I have collected this last year.
These grow on Picea abies debris, mostly on needles and are about 0,7-1mm wide.
The spores are about 16-22x5-8 and seems to have some kind of hyaline appendages.
I saw no asci, suppose, that these are quite mature.
The determination trials ended to Anthostomelle genus.
Can this be a species in that genus and if so what?
I have found no Anthostomellas ealier...

Re : Anthostomella?
How about Rosellinia thelena - should have rather long and very pointy appendages. It likes Picea litter.

Re : Anthostomella?
Hi Thomas,
you must be right.
I'm very poor with these black ones. The species seems to be LC in Finland.
New species and genus for me anyway :D

Re : Anthostomella?
Hi Marja and Thomas, nordic friends,
It would be a good thing to see asci and ascospores in good conditions. Perhaps R. mycophila is not excluded ? (what do you think Thomas ?) But t seems to have the appendages of R. thelena.
Please Marja, show us appendages.

Re : Anthostomella?
Yes, based on the illustration I cannot exclude mycophila but, at least here in Denmark, I mostly get it with Abies. Spores in good condition and asci likewise makes life easier :-)
