Description: Thallus crustose, episubstratic, up to 0.25 mm thick, continuous to rimose-areolate, pale glaucous grey to dark grey, rarely delimited by a dark prothallus. Apothecia lecanorine, adnate to sessile, (0.5-)0.7-1-(1.2) mm across, with a flat to finally slightly convex, dark brown to black disc and an entire to crenulate, persistent thalline margin. Proper exciple dark brown to blue-green in outer part, the blue-green parts N+ red: epithecium dark brown to blue-green and then N+ red; hymenium colourless to olivaceous, 80-100 μm high; paraphyses branched in upper part, 1-2 µm thick at mid-level, the apical cells 4-7 µm wide, with a dark cap; hypothecium colourless, up to 250 μm high. Asci 8-spored, 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, brown, ellipsoid, (15-)16-22(-29) x (6-)8-12(-15) μm, Pachysporaria-type, with thick walls and rounded lumina, when young showing tendencies towards the Physcia-type, the wall warted, the tholus well-developed, the ontogeny of type A (apical wall thickening after septum formation). Pycnidia black, immersed. Conidia bacilliform, 3-6 x 1-1.5 μm. Photobiont chlorococcoid. Spot tests: thallus K+ yellow, C-, KC-, P- or P+ faintly yellow. Chemistry: atranorin, sometimes also chloroatranorin and zeorin.
