Hello everyone,
I am new here in the forum. Thank you for the welcome.

Enclosed is an enquiry from a hobby mycologist friend. It is about a "Peziza", we think "varia-cerea complex". What do you think about the sort?
"Found on 07.05.21 on previous year's burn site in a garden.
Find description:
Macroscopic:
Frkp. on burn site i.e. on soil on burnt wood and also directly on burnt wood stump.
Fkrp. 1-3(4)cm, cup- to bowl-like, later more flatly spread.
Rim: +/- wavy curved (older inwards and also outwards), partly weakly torn, but rather not granulated.
Hym: Yellow-brown, older more brownish, smooth to partly slightly wrinkled in the middle.
Outer surface paler yellow-brown, scabby to grey-whiteish.
No actual stalk, but constricted in the middle like a wrinkled stalk.
Frkp: solitary, in groups and also several grown together.
Microscopic:
Sp: 14-16.5 x 9-10.5 µm / smooth to very finely warty (1000s + BW blue) without oil droplets.
Asco approx. 240-280 µm x 11-13. tip in barl.sol. IKI + paraphyses slender, tip weakly thickened to ca. 4-6µm.
Textura: middle textura inticrata narrow, barely visible to naked eye > stereoloupe + micrographs."

Attached are some pictures.
We are looking forward to your answers. Many thanks.
