Dark ones on Pimus cone
Marja Pennanen, 26-01-2023 15:23
Hello forum.

I collected some dark ones on Pinus cones last spring in Sodankylä,  Lappland.

Now I finally studied them. They are now, when dry about 0,2-0,5 mm wide.

The spores are about 8-10x 3-4 and develop up to 3 septas.

The asci are about 40x6, IKI-.

I have absolutely no idea of, what these may be.

Hopefully someone here knows more about northern species: Marja

Re : Dark ones on Pimus cone
Hallo Marja!

Should be ostropalean. You can compare Odontotrema (O. minus). I found the spores larger, 11-13 x 5-6, 3-septate, eguttulate. Also Sherwood says 10-14 x 4-4.5 when dead.

But the hymenium should show some IKI-reaction.

Asci have an apical thickening when dead and paraphyses are multiseptate, uninflated, and a little granular around the tips.

Re : Dark ones on Pimus cone
Thank you Zotto!

I just took a fast look at the fungus, so the measurements are few and not very accurate. I do not like dry specimen, they are not easy to handle.  But could not take a microscope with me, when I went to Lapland.

This looks like, what I quickly found from Odontotrema.

Greetings to your family, too: Marja

If not too old it can be that the fungus is still alive. Ostropales are generally drought-tolerant. Rehydrate and it is like fresh.
