Colonies are small (less than 50 mm across), partly encrusting and have one or several conspicuous central corallites. Peripheral corallites are small or may be absent. Peripheral corallites are inclined towards the colony margins and are distributed irregularly. They have small openings. Septo-costae are granulated and strongly alternate. These radiate from the central corallites giving the colony a striped appearance.
Brown or yellowish with white margins and white tops to costae.
