Rosellinia key
Eduard Osieck, 14-10-2015 22:18
Can somebody provide the key from the world monograph (2013)?  Or is the key available at http://pyrenomycetes.free.fr/rosellinia/index.htm still useful in North and Central Europe?

I have a collection provisionally identified as R. mammaeformis but the spores are rather short (15-17 um) and more important the slimy sheath appears to be lacking (as observed in indian ink) and the ascomata are partly immersed (about half).

Thanks for the help, Eduard

Hi Eduard,
this is likely Nemania confluens.

Hi Jacques,

Thank you very much for the tentative identification. I should have known better!

Best regards, Eduard
