White discs on Potentilla
Marja Pennanen, 04-08-2013 11:36
Hello forum,

remnants of Potentilla palustris leaves carried some interesting whitish discos.
I forgot to measure, but these were tiny, maybe 0,1-0,3 mm wide.
Spores are about 12-16x2,5-3 with few droplets.
Asci are about 45-60x7-8, IKI blue.
Cylindic paraphyses may contain Vb:s and are about 2-3 wide.
The marginal cells (may be called as hairs ;) ) are something like 20x2 and may contain Vb:s, too.

Some Calycellina species?

Re : White discs on Potentilla
Dear Zotto,

that was fast. Thank you!
Seems to be originally a Karsten species.
