My first impression was sth like Rutstromeia, but they have larger spores and are IKI+

Spores (size): 6.8 - 9.4 x 2.6 - 4.4 µm - Q: 1.55 - 3.34 (Ø LxB: 8.2 x 3.3 ØQ:2.6 N: 8)
Spores irregularly ellipsoid
Ascus: IKI-, biserriat
Growth on wooden detrius and wood

size max. 10mm

This would require living paraphyses. Were they multiguttulate (refractive VBs)? It could be Hymenoscyphus pani, which has inamyloid asci and inconspicuous contents of the paraphyses.

H. pani and H. peruni are related to H. repandus (in my menthae clade).
