Rosellinia mycophila?
Mirek Gryc, 19-03-2021 14:49
Hello everyone.
I am studying this species for the first time, so please for your opinion, the more that the collection is very mature and I can not check all the features. When identifying I can only take into account the spores and morphological characteristics.
Spores:
(16.6) 17.9 - 20.3 (21.5) × (5.4) 5.41 - 5.9 (6.5) ?m

The remaining features can be seen in the pictures.

They grew on Picea abies.

greetings
Mirek

Re : Rosellinia mycophila?
Perfect.

Sometimes R. mycophila and R. thelena are mlixed together.Checking it could be a good thing.

Re : Rosellinia mycophila?
Hi Alain.
I read about it, so I made about 15 samples, from different places. I did not notice spores with appendage typical for R. thelena.
It seems that R. thelena will still have to look.
Thank you Alain.
