Description: Thallus crustose, episubstratic, rather thick, smooth to uneven, rimose to areolate, whitish to pale brown, the areoles smooth, contiguous, not imbricate, flat to weakly convex, up to 0.5 mm wide, forming a compact crust. Apothecia biatorine, not constricted at base, (0.4-)0.7-1.5(-2) mm across, with an ochraceous orange to finally brown to dark brown, convex, smooth disc and a very thin, soon excluded proper margin. Proper exciple poorly developed, of branched hyphae, colourless to orange-brown, patchily pigmented; epithecium orange-brown to brown, 10-20 µm high, with granular crystals reacting K+ purple-red, N-; hymenium colourless to pale orange, 50-135 µm high; paraphyses coherent, sparingly branched and anastomosing, 2.5-4 µm thick, the apical cells hardly swollen, up to 5 µm wide; hypothecium brown or dark reddish brown, patchily pigmented. Asci 8-spored, clavate, with a well-developed, amyloid tholus containing a more intensely amyloid, indistinct tube structure, without an ocular chamber, approximating the Porpidia- or Psora-types. Ascospores 1-celled, hyaline, ellipsoid to ovoid, thin-walled, (6-)7-11(-14) x (3-)4-6(-7) µm, without a distinct perispore. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-; apothecia K+ purple-red. Chemistry: apothecia with anthraquinones, mainly parietin. Note: a mainly arctic-alpine, probably circumpolar lichen found on base-rich or calciferous siliceous rocks and on dolomite in upland areas; not frequent in Italy, but locally common.
