Difflugia is one of several genera of Amoebozoa that produce shells or tests from granules of sand. These are swallowed by the cell and during the process of budding or fission they pass into the daughter, where they are joined by organic cement. The test has a single terminal opening. Difflugia are particularly common in marshes.
