There is a clearly defined test wall, about 220 to 245 µm thick, composed mainly of short, sponge spicule fragments and tiny transparent mineral grains (~10–50 µm in size), as well as occasional radiolarian shells. A few agglutinated foraminiferal shells are also incorporated. The spicules form a three-dimensional mesh that creates a very distinctive, somewhat labyrinthic appearance. There are few if any internal xenophyae and the test interior is largely occupied by dense stercomare. Narrow, pale cream granellare strands are exposed on the broken end of the fragment (
