With big spores? [Fenestella fenestrata]

Hello everyone.
Substrate can not be able to determine so I place photos.
Is anyone able to help me specify the genre?
Spores: Me = 58.1 × 17.3 um
Regards

Re : With big spores?
Hello Mirek,
sorry that I can't help you with the wood. But your species should be Fenestella fenestrata. I found it some years ago on small twigs of Quercus. Here are two pictures that you can compare.
Sincerely, Norbert

Re : With big spores?
Hi Norbert
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

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

Re : With big spores?
Thank you, Alain, for the link to this fantastic publication! I didn't know it until now. And I see there is one species named after you as its collector - very nice!

Re : With big spores?
Yes, also the bark looks like Alnus. Which is the type host of Fenestella fenestrata sensu stricto, for which the spores (large size, dark colour, subhyaline apiculi, very dense muriform septation) also fit well.
For a detailed description of Fenestella fenestrata sensu stricto, see https://www.sciencedirect.com/science/article/pii/S0166061617300489

Re : With big spores?
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

Re : With big spores?
Hi Alain,
ya, that's difficult... Spores of F. fenestrata are in mean larger than those of F. parafenestrata, and appear to be more densely septate (i.e. the cells appear smaller). But one also has to say that these species are rarely found (and probably uncommon), and therefore we didn't have enough collections at hand to fully evaluate the intra- and interspecific variability within these two species.
As with many species, reliable species identification may only be possible with sequence data in intermediate collections not fully showing these differences. And, there may be additional undescribed species around....
Best,
Hermann

Re : With big spores? [Fenestella fenestrata]
Hello everyone again and thank you for very valuable comments.
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.

Re : With big spores? [Fenestella fenestrata]
Welcome back.
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?
greetings
Mirek

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