Characters: Colonies are massive or are thick plates. Corallites are up to 8 millimetres diameter, closely compacted, and thick walled. Septo-costae are in two alternating cycles, those of the first cycle being very exsert and coarsely beaded. Columellae are large and consist primarily of fused paliform lobes. Colour: Grey- or greenish-brown. Similar species: Echinopora forskaliana. See also E. hirsutissima, which has relatively widely spaced corallites, less conspicuous first cycle septo-costae and smaller columellae. Colonies with closely compacted corallites are Favia-like. Habitat: Shallow reef environments. Abundance: Rare
