Diagnosis
Encrusting, lobate or pedunculate; ectosomal skeleton composed of a tangential layer of acanthoxeas or acanthostyles; choanosomal skeleton composed of smooth tornotes or strongyles arranged in tracts which may be echinated by acanthostyles, or in encrusting forms there may be an erect basal layer of acanthostyles; microscleres may include arcuate isochelae, sometimes absent, and occasionally sigmas. More than 50 species.
