Nectriaceae on branch

Juuso Äikäs, 03-05-2022 14:45

I found these growing on a thin, fallen Betula branch. I assume that they are growing from remnants of some old pyreno. The wall of the ascomata had a violet KOH reaction. Any idea what the species/genus might be?

Spores:

(11.1) 12 - 12.7 (13.5) × (5.9) 6.2 - 6.6 (6.8) µm
Q = (1.8) 1.9 - 2 (2.1) ; N = 6
Me = 12.3 × 6.4 µm ; Qe = 1.9
