Me recuerda al género Amaurodon (basidiomycota)

Saludos,
Carlos

agree - A. cyaneus is a possibility if you cannot find any clamps. The spores should be more blue in KOH
cheers

Hello Carlos and Thomas,

oh yes - you could be right. Always when I find a lot of spores and not too many other structures, I am seduced to think of an anamorph. I will re-examine and try to find basidia, and look the spores in KOH.

Thanks and best regards, Lothar

I was too fast here - yes, it is a "simple" basdiomycete, and yes, an Amaurodon. I come to A. viridis, the hyphae are clamped, and the spores are fitting.

Thanks again, and best regards, Lothar

Hello Ludo,

the structure of this Amaurodon is not at all ceraceous but quite filamentous, and easy to separate from the substrate and to pull apart into fluffy pieces. Structures similar to this you can easily find in anamorphs of ascomycetes.

Best regards, Lothar

Thank you for your reply Lothar.
I must be mistaken in what ceraceous refers to. I though it just refer to a 'waxy' appearance.

If I may reformulate my question: do you know any resupinate hyphomycete (asco) in which the sporulating surface is organized like a hymenium? I know it wouldn't qualify as a 'hymenium' in the absence of meiosporangia, but I wonder what, other than setae, may represent sterile hyphae intermingled with conidiophores/ conidiogenous cells in 'resupinate' ascos?

Cheers,

Ludo
