Description: Thallus crustose, endo- to episubstratic in non-sorediate parts, continuous to more or less distinctly areolate, forming regular or irregular, up to 10 cm wide patches, usually delimited by a dark, bluish to brown prothallus, the blue pigment N+ red. Areoles 0.1-0.3 mm wide, convex, green to pale brown, soon bursting apically into minute, irregularly punctiform, 0.1(-0.3) mm wide, mostly flat soralia which rarely coalesce into a subleprose crust; soredia farinose, up to 20-30 μm in diam, the external ones brownish, the internal ones pale greenish. Apothecia not always present, biatorine, up to 0.6 mm across, the disc flat to strongly convex, blackish but often faintly pruinose and appearing bluish grey, lead-grey or grey-black, rarely with a brownish hue, the proper margin soon excluded. Proper exciple more or less colourless, of radiating hyphae; epithecium pale olive-green to greenish brown; hymenium colourless to bluish green in upper part; paraphyses strongly coherent, sparingly branched and anastomosing; hypothecium pale olive-brown. 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-celled, hyaline, ellipsoid, 9-17 x 4-7.5 µm. Photobiont chlorococcoid. Spot tests: thallus and soralia K- (or soralia K+ very pale yellow), C-, KC-, P-, UV+ white. Chemistry: sphaerophorin (major), isosphaeric acid (traces).
