Description: Thallus crustose, thin, finely granular, dirty green, greenish grey to greenish black, sometimes eroded and exposing the medulla, giving the thallus a sorediate appearance. Apothecia biatorine, 0.2-0.3 mm across, soon convex and immarginate, at first brown, then often black, usually glossy. Proper exciple thin, of radiating, branched and anastomosing hyphae; epithecium brown, K-, N-, rarely with a greenish tinge and then K-, N+ purple; hymenium colourless, I+ blue; paraphyses strongly branched and anastomosing up to the upper part, immersed in a gelatinous matrix and resembling excipular hyphae; hypothecium colourless. Asci 8-spored, broadly clavate, surrounded by a gelatinous, amyloid sheet, with a well-developed, amyloid tholus containing a widely cylindrical axial body and a poorly developed, bluntly conical ocular chamber, more or less Lecanora-type. Ascospores (4-)7-septate, hyaline, fusiform, thinner at one end, straight or slightly curved, (20-)25-30(-40) x 4-5 μm. Photobiont chlorococcoid, the cells 7-14(-20) μm wide. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
