Peziza - please help.
Sergey Markov, 02-06-2022 12:52
I'm having trouble identifying a specimens of Peziza.

Apothecia are not small, up to 80mm in diameter. On loam soil  in wet place under Corylis. In the field i assumed the species from P.varia/P.repanda complex, but microscopy brought a surprise - ornamented (finely punctate with some interconnects) spores. Now I don't understand at all what kind of species it is and I ask for help identifying it.

Microphotos of excipulum are in the order from outer to hymenium.

Re : Peziza - please help.
Thank You very much, Michel!

I studied "Lantieri, Angela & Medardi, Gianfranco & Alvarado, Pablo. (2016). Morphological and phylogenetic clarification of Peziza arvernensis, P. pseudovesiculosa, P. pseudosylvestris , and P. domiciliana." and my specimens fits very well into description of P.arvernensis.

Before that, I was mistakenly sure that this species grows on burnt substrates, plaster, brickwork, e.t.c., but not on soil and/or woody remnants

Re : Peziza - please help.
Another interesting character of this species is the presence of bipolar spore granules (see your pics 7 to 9). Species of the varia complex do not show such granules.
