Description: Thallus crustose, episubstratic, continuous and smooth, rimose or slightly warted, cream-coloured, greenish white or whitish grey, ecorticate, without a distinct prothallus. Apothecia lecideine, black, 0.4-1.5(-2.5) mm across, strongly constricted at base, with a concave to slightly convex, matt, epruinose, minutely roughened disc, and a thick, shiny, persistent or finally excluded proper margin. Proper exciple 80-160 μm thick laterally, layered, with a blue-green or emerald green inner and outer zone, K+ intensifying greenish, N+ purple-red, separated by a median, colourless zone inspersed with oil droplets, composed of radiating, coherent hyphae; epithecium blue-black, bluish green or diffuse olive, up to 10 μm high, K+ intensifying green, N+ purple-red; hymenium colourless or partly pale reddish brown, (90-)120-140(-160) μm high, not inspersed with oil droplets, I+ pale blue; paraphyses lax in K, mostly simple, (1-)1.5(-2) μm thick at mid-level, the apical cells 3-4 μm wide; hypothecium not inspersed with oil droplets, reddish brown to greenish black, K+ reddish violet. Asci 8-spored, cylindrical-clavate, the K/I+ blue tholus penetrated by a faintly amyloid apical cushion with parallel or diverging flanks, the wall K/I-, surrounded by a K/I+ blue outer layer, Lecanora-type. Ascospores 1-septate, often slightly constricted at septum, hyaline, ellipsoid to oblong-ellipsoid, 20-34(-38) x (8-)10-16(-18) μm, the wall 1-2 μm thick. Pycnidia small, black, immersed, with cylindrical conidiogenous cells. Conidia 3-4 x 1.5-2 μm. Photobiont chlorococcoid (according to some authors trentepohlioid, but with low amount of orange pigments), the cells 5-13 μm wide. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: thallus without lichen substances.
