Characters: Colonies are encrusting laminae, sometimes with nodules at the colony centre. Corallites are small (4-6 mm diameter), mostly immersed and are slightly inclined towards the colony margins. Colour: Usually a uniform cream to dark brownish-green, but commonly brick red in Japan. Similar species: Unlike other Echinophyllia, but superficially resembles the faviid Echinopora lamellosa. It is readily distinguished by its exsert costae. Habitat: Most reef environments but especially turbid water on protected steeply sloping substrates. Abundance: Uncommon in Australia, common in the northern hemisphere.
