Lachnum clavigerum?
Juuso Äikäs, 05-07-2020 17:52
I found these growing on dead, fallen canes of Rubus idaeus a couple days ago. 

MLZ+, croziers-, crystals+. 

Spores:
(8.8) 9.6 - 11.5 (13.2) × (2.3) 2.4 - 2.6 (2.7) µm
Q = (3.5) 3.7 - 4.6 (5.6) ; N = 20
Me = 10.6 × 2.5 µm ; Qe = 4.2

Based on the substrate and microscopy, L. clavigerum is the best candidate I found. The spores are maybe a bit large but would at least almost fit the range, I believe.
