Calycina on Sorbus?

Juuso Äikäs, 14-11-2020 08:27

These were growing on a fallen trunk of Sorbus sp. together with Calycina citrina and possible Lasiosphaeria sp. The ascus pores turned almost black in Lugol's solution, but with some overexposure they seem to be hemiamyloid.

Spore measurements:

7 - 8.09 (8.1) × 2.6 - 2.9 µm
Q = (2.4) 2.42 - 3.05 (3.1) ; N = 4
Me = 7.4 × 2.7 µm ; Qe = 2.7

Re : Calycina on Sorbus?

This is Calycina languida, the form without croziers (as in the type).
