Thallus: 2-4 cm wide, 200-220 µm thick. Upper surface dark reddish-orange or brownish-orange, dark reddish-violet towards the centre due to the numerous spermogonia, paler yellowish-orange at the periphery. Lobes flat from the centre to the tips but ± convex at the base, 6-7 mm long, 0.5-1 mm wide, but 1-1.5 mm wide at the branching nodes and towards the tips, radiating, very sturdy, margins folded downwards. Upper cortex rather thin, 7-10 µm thick, cells almost rounded to 4 µm diam. Algal zone 50-60 µm thick, continuous, medulla from 60-70 µm thick to 80 µm when hollow, composed of thick scleropletenchymatous bundles 30-40 µm in diam., or of separate hyphae. Lower cortex 10-20 µm thick, paraplectenchymatous in parts but mainly scleroplectenchymatous. Terminal portions of lobes usually narrow (ca. 0.5-1.0 mm wide) and more closely attached to the substrate than in central part. Lower surface yellowish-orange or brownish-orange, exhibiting small veins. Rhizines of Xanthodactylon-type. Apothecia numerous, 0.5-1.7 mm diam., zeorine in section, pedicellate, attenuated at the base, usually not barrel-shaped but young apothecia sometimes immersed in warts; young apothecia slightly paler at the margins, covered by a thin, yellowish pruina; disc reddish-violet to brownish-violet; thalline margin pale yellowish-orange to brownish-orange, sometimes very thick, 0.10-0.25 mm wide, somewhat crenulate when older. Hymenium 65-75 µm high, subhymenium 10-20 µm thick; paraphyses unbranched, 1.5-2.0 µm diam., slightly widened towards the tips, to 3-4 µm diam., oil cells and oil droplets not seen; asci 8-spored. Ascospores of Xanthoria-type, of uniform size within and and outside the asci, from almost spherical to elongate ellipsoid, (8-)9-12 x 5-7(-8) µm in water [(8-)10-12(-14) x (5-)6-8 µm in K], septum 3-5(-6) µm thick in water [slightly wider, (3-)4-7 µm in K].
