Yellow asco.

Hello all.
A friend sent me this one dried fruit. After moisturizing about 2.5 mm. According to a friend's account, it grew on the ground, but there are also mosses nearby.
Almost all the traits fit Hymenoscyphus epigaeus (= Phaeohelotium epigeum), now rather Bryoscyphus?
However, I am puzzled by quite large spores, I measured a few:
Me = 16.9 × 3.8 µm; Qe = 4.5

18.19 3.50
20.35 4.46
14.33 3.58
16.31 3.57
16.86 3.71
15.16 3.78
As you can see from the photos, the spores are already septate in ascus.
Croziers (+)
Reaction to iodine fairly gentle but regular (BB)
Sorry for the bad quality of the photos, but it is difficult to get a clear image from hydrated material.
best regards
Mirek

Re : Yellow asco.
Oh, that will hardly be solved without vital characters. Spore septation has little to say as it usually occurs in overmature spores (only inside asci which are in dead state).

Phaeohelotium epigaeum I would exclude, more probable is P. monticola (or perhaps P. epiphyllum).

Re : Yellow asco.
Thank you Zotto!

Due to the substrate, I did not think about these species.

Probably you are right:)

In my case, H. epiphyllus, due to the constant lack of moisture, usually grows on decaying stumps or thicker pieces of wood. In wet weather, also on finer wood remnants and on bedding.
