Description: Thallus foliose, heteromerous, dorsiventral, orange, forming up to 3.5 cm wide rosettes which often coalesce to cover much larger surfaces. Lobes loosely adnate to semi-erect, flattened at least in older parts, up to 5(-8) mm long, 0.3-0.5(-1.5) mm wide, the ends ascending, lip-shaped and blastidiate on lower surface, the blastidia 20-30 µm in diam, often gathered into 40-50(-60) µm wide conblastidia. Lower surface white, smooth to somewhat wrinkled, with abundant, white to yellow rhizines. Upper and lower cortex paraqlectenchymatous; medulla white. Apothecia rare, lecanorine, stipitate, with an orange disc and an often blastidiate thalline margin. Thalline exciple paraplectenchymatous; proper exciple a strongly gelatined plectenchyma with unoriented, short-celled hyphae; epithecium orange-brown, K+ purple-red, c. 10 µm high; hymenium colourless, 20-80 µm high; paraphyses simple or sparingly branched; hypothecium colourless to pale brown, 25-70 µm high. Asci 8-spored, clavate, functionally unitunicate, apically thickened with a broad internal beak, the inner part of apex and external cap I+ blue, Teloschistes-type. Ascospores 2-celled, polarilocular, hyaline, ellipsoid, narrowed at apex, 10.5-15(-16) x 6-7(-8) µm, the equatorial thickening (“septum”) 3.5-5 µm. Pycnidia common, immersed or slightly projecting, slightly darker orange than thallus. Conidia bacilliform, 2.5-4 x 1-1.5 µm. Photobiont chlorococcoid. Spot tests: thallus and apothecia K+ purple-red, C-, KC-, P-, UV+ orange. Chemistry: parietin (major), fallacinal (major), emodin, teloschistin (major) and parietinic acid (chemosyndrome A3 of Søchting 1997).
