White Ombrophila on Picea cone
Juuso Äikäs, 15-09-2022 08:09
I found some small (ca. 2 mm wide) white Ombrophilas on a couple blackened Picea abies cones that had fallen into a paludified groove.

Asci with croziers, measuring 70 - 80 × 8 - 9 µm, IKI+. Paraphyses cylindrical, with a long VB at the top part. Medulla apparently gelatinized, with small crystals. 

The spores measure 8.9 - 9.3 × 4.4 - 5.1 µm.

O. tetracladia is the best candidate I found. What do you think -- could it fit, or is this something else?

...

Or maybe just O. violacea?

Re : White Ombrophila on Picea cone
Bonjour Juuso, 

I often find on this substrate and in such sites O. tetracladia.
It seems to match your find. 
What does prevent you from this ID ?
Amitiés Michel

Re : White Ombrophila on Picea cone
Thanks for the reply! I'm just not at all familiar with that species, and am not sure if it occurs here (not included on the Finnish list). On GBIF there are just three occurences, and the northernmost is from Southern Germany (quite a bit south of here).

Re : White Ombrophila on Picea cone
I also would identify it like this. Regrettably wse rarely see the anamorph in nature along with the apothecia.
Juuso Äikäs, 15-09-2022 16:49
Re : White Ombrophila on Picea cone
Alright, thanks! According to the info I found, the anamorph goes by the name Articulospora tetracladia, and is an aqueous hyphomycete (presumably the tetracladia part of the name comes from it's shape).

yes, that's it.
