Description: Thallus crustose to subsquamulose, episubstratic, to 0.6 mm thick, of 0.2-0.5 mm wide, round areoles divided by deep cracks, the surface minutely nodulose, whitish, yellow-brown or rarely dark brown, becoming green when wet, epruinose, without a distinct prothallus. Cortex to c. 50 μm thick. Apothecia lecanorine, broadly to narrowly sessile, round, 0.3-0.5(-0.8) mm across, with a flat to convex, pale brown to dark brown, rarely white-pruinose disc which becomes translucent and dark-spotted when wet, and a pale grey to pale brown, rather thick, persistent thalline margin. Thalline exciple (40-)70-100 μm thick laterally, distincly corticate at least at base, usually with a 10-20 μm thick hyaline outer layer, rich in algae; proper exciple colourless or brownish in outer and upper parts; epithecium pale orange-brown to dark brown-spotted, the pigment often extending deep into the hymenium; hymenium colourless in lower part, (55-)60-75(-85) µm high; paraphyses coherent, 2-3 µm thick at mid level, the apical cell colourless or externally pink-brown-pigmented, at least some of them strongly swollen, to 5(-7) µm wide; hypothecium colourless to rarely pale yellow, not inspersed with oil droplets, 50-80 µm high. Asci 8-spored, narrowly clavate, with a K/I+ blue tholus and a central non-amyloid area, Bacidia-type. Ascospores (0-)1-septate, hyaline straight, not constricted at septum, oblong-ellipsoid, (10-)11-17(-19) x (4-)4.5-6(-7.5) µm, thin-walled, without a gelatinous perispore. Pycnidia rare, immersed, the wall colourless, but red brown near ostiole. Conidia thread-like, strongly curved, 14-20 x c. 0.8 µm. Photobiont chlorococcoid. Spot tests: thallus K-, C-, KC-, P-, UV-. Chemistry: without lichen substances. Note: a mild-temperate calcicolous species, often found on man-made, more or less calciferous substrata; in the past confused with other species, especially L. erysibe, which is truly blastidiate.
