Description: Thallus squamulose, heteromerous, pale greenish grey to brownish when dry, green when wet. Squamules 0.5-2(-3) mm broad, 0.15-0.25 mm thick, usually weakly to deeply lobed, convex, smooth, scattered to contiguous, not imbricate, fully adnate or rarely with a slightly up-turned margin. Lower surface black, with conspicuous black rhizines anchoring and linking the squamules, and colourless to dark rhizohyphae; rhizines moderately to richly branched, to several mm long, with a carbonaceous envelope and a colourless core. Upper cortex pseudoparenchymatous, 30-70 μm thick, overlain by an epinecral layer; lower cortex more or less paraplectenchymatous in upper part, brown-black; medulla white, subparaplectenchymatous, composed of rounded cells. Perithecia frequent, subglobose, fully immersed, up to 0.4 mm across, without involucrellum. Exciple brown-black to black throughout, 20-30 μm thick; hymenium colourless, I+ brown-red, filled with subglobose to ellipsoid-oblong hymenial algae; hamathecium of 40-60 µm long periphyses, paraphyses absent. Asci (1-)2-spored, bitunicate, thick-walled, clavate to cylindrical-clavate, bitunicate, with a fissitunicate dehiscence, thin-walled, the wall non-amyloid. Ascospores muriform, at first hyaline, then pigmented, ellipsoid, (16-)28-60(-75) x 11-26 μm, the apical spore smaller. Pycnidia black, immersed, to 0.3 mm across. Conidia hyaline, bacilliform, 3-5 x 0.8-1 μm. Photobiont chlorococcoid (Diplosphaera), present in both thallus and hymenium. Spot tests: cortex and medulla K-, C-, KC-, P-, UV-. Chemistry: without lichen substances.
