Pyrenopeziza betulina?
Juuso Äikäs, 12-05-2020 21:36
I visited a small, swampy forest today and found something growing on a fallen leaf of Betula. In the field while looking at them with a hand lens I thought they were Orbilias of some sort. But soon I suspected that they are Pyrenopezizas. I think the microscopy agrees with this, although this is the first example of that genus that I've inspected. 

The spores measure 11-15.3 × 3-3.3 µm. Given the microscopy and the substrate I suspect this might be P. betulina (same as P. betulicola, I believe). Am I right?

Re : Pyrenopeziza betulina?
Yes, I think there is no doubt.
