Colour: White when dry.

Surface smooth, but foreign objects may be found incorporated on the surface. Oscules and pores are not traceable. The skeleton of the dermal part is composed of dichotriaenes with their shafts pointing inwards
and oxeas arranged tangentially over the clads of dichotriaenes. Smaller oxeas are generally scattered irregularly. Large oxeas seen just below or intermingled with the layer of smaller oxeas arranged irregularly or in bands of 2-3. Clads of younger dichotriaenes are seen just beneath those of the well developed dichotriaenes.The main skeleton is poorly developed and is composed of bands of large oxeas arising from the substratum in a slanting manner. These bands, after meeting the dermal skeleton, run in parallel courses, reinforcing the dermal skeleton. Spicules:Dichotriaenes. Shaft short and pointed. Protoclad usually longer than deuteroclad in younger forms; large oxeas biangulated or not, rarely stylote; small oxeas. Dermal, slightly curved and with or without a swelling in the central part.
Stylote or strongylote spicules noted.
