Description: Thallus foliose, heteromerous, dorsiventral, narrow-lobed, closely adnate in the center, forming orbicular to usually irregular, 1-3 cm wide rosettes, the individual thalli often coalescing to cover larger surfaces. Lobes grey to pale brown in sun-forms, 0.3-1 mm wide, flat to weakly concave, epruinose, ascending at tips, with terminal, labriform soralia with granulose soredia which are mostly >40 µm in diam. Lower surface black, with abundant, black, mostly simple rhizines. Upper cortex paraplectenchymatous, 12-24 µm thick; medulla yellow to orange-red; lower cortex paraplectenchymatous, 14-24 µm thick. Apothecia very rare, lecanorine. Asci 8-spored, clavate, the K/I+ blue tholus penetrated by a faintly amyloid apical cushion with parallel or diverging flanks, the wall K/I-, surrounded by a K/I+ blue outer layer, Lecanora-type. Ascospores 1-septate, brown, ellipsoid, 23-39 x 10-16 μm, Pachysporaria-type. Pycnidia rare. Photobiont chlorococcoid. Spot tests: cortex K-, C-, KC-, P-, UV-; medulla K+ red, C+ red. Chemistry: medulla with skyrin and fatty acids.
