Re : Grey Pyrenopeziza/Mollisia on Quercus
This must be a Mollisia in bad shape. Depending on the apo size it could be M. olivascens or M. elegantior. You saw any asci and paraphyses?

Thank you for your reply.The largest apo measured 0.7mm.
I added some extra pictures of the asci and the paraphyse.
Mollisia olivascens?

Re : Grey Pyrenopeziza/Mollisia on Quercus
M. olivascens is much larger, maybe 2-3 mm. So this is a Mollisia I cannot further identify.

The VBs are nicely seen. The apical rin seems to react reddish? - which would be unusual.
