White Hymenoscyphus on bark

Here is a Hymenoscyphus species growing on bark (probably Fagus) in a wet place.
Apothecia Ø 1-1.8 mm, sessile or short-stalked, pure wihite.
Ectal excipulum of t. prismatica.
Asci without crozier, pars sporifera 26-32 µm, IKI+ (bb)
Paraphyses without VB
Ascospores 11-14 (18) × 3-4 µm, sometimes with a septum (only when ejected), OCI 1-2.
H. phyllogenus seems close, but the substrate is different.

Re : White Hymenoscyphus on bark
Hi Nico
this reminds me strongly of my Hymenosc./Phaeohelotium "Cagne" on coniferous wood. See my folder "monticola".
The VBs in the paraphyses are multiguttulate and vary between faintly and medim refractive.
So far 3x on coniferous wood in Vosges.
Did you look for the wood anatomy? In cross section coniferous wood is easily determined, and Fagus also.

Re : White Hymenoscyphus on bark
Not easy to study the anatomy of rotten bark... As there were some Picea abies in the same place, this is an option.
I agree that this H. "Cagne" could fit, although the VB in the paraphyses are not so distinct in my collection.

Re : White Hymenoscyphus on bark
Ah yes, you wrote bark. Bark is not easy to identify. Is there no adherent wood? Fagus bark has a very characteristic inner side.
