Conical, polyspicular tracts of triaenes and oxeas start with the narrow end in the choanosome, getting broader towards the surface. They protrude through the cortex and reach above the surface with the clads of the triaenes facing out. The cortex appears brown under the microscope and is a thin membrane, 15–40 µm in diameter with oxyasters distributed within the membrane. Spicules consist of dichotriaenes, straight rhabds, 4500–5600 x 180–230 µm, clads 380–525 x 180–225 µm per ray; long oxeas 8000–10,500
