Lichenogr. Univ.: 396, 1810. Basionym: Lichen epibryon Ach. - Lichenogr. Suec. Prodr.: 79, 1799.
Synonyms: Lecanora subfusca var. hypnorum Rabenh.
Description: Thallus crustose, episubstratic, whitish to pale grey, continuous to warted. Apothecia lecanorine, more or less round or irregular in outline, sessile, strongly constricted to almost substipitate, 0.5-2(-3) mm across, with a reddish brown, often somewhat shiny, epruinose, mostly flat disc and a thick, smooth to crenulate-undulate thalline margin. Thalline exciple to 100 µm thick, containing small, irregular crystals visible under polarized light and not dissolving in K; epithecium red-brown, without crystals, sometimes with small oil droplets; hymenium colourless, 60-90 µm high; paraphyses simple or sparingly branched in upper part, 1.5-2 µm thick at mid-level, the apical cells slightly thickened, to 3.5 µm wide; 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, ellipsoid or narrowly ellipsoid, (11-)12-17(-19) x (6-)7-8(-10) µm. Photobiont chlorococcoid. Spot tests: thallus K+ yellow, C-, KC-, P- or P+ slowly and faintly yellow, UV-. Chemistry: atranorin and variable amounts of zeorin.
