Original Description

The genus Spongostaurus is readily identified by the characteristic lobular extensions of the central capsule. In the larger species each protrusion may attain a length of 19 mm with an average diameter of 2 mm. The capsular protrusions are surrounded by a thick gelatinous matrix (ca. 5 mm) supporting rhizopodia extending in a direction roughly normal to an imaginary tangent to the surface of the central capsule. The termina of the lobular projections are supplied with thickened rhizopodia extending through the gelatinous mass. A complex lobed nucleus is found in the central region of the capsule intercalating with the spongiose skeletal mass. The skeletal material is separated from the cytoplasmic material by a double membrane. The lobular projections are filled with oily droplets and contain most of the mitochondrial apparatus. The fusules (pores in the capsular wall) are typical for spongiose radiolaria (Anderson, 1976a), bearing a collar perforated with micropores. Spongostaurus gracilis is designated as the type species for the genus.

Editors' Notes
This genus, Spongostaurus Swanberg et al. 1984, was a junior homonym of Spongostaurus Haeckel 1882 so the replacement name Spongostaurina has been proposed
