Miguel Ángel RibesGood afternoon.Does anyone know this anamorph?It g
I recently found a species of Peziza on clayground in a young decedious forest.
Spores covered with fine wrats not forming a reticulate pattern; 2 distinct guttules; without distinct polar apiculae.
Disk not bleu; with violet tints
Parafyses with some brown pigment
Can anyone confirm or correct my supposition?
Thx, William
this reminds me macroscopically on P. michelii, but I cannot read the spore sizes and also bigger image of the ornamentiation would be useful.
For my own curiosity: what structure has the excipulum? Does it have medúlla of t. intricata, or is it only t. globulosa? I have some collections identified previously as michelii, macro ok, spore size + ornamentation ok, but they have two-layered excipulum, while P. michelii should have only t. globulosa throughout. Or maybe the medúlla is always globulosa and only the amount of intermixed hyphae varies. (So sometimes it looks more like one of them, in other collection more like the other structure.) Or maybe I'm confusing 2 species together...?
The two-layered excipulum in P. michelii is also described in an article by C. Frund (2009): Une pezize commune des forêts de feuillus. Peziza michelii (Boud.) Dennis. Mycol. Montenegrina 12: 65-68.

thx for your reply.
I indeed forgot to mention the mesurements of the spores: 15.82x9.25 (H2O) / 15.41x9.38 (Cotton bleu)
You can be wright for michelii. I think I interpreted the spore ornament wrongly. I thought the ornamentation here was very fine instead of distinct.
I include here some better pictures of the spores.
It seems the form of excipulum is not a certain element in determination of Pezizas.
