Vexillomyces atrovirens? => probably V. munathinus

Hello,
Found by Laurens van der Linde, March 2023, on Quercus.
Is this Vexillomyces atrovirens?
- apothecia 0.5-2 mm
- not ionomidotic
- IKI-
- ascus with crozier
- ascoconidia 2.5-3 x 1 µm
- primary ascospores more than 7-septate, 20 µm long
Greetings, Riet

Re : Vexillomyces atrovirens?
The ascoconidia are rather allantoid and the ascospores cylindrical and seemingly without longisepta, so it is clearly not atrovirens. I assume the specimen is from NL. So it could be V. hydnicola or V. munathinus, the latter being the probable choice. It likes to grow together with Dacrymyces.

Re : Vexillomyces atrovirens? => probably V. munathinus
Stip, you do not have our old Claussenomyces.key? Guy used munathina, and I assume that is more correct because it is an abbreviation for something like museum nationalis thi... naturalis.
