A large rounded sponge up to 15 cm in diameter and height up to 10 cm. The consistency is firm-hard, but slightly compressible. The smooth surface is bluish or violet-grey and extensively perforated with inhalant orifices. Larger exhalant openings (osculum) are distinct and usually in lines or arranged in clusters. The skin (cortex) is distinct and 1 mm thick, underneath the surface the colour is yellow-white.

Description
This sponge may be massive-lobose, hemispherical to irregularly rounded and up to 30cm or more across. It is usually grey to off-white in colour but may be completely white in dark caves. Rounded evenly spaced oscules are obvious all along the tops of the ridges. Unlikely to be confused with other species.

Pachymatisma johnstonia grows on bedrock and hard substrata in the intertidal and subtidal to 300 m depth. It is often found projecting into water currents off cliff walls. Found on overhangs in extremely sheltered waters but more common in areas with strong water movement.

Pachymatisma johnstonia
Pachymatisma johnstonia is a species of demosponge belonging to the family Geodiidae. A species of north east Atlantic coasts, this is a usually grey encrusting sponge with large prominent oscula and a pale yellow interior. The size and form depends largely on the extent of its exposure to waves. In heavily wave-exposed locations, it is usually small and thin but in more sheltered places can grow to over 50 cm across and 15 cm thick.
