Description: Thallus crustose, episubstratic, continuous to areolate-subsquamulose, rather thick, chestnut-brown, pale reddish brown, rarely pale grey or olivaceous, often with poorly developed marginal lobes, often delimited by a black prothallus (especially when young). Areoles, when well-developed, irregularly polygonal to round, 0.2-2.5 mm wide, flat to convex, smooth to coarsely warted, the marginal ones often elongated and lobe-like. Cortex 20-30(-40) µm thick, composed of anticlinally arranged hyphae with brown-pigmented caps, sometimes inspersed with small, brown crystals dissolving in K (lobaric acid), or minute crystals of gyrophoric and lecanoric acids; epinecral layer usually well-developed, hyaline, (5-)10-15(-25) µm thick; medulla white, often with crystals, I-. Apothecia lecanorine, adnate to sessile and constricted at base, round to subangular, (0.5-)0.75-1.75(-2.5) mm across, with a brown to brownish black, concave to convex, epruinose disc, and a usually slightly paler, thick, entire or crenulate, shiny, usually persistent thalline margin. Thalline exciple (50-)100(-200) μm wide, corticate, with a distinct medulla filled with algal cells; proper exciple forming a up to 100 µm thick cupular layer below the hypothecium; epithecium brown, 20-30 µm thick; hymenium colourless or yellowish, (50-)60-70(-90) µm high; paraphyses coherent in water, distinct in K, c. 2-2.5 μm thick, with slightly wider apices covered by a swollen gelatinous hood; hypothecium colourless or pale yellow, up to 100 μm high. Asci 8-spored, clavate, approaching the Lecanora-type, with a well-developed amyloid tholus and a distinct, non-amyloid axial mass. Ascospores 1-celled, hyaline, oblong-ellipsoid to narrowly ellipsoid with rounded ends, thin-walled, (7.5-)9.5-13(-16) x (2.5-)3-4(-4.5) µm, with 2-3(-6), very thin, hyaline setae at each end. Pycnidia usually abundant, globose to oblong, the ostiole dark brown to black. Conidia simple, bacilliform, straight to slightly curved, (5-)7-11(-14) µm long. Photobiont chlorococcoid. Spot tests: medulla K+ pale to dirty yellow, C- or C+ pink to red, KC- or KC+ red to violet, UV+ white, or UV-; brown pigment in cortex, pycnidial wall around the ostiole and epithecium C+ fleeting bluish-grey, followed by very pale pink, K+ yellowish-brown. Chemistry: several chemotypes with lobaric acid (and several related substances), gyrophoric acid, lecanoric acid, and several fatty acids.
Note: a Mediterranean-Macaronesian, chemically variable species found on siliceous rocks at relatively low altitudes. For further details see Barbero & al. (2006) and Singh & al. (2015).
