Diagnosis
Massive, pedunculate or flabellate sponges with plumoreticulate choanosomal skeleton, composed of anastomosing columns of large subtylostyles (mycalostyles), condensed in the interior and thinning out towards the surface. In species with desmas, these are concentrated in the interior forming an axial column (Hooper & Lévi 1989). Microscleres include up to three categories of palmate isochelae, which may occur in rosettes, and up to two categories of sigmas. About 50 species have been recorded but these need revision. Most occur in higher latitudes or in deeper water.
