Psammocora obtusangula

(Lamarck, 1816)

Colonies are nodular or form small flattened branches. The latter may be only weakly attached to the substrate. Corallites are circular, not well defined and are not in valleys except at the tips of nodular growths where they are usually crowded. Septa are thick and wedge-shaped and have serrated margins. Columellae are prominent.

Colour: Tan, grey or yellow-brown.

Habitat: Shallow reef environments and rubble.

Abundance: Rare.

Similar species: Psammocora contigua , Psammocora stellata
