Thallus: foliose, forming medium-sized to large rosettes up to 3.5 cm wide or larger colonies, loosely adnate (to semi-erect), lobate; lobes dorsiventral, flattened to convex, 0.3-1.4 mm wide; tips truncate to rotund, 0.3-0.9 mm wide; upper surface bright orange to orange, smooth to shiny, sorediate; soredia granular, blastidious, in marginal to submarginal or laminal soralia; medulla white, reticulate, with short hyphae; lower surface white, smooth to somewhat wrinkled, with abundant, white to yellow rhizines. Apothecia rare but sometimes abundant, laminal, stipitate, up to 3 mm in diam.; margin: smooth but often sorediate, with cilia; disc: orange; epihymenium: brown, c. 10 µm thick; hymenium hyaline below, 20-80 µm tall; paraphyses simple or slightly branched, cylindrical, septate; hypothecium hyaline to pale brown, 25-70 µm thick; asci clavate, 8-spored. Ascospores ellipsoid, polarilocular, hyaline, 13-16.5 x 6.5-8 µm; septum 3-5.5 µm wide. Pycnidia common, immersed or slightly protruding, darker than upper surface; conidia bacilliform, 2.5-4 x 1-1.5 µm (Nash et al. 2001: xx).
