Clathrina laminoclathrata is a species of calcareous sponge from Australia.

It is possible that this basal lamina is only an artefact created by the dried state of the specimen as Dendy (1891) supposed, but the skeleton in this region of the sponge is different from the skeleton in the tubes.

The skeleton is formed by triactines only, as stated by Carter (1886) in the original description, although there are in fact three different categories of triactines, based on size.

The largest are generally found on the external tubes of the sponge, i.e. on the surface of the cormus.

There is no specialization of the tubes and the organization of the cormus is typical of Clathrina.
