Upper surface yellow-green, emaculate, smooth and shiny at margins, rugose and cracked in centre, without soredia; isidia moderately dense to dense, often forming a dense areolate crust, cylindrical, extensively coralloid-branched, robust, to 2.5 mm tall, broad, 0.1–0.3 mm wide, apices syncorticate. Medulla white. Lower surface smooth and shiny at margins, matt and rugose at centre, black with a narrow brown naked marginal zone; rhizines sparse, simple, black. Apothecia rare, sessile, 2–6 (–8) mm wide; disc smooth, deeply concave, becoming shallowly convex, red-brown; thalline exciple rugose, shiny, becoming conspicuously isidiate. Ascospores 8–11 × 4–6 µm. Pycnidia not seen. CHEMISTRY: cortex K-, UV-; medulla K+ yellow then dark red, C-, KC+ red, P+ orange; containing usnic acid, salazinic acid (major) and consalazinic acid.
