Thallus very loosely appressed, or raised off substrate, loosely adnate, attached mostly only centrally, 1.5-3 cm diam., saxicolous. Lobes 0.2-1 mm broad, flat or subconvex, sublinear and ± discrete, to rather short and loosely imbricate. Upper surface yellowish-brown to dark brown, paler at apices, ± smooth, becoming wrinkled centrally, some areas with numerous, small, blackened pits (senescent pycnidia) without isidia. Lower surface pale tan to brown, darker at apices, smooth to wrinkled, without rhizines, attached by occasional central loboid holdfasts. Apothecia numerous, sessile, concave to 5 mm diam., margins entire to crenulate. Ascospores ellipsoid, 8-10.5 × 4.5-6 µm. Pycnidia numerous, senescing to form small black pits. Conidia 6.5-8 × 1 µm, bifusiform to rod-shaped. Chemistry: Cortex K-, HNO3+ dark blue-green; medulla K+ yellow-orange, C-, KC+ orange, Pd+ red-orange. Protocetraric and fumarprotocetraric acids.
