Yellow with Perichaena
Marja Pennanen, 04-08-2011 15:12
Hello forum,

when studying Perichaena I noticed some 0,1-0,2 mm wide stuff growing among them.
I checked them and they appeared to be ascos.
The spores are multiguttulate, about 30-50x3-4.
Asci are about 70-80x7-10.

I got absolutely no clue of what this could be: Marja

Re : Yellow with Perichaena
Thank you Alain!

What I found from internet seems to fit.
As you may guess, this is totally new genera for me :D
