The only thing I can say about it is that it is definitely very resistant to difficult winter conditions. From mid-January there were severe frosts, down to minus 25 degrees Celsius at night. It wasn't until a week that the temperatures rose above freezing. Therefore, they must have grown already before the New Year. Despite such a long growing season, they were in excellent shape.
Help in determining the species is appreciated!

Q = (4.6) 4.7 - 6.2 (6.4); N = 7
Me = 18.9 × 3.5 µm; Qe = 5.4

Re : Little asco on pine wood?
Yeah Stip, that was my idea also. I only wonder about the ascus base, doesn't that species have croziers?

Hi Stip and Zotto
Now I even associate it with something :)
I looked at the Zotto disc (Hyaloscyphaceae), but there are so many species on it that I ran out of patience. I was even in the Pseudohelotium catalog, but I gave up and preferred to ask in the forum.
Thank you so much, you saved me some time.
It was hard for me to associate because I only knew Pseudohelotium pineti ... thanks to you I already know two species of this genus.

Zotto, sorry for posting such a blurry picture of the ascus base. You don't actually see croziers on it.
Croziers is present!
