These little black pyrenos were growing on bark of a fallen Pinus sylvestris branch. Some of the perithecia were more or less round, and some had a little neck.
These appeared to be rather old fruitbodies, but there were spores inside. Some had a septum, which was located either centrally or inequilaterally. The spore surface has some minute ornamentation, and the size of the spores is quite large: 34.5 - 38.5 × 12.9 - 15.6 µm, Q = 2.2 - 2.7; avg = 35.8 × 14.4 µm, Qav = 2.5; n = 5.
Any thoughts about the species/genus/family?

Hi Juuso
Looks very much like Diplodia sapinea, pycnidia with conidia. This fungus is very common on Pinus cones, needles, twigs and bark. May occasionally also be found on other coniferous trees, at least as D. sapinea s.l.
Kind regards
Mathias

Re : Pyreno on Pinus
Thank you Mathias. Yes, that does seem to fit. Apparently this species has just recently begun spreading here.
