Bonjour, Quelqu'un peut il me donner un conseil pour identifier ces ''apothécies'' sur thalles du lichen Evernia prunastri ?Â
S'agit il d'un lichen parasite ou d'un ascomycète lichénicole ?Â
MerciÂ
Amitiés. Michel

Re : Parasite de Evernia prunastri
I guess this lichen-parasite is in to find in the neighborhood of Abrothallus De Not.Do i count 6 spores in the asci ?
Best,
Marco

Re : Parasite de Evernia prunastri
I think this is probably an Arthonia, not Abrothallus - the asci and spores are quite different. I'm not aware of one that is a parasite of Evernia, it could be undescribed (if you believe that they are host-specific...)
Best wishes
