Re:Brown on Potentilla
The spores are 11-15x5-6 and carry two or more big droplets.
Asci are 65-80x8-11, IKI+ and paraphyses are 2-3 micrometers wide and a little longer than asci.
Certainly something else and being new to me something, that I can't easily determine...

Still one photo of the microscophy, which somebody might ask for ;)

Re:Brown on Potentilla
Luckily I studied the little pieces, too and found a bigger one, which was fresh. It was nearly 2 mm wide and high. The hymenium was lighter.

Re:Brown on Potentilla
Could this be a Rutstroemia?
I just haven't got the description of R. hercynica, which I've found ealier, but never had it on microscope...
