Ischyrospongia

Longitudinal section of Claracrusta ungdarelloidea, from Vachard et al. (2001).

Belongs within: Diaphoretickes.

The Ischyrospongia were originally recognised as a grouping of hypercalcified sponges including the sclerosponges and stromatoporoids. Some subsequent authors have also placed a number of Palaeozoic microfossils of uncertain affinities within this taxon. These include the Moravamminida in which the test is divided by septa or pseudosepta and has a calcareous, hyaline wall.
