Récolté cet Hymenoscyphus en Savoie, alt. 1700 m, sur branche morte d'Alnus alnobetulae.Spores allongées, parfois courbées, guttulées (OCI = 2+), 17-22 x 4-5 µm. Asques avec crochet, IKI + (bb). Paraphyses contenant de nombreuses vacuoles. Excipulum ectal de textura angularis, mêlé de cellules plus allongées.
Photo & PDF joint.
J'arrive à Hymenoscyphus "schwegleri" avec la clé de Zotto, qui serait illustré (photo seulement) dans B&K vol. 1 sous Rutstroemia bolaris.
Hormis Zotto, quelqu'un a-t-il déjà collecté cette espèce ?

Hi Nicolas
I am actually not sure whether this "schwegleri" is something real. Presently i would say it is merely H. epiphyllus.
Look here, this I think is epiphyllus (on Alnus viridis). The photo in Breitenbach pl. 149 shows this species, in my opinion, though the micros belong to Rutstroemia bolaris.

OK.
A. alnobetulae is the correct name for A. viridis.

Re : Hymenoscyphus "schwegleri" : confirmation
In Wikipedia it is still a synonym of of the valid viridis, even in the French.
Do you have a website or paper about that change?

Re : Hymenoscyphus "schwegleri" : confirmation
thanks, you are obviously right. I only was unable to find a reference to an article, that explains the reasons for this name change.
