Hi,

I think this collection is close to Lasiosphaeria stuppea but still differs a bit in some aspects. First of all the description:

On a standing, dead, decorticated, little tree (Abies), approx. 150 cm above the ground. Ascomata black, rough, at first immersed in the substrate, when mature still often a bit immersed, usually covered with light brown setae but some ascomata also without; asci 8-spored, without subapical globulus, with well visible, simple apical ring; spores quite a long time hyaline, then turning brown, non-septate, smooth, bent in the middle, without appendages, 35-50 x 8-13 µm; peridium two-layered, with a thick, dark brown outer layer and a thinner, hyaline inner layer.

I hesitate to call my collection Lasiosphaeria stuppea because the spores seem too long and they are smooth, non-septate and the apical ring is simple and not double. The other characters fit well with the description by Candoussau, Fournier, & Magni. I am really interested in your opinion about this find!

Best wishes,

Gernot
