  Thallus variable, thin and discontinuous to thick and continuous, off-white or greyish white to yellowish white, slightly cracked to areolate, smooth or slightly wrinkled, dull. Soredia and isidia absent. Apothecia numerous, scattered or occasionally confluent, conspicuous, verruciform, flattened-hemispherical, becoming constricted at the base, 0.5–1.5 mm diam. Ostioles pale brown to black, 1–4 per verruca. Ascospores 8 per ascus, uniseriate, ellipsoidal, smooth, 32–65 (–70) × 20–35 µm. Pycnidia rare, 1–3 immersed in verrucae, 0.05 mm diam., black. Conidia narrowly fusiform, c. 10 × 1 µm. CHEMISTRY: Thallus K–, KC–, C–, Pd–; containing 4,5-dichlorolichexanthone (major), 2’-O-methylperlatolic acid (major) and ±2-O-methylperlatolic acid (minor).
  The most common and widely distributed corticolous Pertusaria species in Australia (in all States and Territories except N.T.); it is especially common in the south-east. Possibly endemic, but one doubtful specimen is known from Vanuatu.
