Hi all, I found today this ascomycete growing on cupule of acorn.
Cup 0,5 mm across, flattened, attached by sort stalk.
Spores 10-11-5,5-6 mm, ellipsoid.
In my opinion, the fungus was not young.
I'd like help in identification.
Thank you in advance.

Re : Ciboria batschiana in spring?
C. batschiana grows on the cotyledons of oak, not the cupule. As you have the fungus fresh you should make a preparation in water without too much pressure to show the vital characters.

Re : Ciboria batschiana in spring?
Dear Zotto,
Thank you very much for your attention and the recommended method. Unfortunatelly there are no more fresh fungus.
The reason I applied too much pressure, more useful information I can not show it.
Maybe next time.

Re : Ciboria batschiana in spring?
I remember C. batschiana has 2-nucleate spores and that would be visible in living spores in water - a possibility you still have by rehydrating.
Just read the apo diameter: 0,5 mm, is this right?

Dear Zotto,
Oh, no, 0,5-0,8 cm
I do not understand why I can't see the wall Asci.

Re : Ciboria batschiana in spring?
Another idea: You have deBary-bubbles in the spores (DBBs, a gaseous phase). This is caused by your mounting medium (lactophenol?). I am unaware of DBBs in Helotiales, maybe your fungus is a Pezizales? Perhaps overmature?

Re : Ciboria batschiana in spring?
I wondered at the sight of bubbles, thank you for drawing my attention to it.
Lugol was mounting medium.
I'm glade the other idea, overmature Pezizales.
Thank you very much

Re : Ciboria batschiana in spring?
When you have mounted a fresh sample and it formed DBBs, it cannot be in Lugol. It must contain a viscous ingredient that extracts water, and I suppose you used Melzer.
