External characters
repent, multiple flattened lobate projections arising from a spreading base; dimensions: ~12 cm (l), ~6 cm (w), ~8 cm (h).
Colour
pink-purple (yR 5/2) in life; dark brown (yY-R 3/2) in ethanol.
Skeletal Characters
| Oscules | large, ~3–6 mm (d), flush with surface, scattered. |
| Texture | soft, flexible, easily torn. |
| Surface_Ornamentation | low, irregularly distributed conules; conules ~1–1.5 mm (h), rounded or pointed tips, connected by sandy tracts running in plane of surface in some areas but not over whole surface; tracts white; irregular web-like appearance. |
| Ectosomal_Skeleton | ~200–300 µm (depth); exhalant canal lacunae; dense superficial region of light collagen reinforcement, ~30–40 µm (depth). |
| Choanosomal_Skeleton | fibrous; all fibres cored; impossible to distinguish primary and secondary fibres by size or orientation except in immediate subsurface area; fibres large, ~120–400 µm (d), heavily cored, strongly stratified, form irregular network; negligible collagen, low mesohyl content, most volume occupied by choanocyte chambers and canals; chambers oval, eurypylous, ~50–80 µm (max. dimension); all areas contain numerous dark brown pigmented cells; interstitial debris absent. |
| Megascleres | nil. |
| Microscleres | nil. |
