Corallites cylindrical and small, 4– 5.9 mm in diameter and 2.5–5 mm in height. Epithecal wall higher than septal margin. Septal order is hexameral and in four cycles, which may be incomplete. Septa have a lateral granulation. Columella well-developed and granulated. Fossa shallow. Living corallites are light pink. Type locality Mie Prefecture , Japan , depth 100 m . Distribution Korea ( 20 m ) ( Song 1991 ), Japan ( Ogawa et al. 1996 ), open water seabed and Conic Island and Steep Island Caves, Hong Kong ( Lam 2003 ; this study).

Collinson (1997) also reported recruitment of this coral onto plastic plates in the same bay.
