(Lamarck, 1816)

Colonies are encrusting or thin unifacial laminae but are sometimes submassive or columnar. Corallites are usually widely spaced and circular, with pillar-like columellae and smooth alternating septo-costae. They may occur in concentric rows.

Colour: Grey, brown, pink, purple, green or yellow, sometimes mottled.

Habitat: Most reef environments.

Abundance: Common.

Similar species: Pavona gigantea
