Descriptions
Thallus foliose, spreading, closely attached, rosette-forming to ± irregular, 1-3(-5) cm diam., saxicolous. Lobes subdichotomously to irregularly branched, mainly convex, 0.1-1.2(-1.6) mm wide, 3-5(-8) mm long, 100-300(-450) µm thick, ± discrete at margins, often widely separated, to ± contiguous, imbricate centrally, margins entire, noticeably downturned, apices rounded or shallowly incised, somewhat thickened, often with small, sparse to numerous, subapical, adventitious globose lobules or branchlets. Upper surface matt, smooth or minutely roughened or ± scabrid in parts, coarsely undulate-plicate, coriaceous, not pitted or faveolate, deep yellow to orange, rarely orange- red. Lower surface white at margins, pale pinkish-buff or brownish centrally, glossy or dull, wrinkled-puckered, sparsely rhizinate. Rhizines rare, short, pale brownish-pink or blackened, less than 0.1 mm long, fasciculate. Apothecia sparse to numerous, mainly central, solitary or clustered, rounded or irregularly deformed through mutual pressure, 0.1-2.0 mm diam., innate at first, slowly emergent with a thick, rounded rim, becoming sessile, disc concave at first, often hidden by inflexed margins, normally plane to subconvex-undulate at maturity, deep orange to orange-red, darker than margins or thallus, minutely roughened, margins persistent, entire to subcrenulate, inflexed at first, thinner at maturity, concolorous with thallus. Hymenium colourless, 50-65 µm tall. Apices of paraphyses clavate, to 6-7 µm diam. Ascospores (10-)12-15 × 6.5-9 µm.
