Coccomyces dentatus

Yannick MourguesBonjour 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

Nobody's surfing on Coccomyces vibration ?
Bad news for me !

I have this like C. dentatus, but I think the spores have not any septa, sorry.

Good luck,

Re:Coccomyces dentatus
Thank's Miguel.
Very interesting notes. Do you make same notes for all fungus you find ?
I think for mine that when spores become overmature, seta appear.
Amitiés.

Hi Yannich

I wish I had time to make that of all species I find, but I have not enough time, I make only the most interesting or rare for me. You can see another ones here (not only mine):

Re:Coccomyces dentatus
Very interresting and nice photos !
Why have you written "Tatrae aff. dumbirensis" ? Where is the problem ?

Re:Coccomyces dentatus
Thank you Yannick
Because the color and the margin shape. But really the micro fits Ok, I think.
If you have no doubt this is T. dumbirensis, I will change it.

Re:Coccomyces dentatus
Bonjour Yannick,
Voici un extrait de ma clef publiée il y a quelques années:
"Apothecia up to 1 mm diameter, black covering layer splitting up into 4(-5) regular teeth. Asci 70-105x8-10µm. Spores 0(1,3)-sept., 45-65x2,5 µm, both ends filled with small guttules, OCI=3. Paraphyses with straight clavate tip. On bleached spots on fallen leaves of Castanea sativa, Quercus robur and Quercus rubra. Summer and autumn.
Coccomyces dentatus (Kunze & Schm.) Sacc."
Spores à cloisons donc parfaitement acceptable.
Amitiés
