Who: zaca

Very similar to Acrocordia conoidea, which lives on rock, while this specimen grows on the bark of a chestnut. This is my first observation of this species.

The microscopy seems to confirm the initial guess. Here are the dimensions of the spores:
21.3 [24.9 ; 26.4] 29.9 × 8.7 [10.1 ; 10.7] 12.1 um;
Q = 2 [2.4 ; 2.6] 2.9 ; N = 31 ; C = 95%;
Me = 25.6 × 10.4 um ; Qe = 2.5.
