Re : unknown ascomycetes from Greece
This is a Lamprospora species, but it would be better to observe the ascospores in Cotton Blue.
After your pictures, it could be L. maireana.

Re : unknown ascomycetes from Greece
Lamprospora.
Après, sans coloration des spores au bleu coton, c'est impossible...
On dirait cependant que l'ornementation est formée de gosses verrues hémisphériques farcies de fines gouttelettes ce qui pourrait indiquer Lamprospora maireana, espèce peu commune mais il faut colorer les spores pour être affirmatif.

Re : unknown ascomycetes from Greece
Hi!
It's L. maireana, it can grow either with Archidium alternifolium or Fossombronia spec. (shown on your first pic). In Portugal it is common on both.
Reference:
Benkert, Didier (2002): Beitrage zur Kenntnis bryophiler Pezizales 10. Variabilitat und Verbreitung von Lamprospora maireana Seaver und L. tuberculatella Seaver. Feddes Repertorium 113: 80-95.
Best wishes,
