  Thallus adnate, to 5–20 cm wide. Lobes imbricate, 2–8 mm wide; margins crenulate; lobulate or not; apices subrotund. Upper surface yellow-green to pale green, ±rugulose at margins becoming more densely rugose towards centre, dull, sometimes slightly shiny, lacking soredia, dactyls and isidia. Medulla mostly white, often with scattered cream to yellow patches, especially in lower medulla. Lower surface rugulose; rhizines sparse, simple. Apothecia sessile, 2–7 mm wide; disc concave, cinnamon-brown to dark brown; thalline exciple strongly involute, becoming rugulose. Ascospores 12–16 × 8–11 µm. Pycnidia common. Conidia bacilliform, 7–8 × 1 µm. CHEMISTRY: cortex K-, UV-; medulla K-, C-, KC-, P+ deep orange; yellow pigment (when present) in lower medulla K-; containing usnic acid, protocetraric acid (major), caperatic acid, ±atranorin, ±secalonic acid A (in pigmented medulla) and with or without unidentified compounds (trace).
  Very common throughout temperate and subtropical Australia (all States and Territories); also occurs in southern U.S.A. Grows on bark of trees and dead wood, rarely on rock.
