Colonies are submassive or have laminar bases and form tall columns and branches. Laminar and digitate forms are usually found in turbid water, submassive and columnar forms occur on reef slopes. Corallites are mostly exsert. The coenosteum has a dense cover of papillae of uniform length.
Brownish, usually with white tips to coenosteum papillae, especially on distal parts of branches.
Sheltered environments, especially sheltered lagoons with turbid water and soft substrates.
