Bonjour à tous, Marcel LECOMTE président de L'A
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,
Peter.
When you put KOH to the hairs and excipulum, it turns dirty violet.

Thank you very much, the hairs and excipulum in 10% KOH turns dirty violet :-)
