Characters: Colonies are submassive. Corallites are situated at the bottom of depressions or are in short non-meandering valleys. Walls have acute tops. Primary septo-costae are petaloid but are not exsert.
Colour: Uniform grey, brown or sometimes bright colours.
Similar species: Psammocora profundacella, which has less valley formation, more distinct corallite centres and less acute walls. Superficially resembles the agariciids Pavona venosa and Gardineroseris planulata.
