Diatrype on Carpinus betulus

Mirek Gryc, 16-02-2022 09:48

Hello all
My experience in this topic is small so I would like to ask you about your opinion.
I found Diatrype on Carpinus betulus. Features lead me to D. stigma or D. subaffixa.
In my opinion, More Fits D. Subaffixa? Ostioles D. stigma should be less convex.
Is my diagnosis correct?
... or maybe some other genre?
Spores:
(8) 8.1 - 10.7 (11) × (1.9) 2 - 2.4 (2.5) µm
Q = (3.5) 3.7 - 5.4 (5.6); N = 17
Me = 9.6 × 2.2 µm; QE = 4.5
Ascus: J +
greetings
Mirek
