Characters: Colonies have encrusting bases on which cylindrical columns are developed that may reach 2 metres in height. Valleys are meandroid. Septo-costae are thick, in two alternating orders; they do not join at the tops of valleys and thus leave a neat groove along the tops of walls. Tentacles remain extended during the day giving columns a furry appearance.
Similar Species: Superficially resembles Scapophyllia cylindrica.
