Pisidium hibernicum is a species of freshwater bivalve from the family Sphaeriidae.
The 2.5-3.5mm. shell is very inflated (convex) hence the common name Globular Pea Shell. The central umbos is prominent. The periostracum (surface) is silky glossy and sculptured by fine, regular striae. In colour it is greyish to brownish white often with scattered red-brown mineral deposits.
