Hello I want to ask you if you have found this ye
Dear Forum,
On the bark of Quercus, I found some small pale yellow apothecia with pruinose aspect.
Asci were inoperculate and measured 65-72x9µ. The spores were 3-septate and contained a lot of guttules( 22-23x4-4.5µ). Some paraphyses were branched.There was a blue coloration of the apical apparatus with IKI.No conidia were seen.
Could this be Claussenomyces or rather Pezicula?

You are right Zotto, sporewidth was a bit overestimated. I again measured 15 spores and had a mean of 3.8µ.
It matches very well with your pictures in IVV.
Thank you very much
Marc
