Characters: Colonies are thin plates or encrusting with a flat surface. Corallites are large for Psammocora, are regularly distributed and have distinctive exsert primary septo-costae which may be petaloid or meandering.
Colour: Pale or dark brown or green, frequently mottled.
Similar Species: Resembles Coscinaraea wellsi more than other Psammocora.
Habitat: Protected reef environments especially in high latitudes.
Abundance: Uncommon.
Taxonomic Note: Placed in genus Cycloseris by Benzoni, Arrigoni, Stefani et al. (2012) based mainly on genetic evidence. It is retained here as a Psammocora because it does not match the distinctive genus-level characters of Cycloseris, which represent predominantly solitary, unattached mushroom corals. It may warrant a separate generic designation, along with Coscinaraea wellsi, see 'Overview of coral taxonomy'.
