A colleague from Norway brought one ascocarp of this Ascomycota.
I have no experience with them because I have never microscopic this species.
Contrary to appearances, ascocarp is very poorly mature. His appearance is probably the result of adverse weather conditions. I made about ten samples and found only a few spores that looked almost mature. Therefore, it must be assumed that the length of mature spores is slightly larger.
Of course, I microscopic the dry material, so sorry for the poor quality of the photos.
Could this be Urnula hiemalis?
