Hi Thomas, 
I am currently preparing a thesis on the Mytilinidiaceae family and would be interested in your collection if it is in good condition and has a sufficient number of asci. If you are unable to have it sequenced, I will do so. I already have an old Finnish collection from Marja. I would be interested in having a more recent one. I think it could be an Actidium species.
Best wishes,
Alain
