that it is another species (with much larger spores and asci comparatively with previous), and it was collected only from Chamaedaphne.</p> <p>The last specimen turned to be Coccomyces, and description of C. duplicarioides (Sherwood, 1980) matches it well (also from Andromeda host).</p> <p>There they will be posted, for the case if someone may help/be interested in further processing. Probably, i am missing also recent related monographs. Fresh collecting will be help too, i think, as these were not always in full size and color.</p> <p><em><strong>Lophodermium cf. melaleucum or intermissium</strong></em></p> <p>On upper and lower sides of dead leaves of Andromeda, Ledum, Oxycoccus.</p> <p>Collection from Andromeda:<br />Hysterothecia ellipsoid to circular,  up to 0,6 mm, subcuticular, margin elevated (up to 200 mk high), operculum ellipsoid to circular, edge with yellowish (or hyaline, probably underdeveloped), hymenium gray (once yellowish), outer surface black.</p> <p>Flanks from textura epidermoidea; pallisade layer well developed, light yellowish-brown, from prismatic arranged in columns cells (glued together), up to 5-6 cells in each column (30 x 5 mk); asci clavate, clamped, inamyloid, 79-88 x 6,4-10,2; paraphyses filiform, larger at base (2,5), about 1,5 mk otherwise, with many small guttules, circinate at upper part; spores needle-shaped, 24 (21,5-26) x 1,3 (1,1-1,5) (N=12).</p>

Good time to everybody).<br /><br />I have mentioned earlier this species, but now it is with vital description. It fits well with description in Sherwood (1980,Taxonomic studies in the Phacidiales: the genus Coccomyces (Rhytismataceae).<br />It is described in this publication based on collection from Magadan Region (Far East, Russia), and reported there to be the species with unknown describution.

Hi everybody,<br /><br />This is a <em>Coccomyces</em> that was growing on dead leaves of <em>Q. ilex</em> subs. <em>rotundifolia</em> and <em>Q</em>. <em>coccifera</em>, in eastern Spain at around 200 m asl.<br /><br />Following a key shared by B. Declercq here in Ascofrance, I'm not quite sure if my specimens belong to <em>C. dentatus</em> or <em>C. coronatus</em>. Macroscopically, they are more related to the former, microscopically to the later though. Perhaps there are other "intermediate species" which weren't included in that key. <br />Some of the traits that could help to identify it are:<br /><br />- <strong>Spores</strong> 63-87 x 2'5-3'3(4) um, with one rounded end and the other somewhat sharpened, abundant granular content.<br /><br />- <strong>Asci</strong> between 95-120 x 9-11 um.<br /><br />- <strong>Paraphyses</strong> with more or less clavate tips, straight or slightly curved, surrounded by gel and 3-4 um width.<br /><br />- Macroscopically, there can be seen 3 to 5 black, irregular teeth. Ascocarp diameter not exceeding 1mm diameter. Hymenium whitish to ivory. Despite I've not studied it yet, there are some black, smaller dots around the ascocarps that could be pycnidia.<br /><br />Any suggestion will be appreciated!!<br /><br />Cheers<br /><br />Isaac

Dear colleagues, I have a question with identification of some taxa from litter of <strong><em>Andromeda polifolia</em></strong> (West Siberia, near Khanty-Mansiysk town). We have a  manuscript on fungal consortium of this plant in a bog, and I like to invite a specialist as a co-author for identification of following morpho-species (39 taxa totally). I have posted some of them already in forum, and others will do. But probably someone will be interested in systematical work with the collection in collaborative way.

Hello forum,<br /><br />when these black spots open, they show their yellow hymenium.<br />They grow on Vaccinium uliginosum leaves and are a bit under 1 mm wide.<br />The spores are about 65-85x2-3, asci 140-160x12-13 and paraphyses about 4 micrometers wide.<br /><br />Once again my litterature does not contain a species with these properties or the species is not a Coccomyces at all.<br /><br />Marja<br />

<p>Hello,</p> <p>Coccomyces dimorphus, described by Liang et al. (Mycosystema, 19(1), p. 3-6, 2000),<br />has two types of asci (normal cylindrical and lanceolate) in a ascocarp.<br />Does anyone know other discomycetes having such dimorphic asci?</p> <p>Kutsuna</p>

<p>Hi again</p> <p>What about this Sporomega/Colpoma growing on dead wood of Cistus ladanifer lying on the ground at the SW Spain?</p> <p>The ascospores are 1-septate with a gel seath and an apical globule. Paraphyses with conspicuous Vbs stained blue by Cresyl blue. No yellow KOH reaction or only greenish on the dark, marginal, elements. This collection agrees with Guy Garcia's GG 04040402 and GG 05041001 from 2004 and 2005 on Calluna and Castanaea wood. But my spores are only 1-septate (not 3-septate) and lacks de yellow KOH reaction (saids 'as some Mollisia species').</p> <p>Do you now some news on this fungus?</p> <p>Thanks again</p>

Color of fungi : green &amp; black.<br />This needle on top of Fagus stump and then covered with thick layer of moss. There for many years.<br />Loc.: Slovenia.

I thought I would share this picture here and see what spp. people think are present.  Corresponding Mushroom Observer post at http://mushroomobserver.org/238464.  Any IDs made here will be added to the observation.<br /><br />I see at least seven spp.:<br /><br />1 ?<br />2 Lophodermium (L. minus?)<br />3 Lophodermium sp.<br />4 Coccomyces sp.<br />5 Coccomuyces aff. clusiae<br />6. ?<br />7. ?<br /><br />I realize that most of these will never be identified without microscopy.  I hope to be able to provide some photomicrographs on all of these someday soon.  In the meantime, I appreciate your input.<br /><br />Many Thanks!

<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>

Hello all,<br />Earlier this week I found this orange erumpent asco on bare hardwood which I thought might be Coccomyces or Colpoma. But microscopically it resembled Propolis sp. Spores are 23-29 x 7.5-8µm. Asci IKI-. The paraphyses branch toward the tips. It was quite confusing until I discovered the discussion between Jonathan M and Zotto here http://www.ascofrance.fr/search_forum/48605.<br />Perhaps my collection is also Propolis farinosa?<br />Ethan

<div>Bonsoir tous</div> <div>Collected yesterday on damp dead <em>Vaccinium myrtillus</em> stems in a relatively small area of <em>Calluna</em> / <em>V. myrtillus</em> / <em>Molinia</em> moorland.</div> <div>Interestingly, this site is less than 5 kilometres away from the first collection of <em>Micropeziza filicina </em>(see <strong>Ascomycete.org</strong>, 5 (4) : pp.129-136) but it is clearly not that - a very different substrate and larger ascospores - 13.9-15.7 x 4.6-5.2µm. I know that other <em>Micropeziza</em> spp. have been recorded on Ericaceae, but those were (as far as I am aware) on <em>Rhododendron</em> leaves.</div> <div>An interesting feature is that the freshly ejected ascospores have a sheath - clearly shown in the accompanying images. I'm fairly certain that this is a <em>Micropeziza</em> based on the encrusted excipulum, <em>Calycina</em>-type ascus apex (strongly blue in Baralsche Löhsung), and other features.</div> <div>I wonder whether this might be undescribed? Any comments very welcome - I shall post more images in due course; as you can see the collection is in good condition.</div> <div>Cordialement, Chris</div>

<br />Hi.<br />It will probably be an easy puzzle for you, because if I am not mistaken, I have already watched something like that, but now I cannot associate it.<br />I am posting some photos and counting on your help.<br />Thank you in advance and best regards.<br />Mirek

Hola amigos:<br />Hace un par de dias recolecte sobre estrobilo de piña (<em>Pinus pinea) </em>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.<br />Aunque muy parecida por el aspecto macro de <em>Coccomyces strobi</em>, 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.<br />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.<br />Me gustaria saber si alguno teneis alguna idea de cual puede ser la especie en cuestion.<br />Muchas gracias de antemano.<br />

I though I'd just ask you about this tiny discomycete, which I struggle with. It is only about 0.2-0.4 mm in diameter. It was growing on a<em> Populus tremula</em> log, directly on the wood. The wood is hardly decomposed and very firm. It was collected last May, but I only recently received the dried specimen. It seems like the hymenium in many of the apothecia are now eaten by insects or have decomposed. Thus quite difficult to make nice, thin sections, so I apologise for that.<br /> <p>I am not even sure what family we're in. Initially, when I saw it in wet condition, I thought it was erumpent and was thinking Coccomyces or along those lines. Indeed some of the younger ascomata appear to be erumpent, but in the dried material I see that the dark-rimmed, somewhat dentate apothecia are sitting directly on the wood, anchored by a fringe of white hyphae (anchoring hyphae/subiculum). The hymenium is, when fresh whitish, when dry more greyish and somewhat pruinose.</p> <p>The spores measure 12-15 x 5 microns, mostly 3-septate, hyaline, smooth. Some spores are smaller (7 x 4) and 1-septate. Many spores are germinating from one or both ends – I guess the specimen is over-mature. What I think are paraphyses are orange-tipped (irregularly flame-like). There are dark, transversely roughened hyphae in the excipulum (fringe) and some spherical cells in what may be subhymenium. The ascus tips are IKI+ (blue in Baral'sche Lösung with no KOH pre-treatment). Structures in the excipulum are stained greenish-blue with IKI, too, but I am not sure that it's due to amyloidity.</p> <p>Here's a link to some photos. Photo names indicate the medium (KOH, IKI, PC (phase contrast)).</p> <p>https://www.dropbox.com/sh/4prdmaszwi682ys/AABEAjm33Pf5d4b0lAUx0cnLa?dl=0</p> <p>The best fit is in the genus Heterosphaeria, but I'm not sure if any species in that genus grows on wood.  Are we in Phacidiaceae?</p> <p>Suggestions appreciated.  Thanks!  (I hope the link works)</p>

Bonsoir à toutes et à tous<br /><br />Ces spécimens de Rhytismatales ont été trouvés sur une petite branche morte d'un épicéa à aiguilles bleu-grises à Bellac (87300)<br />Mes recherches ne m'ont pas permis d'accéder à une certitude sur le genre (Colpoma, Therrya, .....) et encore moins de l'espèce.<br /><br />Pouvez-vous me renseigner à l'appui des clichés ci_joints<br />  - les apothécies ont un diamètre de l'ordre de 1 à 2 mm<br />  - les asques sont clavés dans la partie supérieure et longuement étroites dans la partie basale<br />    (120 -130 x 10 µm<br />  _ les spores mesurent : 35 - 50 x 1,5 - 2,5 µm, donc allongées et très faiblement fusiformes avec un bout plus obtus et souvent coiffé d'une gaine gélatineuse et l'autre extrémité un peu effilée<br /><br /> Merci d'avance pour votre contribution

Hola a todos.Subo unas fotos de un asco que encontramos el sábado pasado sobre corteza de Pinus sylvestris.<br />Miden alrededor de 1 mm de diámetro.<br />Esporas de 100-150 x 4,5-5 micras.<br /><br />¿Qué les parece?<br />Gracias por su ayuda.<br /><br />Rubén

Bonjour, <p>Sur branche morte de Pinus cembra en position aérienne (à '~2000 m).<br /><br />Apothécies 0.75 - 1.5 mm de diamètre, Ascospores (eau) : 17 - 25 x 2.5 - 3.5 µm, aseptiques, hyalines, lisses. Asci : 112 - 165 x 7.5 - 10 µm, octospores, rétrécies à la base, avec crochets, non amyloïdes, paraphyses filiformes et spiralées à l'extrémité.<br /> <br />Je pense que cette espèce est Parvacoccum pini. Merci beaucoup pour vos commentaires.<br /><br />Elisabeth</p>

<div>Hello,</div> <div>Found 24 June 2023 on dead leaf of Quercus rubra.</div> <div>Apothecia 1 mm</div> <div>Asci, Me: 109.6 x 8.9 µm, N = 3</div> <div>Spores (largest ones): 52.3-58.1 x 1.8-1.9 µm</div> <div>Is this Coccomyces dentatus?</div> <div>Greetings, Riet</div>

Argañoso (León) SPAIN at 1200 m altitude, on an oak leaf, new to me.<br />Specimen of just over 1 mm. Meltzer negative in apex ascus .<br />Spores measured in water:<br />(49.1) 51.9 - 75.5 (76.5) × (1.7) 2 - 3 (3.3) µm<br />Q = (17.3) 20.6 - 31.9 (37.3) ; N = 23<br />Me = 65.6 × 2.6 µm; Qe = 26.3<br />I don't know if you can know the species<br />Thanks and regards

<div>higher resolution images available at inaturalist.org/observations/179449419.</div> <div>Trochila initially suspected, but microsocpy seems to contradict this.</div> <div>Attempts at rehydration to open potentially hygroscopic apothecia was unsuccessful.</div> <div>Stage micrometer was recently lost, and so sadly I have no measurements at this time.</div>

<div>Diam 1 mm, on a fallen leaf of Quercus coccifera</div> <div>asci 107-144 x 6,5-6,7</div> <div>spores 57 [62.7 ; 74.2] 79.9 × 1.4 [1.6 ; 2.1] 2.4 µm</div> <br />

Pourriez-vous m'aider à identifier cet asco noir sur feuille pourrie de chêne ?<br /><br />Grand merci d'avance !<br /><br />Bernard

Bonjour ! Je travaille sur mon mémoire de master sur la diversité des macrochampignons et nous avons trouvé ce spécimen lors d'un échantillonnage. Nous ne sommes pas sûrs de quelle espèce il s'agit. J'apprécierais toute aide !<br />
