Skeletal Characters
| Oscules | many of which have small oscules on the apex or lateral sides of bulbs |
| Texture | firm, harsh, barely compressible |
| Surface_Ornamentation | surface lumpy with low bulbs |
| Ectosomal_Skeleton | ectosomal skeleton consists of a thick crust of oxyspheraster euasters with a large centrum (these appear to differ from spherasters of Geodia) |
| Choanosomal_Skeleton | choanosome with irregular tracts of long robust oxeas in more-or-less disorganised halichondroid skeleton; mesohyl moderately heavy with rare orthotriaenes (ie only one seen in the sections) |
| Megascleres | shorter thin oxeas, sometimes curved otherwise straight |
| Microscleres | abundant toxa-like rhabds that have a central bend and have either straight or slightly reflexed arms, occuring singly or in trichodragmata bundles, and scattered oxyspheraster euasters with large centrums and rarer oxyaster euasters without a centrum. |
