| Thalluscrustose, leprose, creamy white, grey-white or pale yellow-grey, diffuse or delimited, forming extensive irregularly spreading patches to 10 cm wide, or in small irregularly rounded colonies 5–20 mm wide which eventually coalesce. Margin usually delimited, often with well-defined lobes 0.2–1.0 mm wide, raised at the margins. Soredia fine, dispersed or forming a thick continuous layer, ±globose, 15–40 μm wide, commonly aggregated in consoredia 150–200 μm wide, with long projecting hyphae along the margins (to 600 µm long); shorter projecting hyphae within (20–125 μm long). Medulla absent or patchy and white. Hyphae 1.5–3.0 μm thick. Lower surface not apparent.Photobiont cells ±spherical,
7–12 μm diam. Hypothallus thin and white or not apparent. CHEMISTRY: Thallus K+ yellow, C–, KC–, P+ yellow, UV+ bright blue; containing squamatic acid (major), baeomycesic acid (major or minor), unknown fatty acid (major or minor), ±barbatic acid (trace), ±hypothamnolic acid (trace), ±subbaeomycesic acid (trace), ±subsquamatic acid (trace), ±protocetraric acid (trace). |

| This endemic species occurs on the trunks of trees, on wood and on rocks in subtropical rainforest, monsoon forest and in open woodland at elevations of 60–1400 m in northern and eastern Australia (tropical W.A. and N.T. and eastern N.S.W.). | ||
