Description: Thallus foliose to subfruticose, of prostrate to ascending, flattened, strap-shaped 1-10(-20) mm wide, several cm long, dichotomously branched lobes which are very variable in size and shape. Upper surface grey to brown in exposed situations, matt, with cylindrical, simple to branched isidia, rarely also with whitish, orbicular, convex soralia; lower surface usually channelled, black in older parts, white near the tips, without rhizines. Upper cortex with a pored epicortex, palisade paraplectenchymatous; medulla white, rather loose, the cell walls containing Cetraria-type lichenan. Apothecia very rare, lecanorine, up to 15 mm across, more or less stalked, often irregular in form and sometimes with split margins, with a brown disc. Epithecium brown; hymenium and hypothecium colourless. Asci 8-spored, elongate-clavate, very thin-walled, with a K/I+ blue, tall tholus penetrated by a faintly amyloid apical cushion, the wall K/I-, surrounded by a K/I+ blue outer layer, Lecanora-type. Ascospores 1-celled, hyaline, ellipsoid, 7-10 x 4-6 µm. Pycnidia rare, immersed, black. Conidia sublageniform, 5-7 x c. 1 µm. Photobiont: chlorococcoid. Spot tests: cortex K+ yellow, C-, KC-, P-; medulla K-, C-, KC+ faintly pink, P-, UV-. Chemistry: cortex with atranorin and chloroatranorin, medulla with physodic acid.
Growth form: Foliose, broad lobed
Photobiont: green algae other than Trentepohlia
