Description: Thallus crustose, episubstratic, 0.5-1.7 mm thick, of flat to convex, 0.2-1(-2) mm wide, pale to dark brown, smooth, shiny areoles developing on a dark hypothallus, forming up to 8(-10) cm wide orbicular patches. Cortex brown in upper part, 12-35 µm thick, with a thick epinecral layer; medulla white, I-. Apothecia lecideine, rounded, sessile and constricted at base, (0.3-)1-1.5(-3.5) mm across, with a blackish brown to black, flat to convex, epruinose disc, and a thin, raised, finally sometimes excluded proper margin. Proper exciple grey, dark green or olivaceous brown in outer part, paler within; epithecium brownish, olive brown to greenish, 10-15 µm thick; hymenium colourless or olivaceous green in upper part, 50-70 µm high, I+ blue; paraphyses coherent, mostly branched, rarely anastomosing, 1.7-2.3 µm thick at mid-level, the apical cells up to 3.5 µm wide; hypothecium colourless. Asci 8-spored, broadly cylindrical to subclavate, more or less of the Lecanora-type, but with a weakly defined apical cushion and ocular chamber. Ascospores 1-celled, hyaline, ellipsoid to oblong, 10-19 x 4.5-7 µm. Pycnidia dark, immersed. Conidia thread-like, curved, 18-26 x c. 1 µm. Photobiont chlorococcoid. Spot tests: cortex K+ yellow, C-, KC-, P+ orange. Chemistry: miriquidic and stictic acids.
Note: a circumpolar, arctic-alpine species found on mineral-rich rocks wetted by rain in wind-exposed situations, such as on peaks and windy ridges in the Alps, usually near or above treeline, reaching the nival belt. The specific epithet is often spelled garovaglioi, but the latinised name of Santo Garovaglio (who wrote most of his works in Latin) was Garovaglius, whose genitive is garovaglii.
