Characters: Colonies are encrusting or are low mounds up to one metre across. Corallites are polygonal, 2-4 millimetres diameter. Septa are neatly arranged: 30-35 at the wall, fusing in neat fan-like groups so that 10-15 fuse with the columella. Walls have a fine ridge along their tops.
Colour: Pale tan or with dark centres and white corallite walls.
Similar Species: Pseudosiderastrea tayamai, which has a similar growth-form and appearance, but septa have saw-like teeth. Superficially similar to some monocentric Pavona.
Habitat: Shallow reef environments or sandy lagoons. Colonies are often partly buried in sand.
Abundance: Uncommon.
