I am new to this site, so please forgive any mistakes.
I think this fungus is Peziza cerea.
Is that correct?
Best wishes,
Martin

Hi Martin,
bienvenue sur le forum Ascofrance !
If you follow Hansen & al. 2002 , P. cerea is synonymous to P. varia.
I wonder whether the measured spores are mature as they are still in the ascus , which may explain they are shorter as they should be for P. varia

The Piximetre data is as follows (Classical formula, 80% of measurements):
(13.8) 14.7 - 15.9 (17) x (7.8) 9.2 - 10.6 (10.9) µm
Q = (1.4) 1.43 - 1.7 (1.9) ; N = 50
Me = 15.3 x 10 µm ; Qe = 1.5
From that can we say it is definitely Peziza varia (= cerea)?
Best wishes,
Martin

Martin, these measurements actually match P. varia's, to my knowledge.
In many collections, fortoulism in paraphyses can be observed in P. varia, but this character (which I cannot observe on your pics ) is not compulsery
