Milne Edwards and Haime, 1851


Lamarck, 1801

Colour: Rust brown, usually with pale margins. Mouths are white and star-shaped, a useful identification aid.

Similar Species: Agaricia grahamae, which is usually distinguished by lack of white mouths, and septo-costae which do not alternate and are thicker than the spaces between them.

Abundance: Common.
