Orbilia on Betula bark
Enrique Rubio, 09-05-2025 19:10
Enrique RubioHi to everybody.
This Orbilia (apos up to 0.5 mm), grew on bark of a Betula branch lying on the ground at 1800 m of altitude. Glassy processes are present. Asci 8-spored. Paraphyses ellipsoid-spathulate to lanceolate or mammiform. Spores without subbasal constriction.
I think it could belong to the series Abutilones. Perhaps it could be Orbilia rehmii or some similar species.
What do you think?

In fact it is a relatively common species at the mountain level in my country, on Salix branches still attached to the tree. I should have remembered it.
