Hello, bonjour.Here is the paper I'm searching for
Pyrenopeziza on Filipendula ulmaria
Juuso Äikäs,

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?

Hi Juuso

Thanks Enrique, this seems like a good suggestion! The substrate, appearance and microscopy all seem to fit.
