Bonjour,
poussé parmi l'herbe sur le sol.
Spores: 13,34-15,04x7,84-8,55 micron.
Avez-vous une idée?
Merci d'avance

Re : Peziza sp.
OK, this typical ring shape points to the genus Peziza s. str. or to the genera of the /violacea clade. Species with guttulate ascospores are extremely rare in Peziza s. str., so I think your collection might belong to the other clade. Your specimen is very old, so it will be difficult to identify it without more data (colour of pigment, flesh structure, spore ornamentation, etc.).

Re : Peziza sp.
OK, so a true Peziza. The only known species with such guttules is P. domiciliana.
Please check if aspcospores are finely warted (with Cotton blue).
