Characters: Colonies are encrusting and do not have a conspicuous central corallite. The surface may be folded and sometimes forms tubes. Corallites are inclined towards the colony margins and are distributed irregularly. Corallites have small openings. Septo-costae are granulated and alternate. Those of adjacent corallites commonly join to form angular lines. Corallite-like mounds commonly occur between corallites.
Colour: Brown with white margins.
Similar species: Leptoseris scabra, which does not have corallite-like mounds between corallites and has strongly alternating septo-costae which do not form angles. See also L. hawaiiensis.
