Acervus?

Hello to everyone!
I find it difficult, to be honest, even with the genus of the fungus. While the it's fresh, I would like to understand what it is.
Fungus grows in the mountains in a mixed forest (mostly spruce) on a ground at an altitude of ~ 1800 m.
Apothecium 9 and 21 mm. Hairs 200-430 µm long.
Ascospores in water (on photo): (12.5) 13.7 - 15.1 (15.6) × (7) 7.3 - 8.2 (8.5) µm N = 100 Qe = 1.9

Spores in the water (out of asci) have an additional shell, which is destroyed in most spores. Therefore, it hasn't yet been possible to photograph the ascospores in lactophenol with preservation of this shell.

Re : Acervus?
Hello!
I think your fungus is rather a Cheilymenia species.
Acervus has smaller spores and no hairs.
Best wishes: Attila

Re : Acervus?
Hi
A few details do not suit me but maybe you can compare it with Cheilymenia vitellina?

Re : Acervus?
Attila, Mirek, thank you!
Indeed, Cheilymenia vitellina looks like a good candidate. However, there are some inconsistencies with the description of the referenced article and the article by Peric (2004). The size of the apothecium is larger, while the spores are smaller, and I did't see any striation either in the LCB or on dry spores.
What can you say about the areola around the spores? I have added photos of spores and asci in LCB, and section of the fruitbodie.

Re : Acervus?
Hi Vassiliy.
I do not know any other species with a similar appearance and microscopic features, so I proposed a comparison with this species, although as I mentioned, not all features match it. I meet this species quite often. It grows on humus soil, usually accompanied by nettles (Urtica).
So far, the largest that I have seen were up to 1 cm in diameter.
I haven't been able to observe the spore ornamentation yet. It is said to be hard to spot.
I cannot explain the presence of a gelatinous coating around the spores. Perhaps this is due to the old age of the spores.
If you have younger fruiting bodies, why not check if the spores look similar?
I don't have any more ideas.

Re : Acervus?
Hi Mirek.
Unfortunately, I found only two of these fruitbodies. They show the same picture. The first photo of ascospores in water from a small fruitbodie and photo in LCB from a large one.
Thank you! Nettle was present. Then, while I consider this fungus as Cheilymenia vitellina.

Re : Acervus?
Sometimes when the spores are overripe they don't look quite natural?
Here are two examples:
