I found this one on decidious wood ( Fraxinus or Padus ).The apothecia are mostly 0,5-1 mm wide and high (max. 2 mm). Hairs cylindrical septate with incrustation 60-80 x 3 µm. Paraphyses cylindrical diam. 0,5-1 µm. The asci are 8 spores 45-55 x 4-5 µm , not iodid reaction or weak on porus. Ascospores 6-10 x 1,5-2 µm often with two small oil drop at poles. Textura prismatica/angularis
Thanks and Happy New Year

This looks like Proliferodiscus pulveraceus to me. Yellow hymenium and coarsely encrusted hairs.
The spores are a little narrower than normal, but otherwise it agrees with the literature:
Microfungi on Land Plants (M. B. Ellis & J. P. Ellis) Page 7, Figure 17
Ascomycetes in Colour (P. I. Thompson) P124, Species 248
With Best Wishes,

When you put KOH to the hairs and excipulum, it turns dirty violet.
