Albotricha/Dasyscyphella?
Juuso Äikäs, 08-07-2020 20:29
These were growing on a dead grass stalk in a forest.

The outer hairs are long, smooth and tapering towards the end, with some exudate. The asci didn't appear to have croziers, ascus pore blue in Lugol's solution. Paraphyses lanceolate. 

Spore measurements:
(9.5) 10.8 - 16.4 (17.8) × (1.7) 1.8 - 2.2 (2.3) µm
Q = (5.3) 6 - 7.8 (8.7) ; N = 15
Me = 13.7 × 2 µm ; Qe = 6.8

I'm pretty sure that this is either Albotricha or Dasyscyphella. Maybe A. acutipila or D. caduca?

Re : Albotricha/Dasyscyphella?
If the croziers are absent it seems acutipila, though I would have suggested caduca which has croziers.

A difficult case, both species are genetically in Albotricha.

Ok, I think I'll re-examine the sample in congo red and see if I missed something.

Re : Albotricha/Dasyscyphella?
I checked the sample again and it seemed to be quite clearly without croziers.

Very clear! I am not sure if the croziers are also verified in the type specimens of these species, but in the concept I know it seems an important difference.
