Skeletal Characters
| Oscules | small, scattered densely on both surfaces, <1 mm (d). |
| Texture | soft, compressible, resilient, not fragile, but easily torn. |
| Surface_Ornamentation | very smooth, with slight feeling of emory, gritty. |
| Ectosomal_Skeleton | penetrated by brushes of choanosomal oxeas and microxeas; many microxeas incorporated at surface. |
| Choanosomal_Skeleton | confused isodictyal reticulation in deeper choanosome; ascending unispicular tracts, tend to paucispicular tracts nearer to surface; microxeas abundant at internodes of oxeas in upper parts of tracts; little spongin at nodes; some foreign spicules incorporated irregularly. |
| Megascleres | oxeas: 3 classes class 1: stout, slightly curved, with sharply tapering points, in deeper choanosome, 120–150 × 6–8 μm; class 2: slender, slightly curved, with sharply tapering points, in tracts, ~130 × 4 μm; class 3: microxeas, fine, present at surface, 35–40 × 2 μm. |
| Microscleres | nil. |
