Characters: Colonies are dome-shaped clumps of interlocking branches up to 2 metres across. Branches are formed of single tubular corallites (or axial corallites) with lateral buds. Corallites are 5-8 millimetres diameter. Costal spines are widely spaced and not exsert. There is little tendency to form laminae or solid bases. Colour: Pinkish-brown with pale corallite ends. Similar species: Corallites are similar to those of Echinopora gemmacea. The growth-form is more like that of E. horrida, which has corallites with exsert costal and coenosteum spines. Habitat: Most shallow reef environments. Abundance: Common.
