Rosellinia species?
Ralph Vandiest, 17-11-2013 22:19
Ralph VandiestHello,
I found these species on dead wood (I think fagus). Size is 0,5mm, spores are mitre-shaped and measure +- 50x5µm. With the key I have, I don't find any species in the genus Rosellinia. The closest to my spore size is R Necatrix. Ps substance at the inside of the fruiting body is green.


regards,

Ralph

Re : Rosellinia species?
Hi Ralph,
It's not a Rosellinia species but Lasiosphaeria ovina.
Ascospores of Xylariaceae are different.
