Orbilia "trechispora"?
Przemyslaw Drzewiecki, 01-12-2022 23:50
30.11.2022; Mochle near Bydgoszcz, Poland. Old horse pasture fence post. (Pinus sylvestris). Not so many.
I thought it was Orbilia xanthostigma, but the appearance of the ascospores did not fit this kind of completely. I therefore ask for aid in determining the species of the fine.

Re : Orbilia "trechispora"?
This is O. xanthostigma anyway. The curvature of the spores may sometimes be only slight, but we rarely saw such cases. Then the spore is especially thick.

Re : Orbilia "trechispora"?
Thank you for clearing my doubts. I would say that here the curvature of the spores is rather exaggerated. :-) In the microscope slide, I saw conidia that do not match these Orbilia. Are they alien?

For those interested, I've attached last year's photo of typical O. xanthostigma ascospores.

Re : Orbilia "trechispora"?
Yes, these are typical ascospores. The conidia might be orbiliaceous but not belonging to this species.

Thank you again. It's great to get the opinion of a real expert. Greetings from Poland
