Description: Thallus crustose, continuous or rimose-areolate, yellowish to yellowish white, somehow shiny, rarely delimited by a dark prothallus. Medulla white, I-. Apothecia lecideine (rarely appearing lecanorine when very young), at first immersed, then subsessile, rounded to slightly irregular in outline, 0.4-1.5(-2.5) mm across, with a shining black, flat to convex disc, and a black, soon excluded, sometimes slightly white-pruinose proper margin; thalline margin present only in very young apothecia and very soon excluded. Proper exciple dark blue-green in outer part, colourless within, the pigmented parts, N+ red; epithecium green to dark blue-green or greenish black, N+ red; hymenium colourless, 50-75 µm high; paraphyses simple or sparingly branched and anastomosing, 1.5-2.5 µm thick at mid-level, the apical cells swollen, 3.5-5(-6) µm wide; hypothecium colourless, 80-200 µm high. Asci 8-spored, clavate, very thin-walled, with a K/I+ blue, tall tholus penetrated by a faintly amyloid apical cushion, the wall K/I-, surrounded by a blue outer layer, Lecanora-type. Ascospores 1-celled, hyaline, ellipsoid, (8-)10-13(-14) x (4.5-)6-7.5 µm. Pycnidia black, immersed. Conidia thread-like, curved, 11-20(-25) x 0.5-1 µm. Photobiont chlorococcoid. Spot tests: cortex K- or K+ yellow, C-, KC- or KC+ yellow, P- or P+ pale yellow. Chemistry: usnic acid and atranorin, both in variable concentrations.
