Bernard CLESSESur brindille enterrée.

a) paraphyses cylindriques, très guttulées
b) asques IKI+, à crochet à la base (jeunes asques)
c) spores ovales-subfusiformes, à microguttules vers les pôles : 11-12x4,5-5

Une idée ?

Phaeohelotium imberbe seems to fit.

Good evening Zotto,

Thank you very much for your answer!


I know it's a matter of neophyte but can you remember the difference between genus Phaeohelotium and genus Hymenoscyphus ?

Best regards,

Bernard

Phaeohelotium has mostly rather short apothecial stalks and non-scutuloid ascospores, often also short-celled isodiametrical excipular cells at the flanks..
