Colonies are submassive or laminar. Corallites are small; some exsert, some immersed. Corallites are separated by papillae or tuberculae of about one corallite diameter.
Usually dull brown or green, but may be bright blue (which may photograph pink or purple). Tips of papillae are often distinctively coloured.
Most reef environments.
