Description: Thallus crustose, thinly episubstratic, brownish green, darker and less evident when dry, subgelatinous when wet, continuous. Apothecia lecideine, subsessile, 0.2-0.4 mm across, with a pale brown to finally brown-black (paler when wet), strongly concave to finally flat disc, and a thick, brown proper margin. Proper exciple brownish in outer part, colourless within; epithecium colourless to very pale yellowish brown; hymenium colourless, 90-120 µm high, I+ yellowish to reddish brown; paraphyses simple, c. 1 µm thick, not thickened at apex; hypothecium colourless. Asci (4-)8-spored, thin-walled, apically thickened, with a small ocular chamber. Ascospores muriform, hyaline, ellipsoid, with a thin halo, (15-)17-20(-22) x 7-10 µm. Photobiont chlorococcoid, Cystococcus/Leptosira-like. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.

Note: on acid to subneutral soil and plant debris; rare in the European orobiomes, with a single record from the Alps (Carinthia, Austria); to be looked for in Italy.
