Diagnosis

Thickly encrusting, massive, globular, digitate, flabellate and arborescent growth forms; with specialised ectosomal skeleton of differentiated size classes of auxiliary (subtylo)styles, with smaller ectosomal spicules usually overlaying larger subectosomal ones forming erect brushes in a continuous palisade, or discrete bundles, paratangential or rarely tangential to surface. Choanosomal skeleton without any marked differentiation between axial and extraaxial regions. Echinating acanthostyles usually present. Microscleres are palmate isochelae and diverse forms of toxas.
