Skeletal Characters
| Oscules | sieve plates present, variable in size, 1–5mm (d). |
| Texture | firm, barely compressible, resilient, friable, chalky, easily broken. |
| Surface_Ornamentation | gritty, sandpapery feel; ectosome easily rubbed away. |
| Ectosomal_Skeleton | not very well distinguished from choanosome; unspecialised; brushes of oxeas penetrate surface. |
| Choanosomal_Skeleton | isodictyal reticulation of oxeas, forming irregular meshes; spongin present at nodes; unispicular tracts ascend to ectosome. |
| Megascleres | oxeas: 3 classes class 1: stout, medium length, slightly curved, ends sharply pointed, very common, 130–150 × 6 μm; class 2: slender, strongylote, with one rounded end and other pointed, rarer than class 1 oxea, ~110 × 2 μm; class 3: small, stout, ends sharply pointed, 40–45 × 2 μm. |
