Winter Cistella on Prunus padus
Marja Pennanen, 20-03-2020 18:01
Hello forum,

I seldom find hyaloscyphaceae on Prunus padus.

Now I found some creamy ones, that seem to turn orange when older.

They are up to 0.7 mm wide.

The spores are about 6-9x1,5-2.

The asci are about 30-40x5-7. faintly IKI blue and paraphyses are slightly lanceolate, about 2 wide, maybe a bit longer than asci.

The hairs are 10-30x2-3 and when the tip is swollen even 6 wide.

The cells turn orange in older fruitbodies.

Raitviirs key gave me no releaf to my determination trials, so once again I trust to your better knowledge: Marja

Hello Marja!

this is really difficult. Did you compare Cistella dentata?

Re : Winter Cistella on Prunus padus
Dear Zotto,

not that! If I believe in you and I do, no. The microscophy of dried material, that Raitviir in my knowledge used is smaller than the microscophy of fresh and  these seems to go on inspite of any virus activities.

PS: the microscophy did not change after 2 days in fridge.
