Flora, 64: 196, 1881. Basionym: Rinodina leprosa subsp. malangica Norman - K. Norske Vid. Selsk. Skr., 5: 342, 1868.

Description: Thallus crustose-subsquamulose, episubstratic, well developed, yellowish brown, olivaceous, grey-brown or grey-green, of contiguous, sublobate areoles/squamules more or less entirely covered in coralloid, (30-)50-60 µm thick blastidia. Apothecia lecanorine, immersed, scattered, (0.2-)0.5-0.8 mm across, with a mostly persistently flat, brown disc, and a thick, usually blastidiate thalline margin. Thalline exciple 80-100 µm wide laterally, cellular, with a thin, indistinct cortex; proper exciple 10-15 µm wide laterally, expanded to 30-35 µm in upper part; epithecium reddish brown, K-; hymenium colourless, 70-90 µm high; paraphyses 2-2.5 µm thick at mid-level, the apical cells up to 5 µm wide; hypothecium colourless, 50-100 µm high. Asci 8-spored, clavate, the K/I+ blue tholus penetrated by a faintly amyloid apical cushion with parallel or diverging flanks, the wall K/I-, surrounded by a K/I+ blue outer layer, Lecanora-type. Ascospores 1-septate, not constricted at septum, brown, ellipsoid, 13-18 x 6-9 µm, with a well-developed torus and smooth walls, Physcia-type, the ontogeny of type A (apical wall thickening after the early septum formation). Photobiont chlorococcoid. Spot tests: K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
Growth form: Crustose
Substrata: bark
