Diagnosis

Encrusting, massive or flabellate; ectosomal skeleton composed of smooth ectosomal tylotes with mucronate or spined ends, mostly standing erect, sometimes paratangentially, in bundles on the surface; choanosomal skeleton composed of smooth or slightly acanthose styles, sometimes oxeote or absent, forming an isotropic reticulation; fibres are poor but there may be abundant collagen; microscleres are birotulas, anchorate (unguiferous) isochelae and sigmas. About 10–11 species, occurring in northern and southern oceans, but so far not recorded in the tropics.
