Pyreno with fusiform spores

Juuso Äikäs, 25-03-2024 19:14

I found some small black pyrenos growing on a dead, attached branch of Salix caprea next to Orbilia vinosa. The perithecia are semi-immersed and papillate.

The spores are fusiform and have a few large guttules. The mature ones have five thin septa and measure 19.6 - 24.8 × 6.2 - 7.1 µm. Asci 8-spored, IKI negative.

Some help with the ID would be nice.

Re : Pyreno with fusiform spores

I think I might have a lead now: maybe Chaetosphaeria or Zignoëlla?
