Asco on decorticated wood of Fagus sylvatica

Hi to all:
I'd like to know your opinion about this gregarious apothecia that grow on decorticated wood of Fagus at 1000 m of altitude. They are sessile, not cupuliform, up to 200 microns, withish ochraceous at maturity.
Asci IKI negative, without croziers. Maybe a Pezizella species?
Many thanks again for your help
Enrique
