Fruiting singularly and gregariously on a soggy, hardwood stump in Pennsylvania, USA. Apothecia vary from 2-7mm in diameter.
Marginal hairs uni and bifurcated, septate, longest measured ~ 1326, 1171, and 1241 um.
Hairs on back of apothecium short, ~ 300, 270, 230, 333 um.
Spore coarsely ornamentation, does appear to coalesce in some spots.
Spore measure in H20 from ejected ascospores:(14.6) 17.2 - 18.5 (20.1) × (10.9) 11.1 - 11.9 (12.3) µm; Q = (1.3) 1.5 - 1.7 (1.8) ; N = 15; Me = 18 × 11.5 µm ; Qe = 1.6

Re : Scutellinia
Maybe S. pennsylvanica, but the warts on that species seem to coalesce more.

Re : Scutellinia
Not a species I know but it could be S vitreola

Re : Scutellinia
I will look into it, thanks for your input Malcolm.

Re : Scutellinia
S. vitreola has shorter hairs and the spore ornamentation is a bit different.
I don't know any European species which fits with your collection. The closest species would be S. crinita but the spore ornamentation of your collections is clearly different!
