Psilocistella?
Marja Pennanen, 20-06-2013 16:47
Hello again,

today I found something new for me on propably Helianthus tuberosus stems.
They are about 0,2-0,3 mm wide.
The spores are about 6-8 (-10) x1,5 and asci 30-40x5-6, IKI-.
Paraphyses are narrow and don't exceed asci.
The hairs are 2-3 septate, about 30-60x3-4.

Could this be a Psilocistella species?

Re : Psilocistella?
Look closer to the hairs: are they warted? Or do they have partly a glassy cap?

Re : Psilocistella?
Dear Zotto,

in my eyes these are not warted and KOH caused no reaction.

I thought I see a glassy cap on the left hair of the right photo. But this is not sure to be seen.

Re : Psilocistella?
Here is another poor photo of the hairs.

So no glass but it looks rough to me. I suspect a Cistella.
