Calcifibrospongia actinostromarioides

Notes: Orange, hard, encrusting plate, with regularly scattered oscules. It is a sclerosponge, which means it has a basal skeleton of calcium carbonate (still to be confirmed) in which the sponge tissue is embedded. Spicules are strongyles to strongyloxeas in a loose reticulation. Ground and polished hystological sections of tissue with skeleton are needed for further confirmation.
