Psilachnum or some Hyaloscyphaceae on hygric Sorbus wood

Hello guys,I recently collected some strange possibly Psilachnum species on decomposing fallen hygric branch of Sorbus aucuparia in (sub-)alpine region (High Tatras - Slovakia, 1350 m asl).
According to Raitviir's key, I assume, that it could be some Psilachnum species (on woody substrate). Please can someone help me with the precise identification ? Maybe Zotto will know ...

Spores - narrowly ellipsoid to elongated ellipsoid, often with 2 bigger oil drops and many smaller ones, 9,1-10,8 x 3-3,8 µm
Asci - 8 spored, croziers present (Haken +), IKI+ bb
Paraphyses - filiform, with numerous oil content (oil drops)
Hairs - lanceolate, +- blunt, smooth

Re : Psilachnum or some Hyaloscyphaceae on hygric Sorbus wood
Hi Filip
the hairs clearly refer this species to Hyaloscypha. I only wonder about the paraphysis content which is quite impossible here. Surely this is no oil, you can easily check this by adding 1-5% KOH (LBs resist in KOH).
If you have CRB (aqueous Crresyl Blue or Toluidine Blue) you can try to stain them, which needs some patience. Hyaloscypha vitreola has paraphyses with single guttules but these are SCBs which do not stain in CRB, whereas VBs which I presume here do stain turquoise.
