Hyaloscypha leuconica var. leuconica?

Spores hyaline (6-0) 7.1-9.0 (-10.4) x 1.9-2.8 microns with two oil drops, from a spore-drop. Those measured within the asci were 7.7-9.9 x 2.8-3.9 microns.
Asci with 8 spores. 42-55 x 6.5-8.0 microns.
Hairs brown with hyaline tips, septate. 70-110 x 3.3-3.9 microns.
It keys reasonably well to Hyaloscypha leuconica var. leuconica, but that species has hyaline hairs.
Any thoughts welcome.
Best wishes, Chris

Re : Hyaloscypha leuconica var. leuconica?
Hello
the brown "hairs" are proably associated conidiophores of a hyphomycete. The hairs of the disco should be hyaline, and their morphology is important to show.
Could it be Protounguicularia barbata?
What is the substrate?

Hello Zotto
This is from September and I no longer have material. It was on burnt wood, possibly Fagus, but not certain.
I will check out your suggestion.
Thank you,
