Characters: Colonies are loosely attached or free-living, encrusting or laminar, and unifacial, with irregularly lobed margins and an irregularly contorted surface. There is no central corallite. Peripheral corallites are inclined towards the plate margins. Septo-costae are similar to those of Halomitra.
Colour: Grey-brown with white margins.
Similar Species: This species combines various characters of Lithophyllon, Podabacia and Halomitra. Corallites are smaller, less regular and more inclined on the colony surface than are those of P. motuporensis.
Habitat: Shallow, horizontal, protected, partly turbid environments.
Abundance: Rare.
