Hymenoscyphus "schwegleri" : confirmation
Nicolas VAN VOOREN, 18-09-2011 19:41
Nicolas VAN VOORENRécolté 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.

I think your macro as well as micro fits this species.

What is A. alnobetulae???

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.
