Description: Thallus crustose, episubstratic, , grey, grey-brown or greenish brown, warted-areolate, of (0-1-)0.2-0.5 mm wide, weakly to strongly convex, often crenate, sometimes subcoralloid areoles with more or less elevated margins. Apothecia biatorine, round to flexuose in outline, rarely tuberculate, sessile and constricted at base, 0.3-0.8(-1.4) mm across, with a reddish to blackish brown, rarely ochraceous, flat to strongly convex, epruinose disc, and a distinct, not or only weakly prominent, finally sometimes excluded proper margin. Proper exciple 35-90 µm wide laterally, orange to reddish brown in outer part, colourless to pale orange-brown within; epithecium orange-brown to dark reddish brown, K-; hymenium colourless, 60-90 µm high; paraphyses rather lax, sparingly branched and anastomosing, 0.7-1 µm thick at mid-level, the apical cells to 3 µm wide; hypothecium colourless to pale yellowish, 70-150(-200) µm high. Asci 8-spored, cylindrical-clavate, the I+ blue tholus with a wide, I+ dark blue tube structure that expands towards the top, without a pale axial body, approaching the Micarea-type. Ascospores 1-celled, hyaline, ellipsoid to ovoid (9.5)11-15(-18) x (4-)6-8(-9) µm. Photobiont chlorococcoid. Spot tests: thallus K- or K+ faintly yellow, C-, KC- P- or P+ faintly yellow, UV+ yellow-orange. Chemistry thallus with different xanthones.
Note: on terricolous mosses and plant debris over siliceous substrata, sometimes also on the bark of subalpine shrubs, with optimum near treeline; probably restricted to the Alps in Italy.
