Bull. Soc. Bot. France, 30: 370, 1883. Basionym: Lecanora muralis var. dispersoareolata Schaer. - Lich. Helv. Spicil., 9: 418, 1840.
Synonyms: Placodium dispersoareolatum (Schaer.) Körb.; Protoparmeliopsis dispersoareolata (Schaer.) S.Y. Kondr.; Squamaria dispersoareolata (Schaer.) Anzi
Description: Thallus crustose to subsquamulose, episubstratic, yellowish green, somehow shiny, rarely pruinose, very variable in shape and size, without a black hypo-/prothallus, the areoles flat to convex, often clustered in small groups, the marginal ones usually lobulate, rarely forming up to 5 cm wide, irregular rosettes; marginal lobules to 1-2 mm long and wide, flat to slightly convex, often with a thick, blue-grey margin of medullary hyphae. Cortex thick, strongly inspersed with yellowish crystals; medulla white, rather lax. Apothecia lecanorine, at first immersed, then sessile, 1 to several per areole, round or deformed by mutual compression, 2-5(-6) mm across, finally often larger than the areoles, with a flat to strongly convex, pale to medium red-brown, usually epruinose disc, and an entire to crenulate, sometimes blue-black-spotted thalline margin. Thalline exciple very thick in lower part; epithecium brownish; hymenium colourless, c. 70 µm high, the upper 20 µm inspersed with oil droplets; hypothecium colourless. Asci 8-spored, clavate, very thin-walled, with a K/I+ blue, tall tholus penetrated by a faintly amyloid apical cushion, the wall K/I-, surrounded by a blue outer layer, Lecanora-type. Ascospores 1-celled, hyaline, narrowly ellipsoid, 12-18 x 4-7 µm. Photobiont chlorococcoid. Spot tests: thallus (and apothecial margin) K- or K+ brownish yellow, C-, KC+ pale yellow, P- or P+ orange-red. Chemistry: usnic acid, rangiformic acid, sometimes low amounts of protocetraric and psoromic acids.
