Verrill, 1864
Description: Polyps are circular, up to 160 millimetres diameter and generally flat. Septa are densely packed. Septal teeth and costal spines are small, giving septa a smooth appearance. Tentacular lobes are not formed or are minute. The undersurface is usually without pits.
Color: Usually brown, sometimes with a contrasting perimeter.
Habitat: Reef slopes and lagoons.
Abundance: Common.
Similar Species: Fungia repanda, which has coarser septal teeth, pits between the costae and is usually more arched. See also F. spinifer and F. scabra.
