Diagnosis

Massive, lobate, globular, digitate and flabellate growth forms; with a single undifferentiated category of smooth auxiliary spicule (style, subtylostyle or modified style) forming plumose or plumo-reticulate choanosomal tracts, ectosomal brushes and also dispersed between skeletal tracts. Echinating acanthostyles usually heavily spined and distributed evenly over skeletal tracts. Microscleres include isochelae ranging from typical palmate form (straight shaft, lateral alae fused to shaft), modified palmate forms (thickened, curved shaft, partially detached lateral alae) to 'anchorate-like' forms (alae detached from shaft, shaft with lateral ridge); toxas if present include oxhorns.
