Description: Thallus foliose-umbilicate, heteromerous, dorsiventral, monophyllous, usually large to very large, 3-10(-20) cm diam., dull brown but often coarsely white-pruinose when dry, green-brown when wet, attached by a stout, central holdfast. Upper surface with numerous conspicuous, convex, round to oval pustules, the margins becoming more or less eroded; isidia coralloid, dark, arranged in clusters, especially around cracks of the upper cortex. Lower surface grey to brown-black, reticulate, with broad depressions corresponding to the pustules, erhizinate; thalloconidia absent. Apothecia very rare, 1-3 mm across, with a black, flat, smooth disc and a persistent, smooth or partially isidiate true exciple. Epithecium black-brown; hymenium colourless, c. 100 µm high; paraphyses simple or sparingly branched, with enlarged apical cells; hypothecium dark brown, to 160 µm high. Asci 1(-2)-spored, elongate-clavate, thick-walled, with a K/I+ blue apical dome. Ascospores muriform, at fist hyaline, then brown, 28-70 x 18-34 μm. Pycnidia black, immersed, bottle-shaped, with a brown wall of isodiametric cells. Conidia bacilliform, 2.5-3 x c. 1 μm. Photobiont chlorococcoid. Spot tests: cortex K-, C-, KC-, P-; medulla K-, C+ red, KC+ red, P-, UV-. Chemistry: medulla with gyrophoric acid. Note: a temperate to boreal-montane, circumpolar species found on periodically wetted, but rapidly drying surfaces of basic siliceous rocks, usually in seepage tracks, with a wide altitudinal range, but usually absent above treeline. The species is widespread both in the Alps and in the mountains of Mediterranean Italy.
