Ciboria-like apothecium on deciduous stick

I have difficulties finding even a genus; it has much in common with Ciboria but I don't think the spores fit in.
I would appreciate opinions on this one.

Re : Ciboria-like apothecium on decoduous stick
Yes, clearly sclerotiniaceous. Although very well documented, I have no clear idea. Spore guttulation together with globulosa could point to Rutstroemia bolaris, but that is only known from Carpinus and its spores are much larger and the VBs in the paraphyses brownish and elongated. Perhaps you can clarify the substrate? Alnus and Betula have very characteristic perforations of the vessels (in radial section).

Re : Ciboria-like apothecium on deciduous stick
Thank you! I think Salix can be excluded.

Yes! And Betula vs. Alnus is difficult. Perhaps it works with a cross section but I was repeatedly in doubt.
