Godronia like on Rose
Marja Pennanen, 04-07-2014 16:03
Hi,

these look like Godronia, but the microscophy is odd.
They are under 1 mm wide.
The spores have 1 septum, which develops allready in ascus and are about 10-16x2-3  and germinate fast.
The asci are about 80-100x4-5 and paraphyses are very narrow and filiform.

Is there a Godronia species with this small spores?
If not, what can this be?

Re : Godronia like on Rose
Hi,

it must be Godronia rosae, which I found here in Database section.
Should have guessed...

HI Marja

my measurements are bigger, but I did not compare Groves.
