Small asco on pine wood?

Several creamy sporocarps quite small. Maximum diameter up to 0.7mm.
The outer surface of the fruiting body is composed of brown cells. At the base of the sporocarp, more oval, gradually lengthen up to the margin where they form fairly long cylindrical hair.
Hyaline paraphyses, filiforms, slightly widened at the top.
Spores without content:
(6) 6.1 - 7.1 (7.3) × (3.1) 3.2 - 3.65 (3.7) µm
Q = (1.6) 1.8 - 2.1 (2.2); N = 12
Me = 6.8 × 3.4 µm; Qe = 2
6.94 3.60
7.11 3.61
7.12 3.34
6.84 3.39
6.93 3.65
6.33 3.06
7.07 3.34
5.96 3.65
6.14 3.34
6.66 3.19
7.30 3.27
6.88 3.44
No idea!

Hi Zotto
If I understood correctly, even the genus is unclear?

Pezicula ?

Re : Small asco on pine wood?
Surely no Pezicula which has large oil-rich spores.
Genera are constructs, and it is often much easier to identify a species than a genus (sometimes it is reverse). In this case I cannot even say which species might be related.

Re : Small asco on pine wood?
And that's why I love my Knyszynska Forest!
It still surprises me with its richness :)

Of course, I will keep the sporocarps. If they are interested in someone, they will be happy to share. Personally, I have no possibility of more accurate research (sequencing).
Thank you!

Re : Small asco on pine wood?
Hello,
What's the status of the sample? Still fresh and alive? If you have the possibility to send fresh material I could try to make a culture. And if this turns out to have affinity to Hyaloscyphaceae s lat I am especially interested in it.
How should I interpret the general structure of the ascocarp? Is that hymenia completely covered in hairs? - although you say the hairs develop at the margin. Could this have something to do with Polydesmia?? But maybe the resemblance is completely superficial.

Re : Small asco on pine wood?
Hi timo
Unfortunately, but the sample has already been dried. Most of the fruitbodies were already ripe so I was afraid to keep them alive.
I doubt they have anything to do with Polydesmia. I know this species and the microscopic structure does not resemble them at all?
The sporocarps are very thin so internal textures are difficult to observe. In principle, what could be shown is visible in the pictures.
I put some more photos showing the external surface and one more macro photo. The marked, white fruitbodies are something completely different, but I didn't have time to examine them.

Re : Small asco on pine wood?
ok!
seems I got a bit lost with the macrophotos. And I agree that it does not look like POlydesmia in the micros, and they are the better evidence here :-)
Still, the structure is curious.
