Characters: Polyps are circular, up to 200 millimetres diameter and flat or with a small central dome. Septa are of markedly different sizes and have large triangular to columnar teeth with a central rib and which form a regular pattern. Tentacular lobes are usually not developed. Costae are widely spaced, the larger having simple spines. The undersurface has pits between the costae.
Colour: Brown, sometimes with radiating stripes, with white tentacular lobes.
Similar Species: Fungia horrida, which does not have regular triangular septal teeth.
Habitat: Reef slopes and lagoons.
Abundance: Common in the western Indian Ocean and Red Sea, uncommon elsewhere.
Taxonomic Note: Considered a synonym of Fungia horrida by Hoeksema (1989, this species lacks defining characters, but is commonly seen in situ where the septal teeth are distinctive.
