Characters: Colonies have nodular anastomosing branches or columns with encrusting or laminar bases. In turbid water colonies are predominantly laminar.
Colour: Pale or dark green, yellow, purple or brown.
Similar species: Porites cocosensis. See also P. lichen, which is best distinguished by its different growth-forms and larger corallites, although the size range overlaps. Corallites are closest to P. vaughani.
Habitat: May form single species stands on sloping reef faces in clear or turbid water.
