Diagnosis

Branched, tubuliform or vase-like growth form, with tendency to form coalescent tubes or masses of branches, with a common base, with large apical vents, or irregularly distributed oscula. Surface strongly to finely conulose or spiny. Texture elastic, strong or fragile and breakable, in dry state. Ectosomal skeleton network, strictly tangential, primary secondary and tertiary fibres in one plane, determining three sizes of irregular mesh (Fig. 4A). Several end branches of one primary longitudinal fibre form the skeletal axis of each surface conule or spine (Fig. 4B). Choanosomal skeleton strong, irregular, with primary longitudinal fasciculated fibres, abundantly ramified to form free secondary and tertiary fibres with rounded to elongate, always subdivided mesh (Fig. 4C, D). Spongin always visible present in variable amounts. Spicules: oxeas to strongyloxeas well developed or vestigial.
