Pyreno on Fagus

Andreas Millinger, 19-11-2025 20:51

Good evening,

found this species on a felled trunk of Fagus sylvatica in mixed Fagus-Picea-Abies forest at about 800 m. Reminds me of Hypoxylon or Biscogniauxia but spores are like Nectria, uniseptat, warty, measures 16.7-18.7 x 8.4-9.7 Q=2.0, constricted at the septum. Asci do not show any staining at the porus, neither with Lugol nor with CR.

Hope, somebody can help me ...

Thanks a lot in advance!
