Characters: Colonies are flattened, helmet- or dome-shaped and may be several metres across. Corallites are subcerioid or have short, shallow valleys 8-20 millimetres wide, separated by thick walls. Tissue over the septa is usually distinct in colour and/or texture from tissue over the costae. Septa and costae are sturdy, with large blunt teeth.
Colour: In north-west Australia, colonies are a uniform blue-grey or valleys may have concentric cream and green colours. In south-east Asia colonies have a much wider range of colours including bright red, yellow and green.
Similar Species: Corallite details are like those of Parascolymia vitiensis.
Habitat: Lower reef slopes protected from wave action.
Abundance: Sometimes locally common.
Taxonomic Note: The type species of Australomussa Veron, 1985. Considered a species of Parascolymia by Arrigoni, Richards, Chen et al. (2014). However, large colonies lose most morphological similarities with Parascolymia species.
