Peziza cerea-varia?
Dirk Gerstner, 25-05-2021 08:40
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.

Dirk

Re : Peziza cerea-varia?
Hi Dirk , 

Welcome on Ascofrance, 
Many characters you present for this collection match P. varia , especially the spore size and spore very fine ornementation 
You actually show many features of your collection. One more important character is missing : the paraphyses contents but in that case, spore characters actually act as species signature. 
As you may have seen on the late papers by Nicolas Vanvooren in Ascomycete.org, this species belongs to the genus Peziza sensu stricto.
Amitiés
Michel

Re : Peziza cerea-varia?
Hello Michel,

Thanks again for the welcome in Ascofrance and the quick reply and help.


I didn't have the Peziza in my hands, I got the macro and micro photos from my friend, who also found the Peziza.
We will have to pay more attention to this in our future identification attempts.
I don't have any more photos of the paraphyses.
But I am attaching pictures and hope to shed some light on the matter.


I don't know the work of Nicolas Vanvooren directly, but I will try to get it.


Kind regards
Dirk

Re : Peziza cerea-varia?
Hello Michel,

I have received new photographs of the paraphyses from my friend today and am attaching them above for completeness.


Merci beaucoup et salu
Dirk
