anamorph on wood and leaves

... under a twig of deciduous tree (likely Quercus or Carpinus) on the ground in a decidous mixed forest on acid soil - in the National Park of Eifel, Germany, 13.11.2019.


I found the macroscopical appearance quite striking - and so I hope somebody can provide me with a hint. The conidia are bluish and distantly warted, about 4,8-5,5 µm.


Best, Lothar

Me recuerda al género Amaurodon (basidiomycota)

Saludos,

Re : anamorph on wood and leaves
agree - A. cyaneus is a possibility if you cannot find any clamps. The spores should be more blue in KOH
cheers

Re : anamorph on wood and leaves

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

Re : anamorph on wood and leaves

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

Re : anamorph on wood and leaves — tangential question
I would like to know more about 'resupinate ascomycetes'.

Are there any ascomycete producing ceraceous and resupinate structures like that one (I understand it has been identified as Basidio)?

The only asco I know of that may vaguely look like this is Ascocorticium anomalum, and it is not really as tuberculate.

Cheers,

Ludo

Re : anamorph on wood and leaves

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

Re : anamorph on wood and leaves
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
