Nice, small asco, growing on dead stems of Helianthus tuberosus. Slightly immature but I have already seen a few spores. I have already found a lot of Asco on this substrate but I do not remember it yet. I hope you help you determine the species. I keep them alive, so if necessary I can take more photos. Marginal hair with content but not reacting with both KOH and Lugol.
Greetings to everyone

@ Lothar.
I wasn't sure if it's not Olla but I don't know such a species. Hyalopeziza in the title was a complete blind shot but nothing more reasonable I could come up with.
@ Zotto
I will review your catalog in the evening. Now I am at work and I am not logged in to Google on this computer (I don't remember the password).
However, I can see that this is this species: D
Ah, are you saying that the black ones are associated with this species?
Thank you very much
Mirek


I can remember a collection of P. lanceolatoparaphysatum on Heracleum and mostly on Chaerophyllum .
Looking at my pics, I realize that I didi not notice such an anamorph on the substrate. DId I actually overlook it ?
I attach plates showing macro and micro features , including the IKI reaction on excipulum cells
Another point is that contrary to other specis in genus Psilachnum, I could not observe here the usual Psilachnum guttule in the ascus base .
The surface cells are also remarquable in CRB...
