Valsa? on Ribes
Marja Pennanen, 25-02-2015 20:26
Hi again,

on the same twig of Ribes nigrum with propably Didymella grew some Valsalike pyrenos.
There were groups of black penetrating papillas on the surface, group width about 0,5 mm.
The spores were hyaline, allantoid about 7-9x2.
Asci were thin walled about 20-28x5.
Valsa frangulae is close, but that has not been found in the neighbourhood and that makes me very unsure of my determination.

Other opinions? Marja
