Peziza fimeti or Peziza bovina
Wim de Groot, 03-04-2024 22:20
I am not sure which Peziza this is. On cow dung, dune area north sea coast, apothecia 1-2cm, spores (n=10) 19,1 x 10,7 µm (17,4-20,2) x (10,4-11,2) µm, spores with no drops, asci lenght 250 µm, parapyses slender 3-5 µm wide with slightly swollen tips, asci top blue reaction with Melzer's. I do not have a recent Peziza key.

No macro picture?
The only thing I can say is you're right about the genus.

Re : Peziza fimeti or Peziza bovina
The presence of yellow guttules in the paraphyses is a character shared by P. vesiculosa and P. fimeti. The spore size is a bit larger in P. vesiculosa and apothecia are bigger. So I think your collection corresponds to P. fimeti.
