Notes: Previously placed under genus Pseudoceratina. Multicolor and multishape sponge, probably meaning there may be several species. The most usual morphotypes consist of a basal mass (could be ridged) with oscular lobes or long tubes, with bluish, purplish or pinkish tones; the surface is knobbed, often in a regular pattern. There is a distinct spherical yellow morphotype with collared oscules flush to the surface, which here is described as a separate form.
