The cell is free, large, and irregular with a central inflated region from where branches extend in all directions. A test has never been observed. On the seabed, the presence of T. alba is indicated by a distinctive, slightly raised, approximately circular mound of 18–40 mm diameter through which there are many perforations. Reticulopodia are occasionally seen at the base of the perforations.
