Calicium cf. viride
Alex Akulov, 29-07-2012 22:07
Alex AkulovDear Friends
Some days ago in the Ukrainian Carpathians I found nice lichenised Ascomycota representative - Calicium. I think it is Calicium viride or something close.

Unfortunately, I have not literature devoted this group of fungi. Can you help me with it? Did you meet this species in your countries?

Grateful before,
Alex

Hi Alex

you did not see any Asci and Ascospores? I fear without it will be quite imposible to determine.

Dear Zotto,
I know very little about Calicium and would like to read some species characteristics to know what I need to look for and how to work with this genus.

Hi Alex

I will send you three papers from which I have pdf. Possibly there are better ones but these I found in my pdf collection.

Re : Calicium cf. viride
Hi Alex.
with rounded, brownish spores, it must be a Chaenotheca species. In this genus is important to determine the algal thallus genus (Trentepohlia orange alga or green one and in this case the shape of the alga).
Best wishes. Javier Etayo
