Description: Thallus foliose, heteromerous, dorsiventral, adnate, forming 1-7(-15) cm wide rosettes. Lobes elongate, 1-3(-4) mm wide, often slightly channelled. Upper surface brown to black-brown, usually glossy, with small, often poorly evident, usually laminal, white pseudocyphellae and knobby pycnidial warts along the margins; lower surface pale or turning brown in central parts, with scattered, pale to dark brown rhizines. Upper cortex paraplectenchymatous, with a non-pored epicortex, the cell walls containing Cetraria-type lichenan; medulla white. Apothecia lecanorine, submarginal, located at the tips of short lobes, to 1-5(-7) mm across, with a smooth, concave, brown disc and a thin, inflexed usually smooth, often crenulate thalline margin. Epithecium brownish; hymenium and hypothecium colourless. Asci 8-spored, narrowly clavate, with a small axial body and a distinct, K/I+ blue ring-structure in the rather large tholus, approaching the Lecanora-type. Ascospores 1-celled, hyaline, ellipsoid, 7-10 x 4-6.5 μm. Pycnidia common, black, immersed in slightly raised, knobby, mostly marginal warts. Conidia short-bacilliform or fusiform, 3-6 x 1-1.5 μm. Photobiont chlorococcoid. Spot tests: upper cortex K-, C-, KC-, P-; medulla K-, C-, KC- or rarely KC+ red, P-. Chemistry: medulla with α-collatolic acid or alectoronic acid.
