Per MarstadWe have found this in Norway, growing on Ribes. 1 - 3 mm in diameter, with different shapes.
Conidial sp. 7 x 2,5, hyaline. 
We have found several species on Ribes before but not this one, so we hope to get a name.

The host was found in a forest, so it should be Ribes spicatum ssp. spicatum, but I am not quite sure. Per.

Re : Brown on Ribes.
I found no ascospores. According to the litt. D. ribesia has no anamorph, so that species is not possible.

Re : Brown on Ribes.
Are these erumpent structures the anamorph?

Re : Brown on Ribes.
In my opinion yes, the conidial state of Godronia ribis. The conidial spore are unripe.

Greetings Peter.
