Pezizellaceae on Salix leaves
Michel Hairaud, 08-12-2017 15:22
Michel HairaudBonjour ,

Merci pour l'aide apportée à la détermination de cette récolte automnale sur feuilles de Salix sp.
Apothécies de diamètre -> 0,4 mm, blanches, stipitées à base noirâtre, sur les nervures de la feuille.
Asques H+, IKI+ de type Calycina, 60-65 x 6-7,5
Spores scutuloîdes, 14-19 x 2,5-2,8
Ectal T. prismatica

L'espèce la plus proche me semble Calycellina leucella .

Amitiés
Michel

Hi Michel!
I think it is C. leucella.

Re : Pezizellaceae on Salix leaves
Thanks Zotto, I was wondering because I thought it did not match quite completely the species regularly found on Alnus fruits and i did not see it yet reported on Salix .

Re : Pezizellaceae on Salix leaves
It occurs well on leaves also. And the slight median constriction of the spores is also perceptible on your upper spore, though vaguely.

Did you collect it now? Because I want to add the date to your photos, and best also  a name of the site.

Re : Pezizellaceae on Salix leaves
Yes the median constriction was also a questionable point.  It is often more obvious in other collections, though emphazized at overmature stage.

This collection  Riom es Montagne , France, Cantal (15) 9 10 2017 on Salix sp. leaves among a peat-bog sphagnum .  Macro and micro pics and exsic under file ref MH 31017.

Merci encore, camarade. Michel
