Characters: Colonies are branching. Corallites are widely separated, sometimes angular in outline, with a solid conical columella. Usually ten septa are present and these are fused with the columella. The coenosteum has fine spinules which sometimes form a ridge between corallites. Tentacles are extended day and night.
Colour: Light yellow, cream or pale brown.
Similar Species: Madracis decactis.
