Hyalorbilia or Hyaloscypha ?

Re : Hyalorbilia or Hyaloscypha ?
Surely a Hyaloscyphaceae in the older sense. I cannot clearly see the paraphyses and their contents. Important would be the margin and exterior, the glassy structures you show are probably not part of the fungus.

Re : Hyalorbilia or Hyaloscypha ?
Hi Vasileios, 
As seen on your macros, the margin of the apos is hairy .
Not an Orbiliale to me.
Do the glassy process elements on your 4th pic represent these hairs ? If so, do their content disappear in KOH ?
