Description: Thallus foliose-umbilicate, heteromerous, dorsiventral, polyphyllous, small, to 1 cm wide, but sometimes only 2-3 mm wide, of densely crowded, raised, lobes, usually forming large swards. Lobes with rounded or irregularly incised margins bearing a few flattened, branched, black cilia. Upper surface brownish grey, dull, slightly wrinkled or almost even, sometimes with a few reticulate folds and ridges around the umbo. Lower surface grey-white, tan or pink, even, smooth, almost completely naked or with a few cylindrical, pale, simple rhizinomorphs; thalloconidia absent. Upper cortex 10-20 µm thick; medulla white, 3-layered, the upper and lower layers loose, with an arachnoid plectenchyma, the layer inbetween with a compact plectenchyma; lower cortex 10-20 µm thick, scleroplectenchymatous. Apothecia fairly numerous, black, gyrodisc, markedly stipitate, to 2-3 mm across, convex, with few deep gyri. Epi- and hypothecium dark; hymenium colourless. Asci 8-spored, clavate, thick-walled, with an amyloid apical dome, Umbilicaria-type. Ascospores 1-celled, hyaline, ellipsoid, 8-15 x 3–9 µm. Pycnidia numerous, immersed, bottle-shaped, with a brown wall, and a dark brown ostiole. Conidia c. 3-4 x 0.8 µm. Photobiont chlorococcoid. Spot tests: cortex K-, C-, KC-, P-; medulla K- or K+ yellow turning red, C-, KC- or KC+ faintly red, P- or P+ orange. Chemistry: medulla with variable amounts of norstictic acid and sometimes with very low amounts of gyrophoric and lecanoric acids.
