Characters: Colonies are usually unifacial plates with laminar margins and encrusting centres. Corallites are up to 10 millimetres diameter. Septo-costae are in two orders, the second seldom forming well developed septa. Septal teeth are exsert. Costae are beaded. Paliform lobes are not exsert. The coenosteum has tall spinules giving colonies a velvet-like appearance. Colour: Green, yellowish or grey-brown. Similar species: Echinopora lamellosa, which has similar but smaller corallites and forms larger colonies with more development of plates. Habitat: Most shallow reef environments. Abundance: Usually uncommon
