Good evening,another quite distinctive find from March on a log of Fraxinus in the gorge:
The spores are quite variable in shape and have [ 12.8-14.7-17.6 ] x [ 3.8-4.4-4.9 ] Q = [ 2.7-3.4-4.1 ] N = 13. Asci 8 spored, uniserate, IKI-, Paraphysis 1.5-2.5 thick
Thank you very much for help!

Re : pyreno on Fraxinus
Hi, Andreas!
It reminds me of Biporispora europaea. Please check if the ends of the ascospores have germ pores.
Best wishes,
Gernot

Hi Gernot,
thank you for your answer!
Pictures are not very good, however I think that the middle spore on top look like a pore.
Try to find the exsicate for better docs...

Re : pyreno on Fraxinus
Hi Gernot,
found exsiccate and made some pics from spores and dissolved Stroma in KOH 30%.
Asci measurement [ 91.3-98.7-104.1 ] x [ 5.8-6.2-6.6 ] Q = [ 14.1-15.9-17.9 ] N = 6
The germ pores are hard to see, but I found some hints (see pics).
I think this fits very well to Stefan Blasers post

Re : pyreno on Fraxinus
There are indeed pores visible, yes. I think it looks good for Biporispora europaea.
