Diagnosis
Encrusting, massive, stipitate or branching sponges. Surface irregular to conulose. The ectosomal tylotes have variable terminations: mucronate, frequently with 1 or few prominent spines, or exceptionally entirely smooth, forming both a tangential skeleton and vertical spicule brushes; choanosomal spicules stylote, usually styles with or without spined bases, forming a tight meshed isotropic reticulation or looser isodictyal skeleton; echinating acanthostyles often present but sometimes lost; microscleres are anchorate spatulate or unguiferate isochelae with 3 teeth, often of several sizes, and sigmas (the latter sometimes lost). About 85 species.
