I rarely meet purple Peziza so I don't have much experience with them, so please help me identify this collection.
Very microscopically similar to P. celtica but not in all details.
It grew on a gravel bed, on the side of a forest road, where rainwater collects, so the ground is wet. Ascobolus behnitziensis grew nearby.
The body is very thin, delicate.
I thought I had harvested the ascomat not ripe so I kept it for a few days, but without much effect. The spores grew minimally and the ornamentation remained the same, so their surface is only slightly rough. Certainly not like P. celtica.
Their dimensions are also much smaller.
I also don't like the ectal excipulum texture. Cells are oval in my collection.
Spores;
(13.4) 13.5 - 16.1 (16.6) × (7.4) 7.5 - 9.9 (10) µm
Q = (1.5) 1.6 - 1.9 (2); N = 14
Me = 14.8 × 8.5 µm; Qe = 1.7

Re : Peziza with a purple hymenium?
What would you say about Peziza exogelatinosa?

Re : Peziza with a purple hymenium?
I guess the spores are too small for this species? - then maybe P. pauli (= martinii)?
What do you think about it?

Hello Mirek,
yes, it seems to have a gelatinous layer on surface. But which species it is... I've seen two light violet collections with gel layer and neither was exactly fitting P. exogelatinosa:
http://ascofrance.fr/search_forum/54179 (H+, more rough ornam., paraphyses hyaline)
http://ascofrance.fr/search_forum/54096 (H-, paraphyses with brown droplets)

Thank you Victoria!
I have seen these collections of yours before but as I mentioned at the beginning, my experience in this case is too little to make a genre decision.
I still have live fruiting bodies and I will grow them to check the dimensions of the spores, although I suspect that it will not help me much ... no literature on these species.
greetings
