Characters: Colonies are thin, often overlapping laminae, with lobed margins. Corallites are irregularly distributed with deep seated columellae and thick, granulated septo-costae.
Colour: Green, brown or red-brown, with white perimeters.
Habitat: Usually found encrusting vertical or overhung faces.
Taxonomic Note: Placed in genus Cycloseris by Benzoni, Arrigoni, Stefani et al. (2012) based mainly on genetic evidence. It is retained here as a Coscinaraea 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 Psammocora explanulata, see 'Overview of coral taxonomy'.
