Mitt. bot. Staatss. München, 23: 383, 1987. Basionym: Lecidea fuscoatra var. deusta Stenh. - Nov. Sched. Crit. Lich. Suec., 14: 9, 1833.
Synonyms: Lecidea deustata Zahlbr.; Lecidea secernens H. Magn.
Description: Thallus crustose, episubstratic, 0.1-0.4 mm thick, areolate, consisting of angular to irregular, (0.3-)0.5-1(-1.5) mm wide, slightly concave to slightly convex, dark brown to black-brown, glossy areoles with whitish to finally blackish margins, more or less scattered on a conspicuous black hypothallus. Cortex overlain by a thick epinecral layer; medulla white, I-. Apothecia rare, lecideine, at first immersed, then slightly prominent, (0.4-)0.5-0.9(-1.2) mm across, with a flat to slightly convex, black, epruinose disc and a thin, rarely grey-pruinose proper margin. Proper exciple grey-brown to aeruginose green in outer part, pale grey within; epithecium blackish brown to olive-brown; hymenium colourless to yellowish, (30-)50-60 µm high, I+ blue; paraphyses sparingly branched and more or less anastomosing, 1.5-2 µm thick at mid-level, the apical cell clavate, 3-5.5 µm wide, with a dark cap; hypothecium colourless, yellowish or pale grey. Asci 8-spored, clavate, approaching the Lecanora-type, but with a weakly amyloid tholus, lacking an amyloid zone above the axial body and with a thin outer amyloid wall layer. Ascospores 1-celled, hyaline, ellipsoid to oblong, (8-)10-12(-14) x (3.5-)4-5.5(-7) µm. Pycnidia black, immersed. Conidia thread-like, curved, (18-)25-35 x (0.5)0.8-1 µm. Photobiont chlorococcoid. Spot tests: thallus and medulla K-, C-, KC-, P-. Chemistry: miriquidic acid, rarely additional lobaric acid.
