Description

The specimens presented various morphotypes ranging from branching erect with distinct branches/ projections to fuse branches, i.e., lamellated morphology. When preserved in ethanol, the colour is pale yellow. Given that the specimens were not observed in situ, the natural colour is unknown. However, the specimens of this species have been reported with a live colour ranging from white-grey to pale yellow. The surface is uneven rugose, varying in different specimens from almost conulose to smooth.

Skeleton

The skeleton is composed by a thick mesh of strongyles and oxeas, and with styles protruding the surface. Megascleres are: flexuous strongyles and oxeas measuring 570–1200 µm× 14–20 µm (N=4), and styles measuring 975–1175 ×10–15 µm (N= 4).
