Diagnosis

Encrusting, massive, digitate or bushy growth forms, often black colouration with a purple stained mucus; ectosomal skeleton thick, difficult to detach, composed of single spicules or poorly defined short tracts of spicules; choanosomal skeleton a regular reticulation of multispicular tracts; spongin maybe well developed and is usually darkly pigmented; megascleres are smooth choanosomal styles, or oxeas, or only strongyles inside fibres (all about the same size, without definite localisation of strongyles in the ectosomal skeleton); microscleres are birotulas. About 10–15 species, predominantly recorded from tropical waters, but at least one species is from the Arctic.
