Didymella? on Ribes
Marja Pennanen,

these black spots were collected today on Ribes nigrum. Here is still winter with snow over half a meter.
They are about 0,5-1 mm wide.
The spores are two celled, hyaline, about 20-28x8-9.
Asci are thick walled, very short stipate, 90-120x15-18.
I ended to Didymella (totally unfamiliar genus for me), but my litterature contains no fitting species. D. proximella almoust fits, but the substrate...
I hope, that someone here has better knowledge and can help: Marja
