Hi to all:
These blackish, small (up to 700 microns), gregarious, solitary, globose and semiinmersed pseudothecia were at 2-3 m high on bark of a leaving Fagus sylvatica. They seem to be ostiolate but I'm not sure.
The spores are finally brownish or gloden brown and inconspicually 1-septate. Asci not unitunicate. Pseudoparaphyses are present.
Have you some idea ?
Many thanks again
Enrique

Navicella is placed in Pyrenulales. Now, what about the difference to Pyrenula? A thallus only?
But now I see the spores of Enrique's fungus are much smaller than in Navicella. What is nice to see on your images is the difference of living and dead cells: roundish and with a globose drop when alive, angular and with indistnct contents when dead.

Pyrenula is said to have Trentepohlia algae (with orange LBs in the cells) in their thallus. Can you find any thallus?
