The general appearance of the colony is bushy, but there is a distinct difference between the basal part of the stems, where the perisarc is quite thick, and their distal parts, where it is much less developed. In some gonothecae the most distal ring is not completely formed, giving rise to a sort of step before the funnel (fig. 6d), which makes the funnel apparently higher than in most gonothecae (fig. 5f–g).

the rings are independent, not forming the spiral pattern present in some species, and do not form the outward extension or frill that typically characterises others. Furthermore, the relatively large, conspicuous distal neck bearing the gonothecal aperture may be characterised as relatively low and wide, shorter and wider than in other species of the genus. Finally, the rings are characterised by having a conspicuous trabecular structure (fig. 5h).
