Thallus dorsiventral, heteromerous, foliose, lobate to occasionally subcrustose or subfruticose, loosely to closely attached, saxicolous or terricolous. Lobes 0.1-5 mm diam., short and rounded to linear-elongate, flat to distinctly convex to pulvinate or subpannose. Upper surface brown or brownish-black, with or without isidia, lacking pseudocyphellae and soredia or very rarely sorediate. Photobiont green, . Medulla white, lower surface ± flat to weakly channelled. Rhizinate or not. Rhizines simple or once-branched towards tips.
