Coralla of this species form a very dense thicket composed of elongate, profusely budding corallites, secured and bound together by scalariform processes. Corallites are 3 to 4 mm in diameter and are nearly cylindrical. Septa are short, non-exsert, and do not extend all the way to the columella. The exterior of the corallites is covered by fine granulations, which often form slightly raised costal ridges.
Although previously recorded only from the Indian Ocean and Japan, Squires (1960) has described the species from shallow waters off Norfolk Island. The occurrence of the species in deep water in Cook Strait is of great interest. It is apparently not uncommon there, for at least two occurrences are noted. But perhaps more significant is the great number of corallum fragments which are brought up in the dredge. The great bulk of the coral is dead, but this is the usual instance in colonial forms of this sort.
