Pyrenopeziza on Filipendula ulmaria

Juuso Äikäs, 09-06-2022 14:41

I've seen this fungus many times before, and it seems to be quite common and plentiful on dead stems of Filipendula ulmaria. This is a finding from yesterday, found near shoreline.

Spores slightly clavate, measuring 8.9 - 9.9 × 2.1 - 2.5 µm, OCI = 1.

The asci measure 42.3 - 56.5 × 6.6 - 7.3 µm, with croziers, IKI+(bb).

Paraphyses +- cylindrical, some a bit swollen. No hairs.

I assume this is a Pyrenopeziza, and maybe someone knows the species?
