Description: Thallus foliose to subfruticose, loosely attached, forming irregular rosettes or dense tufts to 5 cm across. Lobes 1-5 mm wide, usualy narrower in terricolous forms, dorsiventral, slightly canaliculate or terete, ascending to erect. Upper surface bright yellow in open habitats to greenish yellow in shaded habitats; lower surface pale yellow to tan or whitish, more or less veined, with pale, simple to squarrose rhizines. Upper and lower cortex paraplectenchymatous; medulla yellow, very loose. Apothecia frequent especially in epiphytic forms, lecanorine, submarginal to almost laminal, 2-6 mm across, with a brown to brown- black disc and a smooth, yellow thalline margin. Asci 8-spored, narrowly clavate, with a small axial body and a distinct, K/I+ blue ring-structure in the rather large tholus, approaching the Lecanora-type. Ascospores 1-celled, hyaline, broadly ellipsoid to subglobose, 5-6 x c. 5 μm. Pycnidia frequent, black, marginal to laminal, immersed or on short black projections. Conidia simple, swollen at one end, 6-8 x 1-2 μm. Photobiont chlorococcoid. Spot tests: cortex K-, C-, KC+ yellow, P-; medulla K-, C-, KC-, P-, UV+ blackish red. Chemistry: cortex with usnic acid; cortex and medulla with vulpinic and pinastric acids.
Growth form: Foliose, broad lobed
Photobiont: green algae other than Trentepohlia
Reproductive strategy: mainly asexual, by thallus fragmentation
