Atendiendo al sustrato, quizás Hymenoscyphus calyculus.
Saludos.

Re : Phaeohelotium on Fagus wood
Hi Patrick
this is typical P. epiphyllum (= Hymenosc. epiphyllus).
Important are the multiguttulate paraphyses for delimitation against P. monticola. They are the only living cells on your photos. It is not good to make the general preparation in Lugol, only at the end you can add it for the amyloidity. The spore oil content is importnat too, and it is a bit distorted on your photos.

H. epipyhhlus may occur with inamyloid asci, but usually ithas an amyloid ring - genetically both are identical
