Bonjour , 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

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.
