Maturity: Lm ?  range ? - ? cm
Massive. Well-developed oval or rounded oscula terminating short fistular processes on the upper surface. Smooth surface, harsh texture. Color: dirty-yellow when dry. Internal skeleton: approximately rectangular mesh; fibres usually stronger longitudinally than transverse; loosely cored with irregularly arranged strand of spicules. Spicules few on the transverse fibres. Dermal skeleton: darker, forming a polygonal network; meshes broken up by finer, irregular fibers in lighter color; spicules never polyserial, but is more numerous in the secondary fibres.
