Hyaloscypha/Psilocistella on hardwood

Hi again


I'd like to call it Hyaloscypha quercina Velen.[= Psilocistella quercina (Velen.) Svrcek] but I think it is not possible because the anguste cylindricae spores 5-8 in the original description of this taxon. Hyaloscypha quercicola (Velen.) Huhtinen with asci not arising from croziers, shorter hairs and ascospores 7-12.5 x 2-3 microns, neither fits well with my fungus, but yes, it looks alike Baral's folder Psilocistella quercina.


The scattered apothecia of my collection are somewhat sessile, up to 0.6 mm, whitish but reddening after damage or with the age, but not with NH4OH. Asci IKI b Calycina-type, 8-spored, arising from croziers. Excipulum of textura prismatica. The long hyaline obtuse hairs, up to 125 x 4, are undulate, up to 4-septate, arising from slightly broadened base. They don't have any apical solidification (as in Protounguicularia variepilosa). No subiculum I have seen.


Could you help me again?


Thanks a lot

Re : Hyaloscypha/Psilocistella on hardwood
I think it is quercina = variepilosa. The hairs look a bit thick-walled, but I cannot find another solution.

Re : Hyaloscypha/Psilocistella on hardwood
I forgot to add that hair length seems unusual, I think it would be exceptional so far in this species.
