Currently, the genus is considered as monotypic, consisting of a single species Pseudospongosorites suberitoides.

[5] Pseudospongosorites suberitoides was originally thought to represent a species in the genus Suberites, due to its superficial resemblance and similar ecology.

[2] Genetic work in 2002 led to its current classification as the sole member of a new genus under family Suberitidae and order Hadromerida.

It is polymorphic, typically appearing as green, brown, or tan, but approximately 10% of specimens are bright orange.

[5] P. suberitoides is mostly found in the Caribbean Sea and the Gulf of Mexico, though a few specimens have been collected from the North Carolina coast.

[6] They may occur in greatest abundance on the shores of the Apalachee Bay, along the Gulf Coast in northwestern Florida.
