Hello everyone.
Substrate can not be able to determine so I place photos.
Regards

Both macroscopic and spores are very similar so I think you're right about the genre.
I did not know this species so far, I read a little about him in the literature to get more data, although it will only be pure formality because your type is very likely :)
thank you very much
Mirek

I'm not sure if the silver epidermis is ok for it, but Alnus has such a triangular pith.

Hi,
And perhaps could Norbert check the one on Quercus to compare to F. parafenestrata ?
Hermann, when we meet a such fungus on Quercus, is it possible to distinguish F. fenestrata end F. parafenestrata basing to morphology ?
All the best,
Alain
Yesterday evening I read the article indicated by Alain and I came to the conclusion that this must actually be F. Fenestrata.
However, she wondered the small width of spores in my collection Although the author of the quoted publication mentioned that the collections were studied strongly mature.
The comments contained in the article indicated by Hermann, explain my fears. It follows that the width of spores varies significantly depending on the tested collection. In that case, the width of my spores is within the right range.
Once again, thank you very much and greetings to all.

I'm coming back to the topic because a few days ago I found a very similar fungus but on another substrate and with a bit other spores. I do not assume a new thread because the collection is very weak, so I did not even do good photos. They grew on the Carpinus betulus. Spores of the size match Fenestella parafenestrata but I have not heard about this genre on Caprinus. Similar, but slightly smaller spores have F. media that occurs on such a substrate.
Apicule on spores occur rare.
Spores:
(46.7) 46.74 - 50.7 × (15.8) 15.85 - 18.7 µm.
Maybe someone with a greater experience will share an opinion with me?

It's again an unknown species.
A horrible lot of very similar species.
Thank you for identification!
greetings
