Diagnosis
Massive, caliculate (Fig. 2A), short pedunculate, lamellar (Fig. 3A, C, Calyx arcuarius as Vagocia) or coalescent tubular growth forms, with tubular processes or fistulae may be present. Surface consists of a multilayered, compact ectosomal network, under the surface-membrane (Figs 2B, 3B), with a close-knit unispicular network containing spongin at nodes and scattered free spicules with numerous sphaerulous cells. These cells, brown pigmented or uncoloured, give to the sponge its dark or clear brown colour. Small oscules present in the internal part of the calyx (Fig. 2C), or absent. Choanosomal skeleton composed of long, disorientated, entangled spicular tracts, longitudinal in the interior of the body (Fig. 2D), and tangential to the surface in the periphery (Fig. 2B). Between the fibres there is a connecting unispicular reticulation (Figs 2D, 3D). Spongin in variable amount. Megascleres are oxeas, of two size categories, bent at the center, with conical points. Microscleres toxas (Fig. 3D, in Calyx arcuarius).
