diameter) and burr-like with 13–15 round-tipped, club-shaped rays in optical transverse section. In life, the colony is pale blue and white. In preservative, dark brown zooids (with brown cells in the haemocoel) can be seen through the common cloacal apertures and through the transparent spicule-free test around the branchial aperture. Clumps of zooids are in the test ligaments crossing the large common cloacal cavity from the surface to the basal test. These subdivide at the surface, separating thoraces from one another. Abdomina are partially or completely embedded in the basal test or are enclosed in the basal part of the test connective. These connecting pillars of test either are rigid with crowded spicules (SAM E3260), or the abdomina, seen through a single layer of spicules around the outside of the test connective, appear to be encased by a capsule of spicules.
