Black on Picea abies
Marja Pennanen, 06-08-2011 12:09
Hello,

these black spots are up to something like 0,5x0,1 mm.
The asci are 50-65x3-4.
Spores are 12-16x2 and seems to develop one septum.
Maybe this represents a Mytilinidiaceae species. Could this be for instance Actidium hysterioides or A. nitidum?

Yes very probably A. nitidum.

Re : Black on Picea abies
Thank you!

Once again a representative of a new genus for me.
The species may even be new to Finland.

Hi Marja,
10 years later, I read again your post, and my answer. No I can say that is not Actidium nitidum, but un ined. species. Did you keep material ? 
I find a similar species several time, but on  Abies. Did you sure of Picea ?Best wishes,
Alain

Re : Black on Picea abies
Dear Alain,

I have the specimen and I just checked it. It seems to be a small branch of Picea abies, where those black ones grow.

Greetings: Marja
