Skeleton:
Ectosome, a tangential layer, 60 -80 μm thick, with Oxeas and Toxas. Ectosomal membrane supported by spicule bundles.
Choanosome with multispicular tracts running toward surface. Single spicules united isodictially, or in confusion between tracts.
Distribution: Central, Southern California.
Depth: Subtidal to 18 m.
Note: This species was originally designated as Toxadocia zumi. This species appears quite different from Toxadocia now placed in Haliclona (Reniera) by de Weerdt, 2002. Recent review places it in Xestospongia.
