“From Veron, J.E.N. Corals of the World.”
Characters: Colonies are encrusting, laminar or columnar, the tops of columns commonly having vertical or flame-shaped ridges. Encrusting colonies may have rootlets. Corallites are immersed, without papillae and are aligned vertically between ridges on columns. The coenosteum is coarse; this can be seen underwater.
Colour: Usually mottled or uniform brown, cream or blue, sometimes with distinctly coloured margins.
