Colonies are hemispherical. Corallites are conical and uniform in shape. They show both extra- and intratentacular budding. Paliform lobes form a neat crown. Septa are fine and neatly arranged. Costae are also neat; a tiny line of demarcation, visible underwater, separates costae of adjacent corallites.
Uniform, usually pale brown or pinkish-brown.
Shallow reef environments.
Common in the Red Sea, uncommon elsewhere.
