On Potentilla
Marja Pennanen, 08-08-2010 15:34
Hello,
once again I'm lost in the jungle of new species.
Along with that new to me Graddonia I found something tiny on Potentilla palustris leaves.
This seems not to be Mollisina alni, because this is IKI+.
These are something like 0,1+ mm wide:

Re:On Potentilla
The spores are 5-9x1,5-2 and asci 30-47x5-6, IKI+.
I can't say, that I saw paraphyses.
This photo hopefully tells the rest of the story:

Abosutely no idea of where to start to look for the species: Marja

Hello,

It can look like this too, these are about 0,3 mm wide and grow on the leafribs::

Re:On Potentilla
The first ones were propably very young and had no paraphyses yet.
I suppose that they have paraphyses, too.
The marginal cells are hyaline (once again sorry for the poor quality):
