Hi everybody,
I have found this species on a fireplace, growing on ash.

Apothecium: 0,8 - 1,0mm
Lateral Hairs: light brown, 2-3 septate, 70-80 x 4,0-4,8 µm
Marginal Hairs: Hyaline, Single segment, based on an subglobose cell, 35,5-39,5 x 6,3-7,9 µm
Spores: Thick walled, smooth, 15,8-16,6 x 11,9-12,7 µm
Paraphyses: light brown, 4-7 µm at the tips

I have no idea, may be somebody can help

Thanks
