Sponge forming massive, reticulate colonies of asconoid tubes, closely resembling Clathrina ceylonensis but somewhat coarser.

The regular triradiates have rather stout, slightly fusiform rays, bluntly and rather abruptly pointed at the apex, which is often somewhat irregular.

The quadriradiates are abundant and resemble the triradiates, but with an apical ray projecting at right angles into the gastral cavity.

This ray is somewhat variable in form and size; typically it is long and slender, gradually and sharply pointed, and slightly undulated towards the extremity; in the type specimen it attains a length of about 0.14 mm.

They taper very gradually from the proximal extremity, which is somewhat hastately sharp-pointed and may be as much as 0.004 mm thick, to the distal, which is hair-like and apparently nearly always broken off.
