Diagnosis
The body is tubular with numerous lateral oscula and withcolander-like sieve-plate. The sponge lophophythose attached to the substratum with anchor-like basalia. The principal choanosomal spicules (large) are chiefly stauractines usually together with hexactines or pentactines. The distal rays of such hexactines and pentactines are rough, the proximal ones in hexactines are always rudimentary. Additional choanosomal spicules are diactines, tauactines and rarely stauractines together with more rarely found other derivatives. The choanosomal spicules form longitudinal and circular skeleton beams. The sieve-plate contains hexactine derivatives various in different species. Basalia are anchor-like spicules with 4 and more teeth. Dermalia are hexactines. Atrialia are pentactines. Microscleres are floricomes and graphiocomes, sometimes hexasters and small sigmatocomes, rarely discohexasters, hemihexasters, hexactines and onychasters.
