Capsellina bryorum amoeba

Capsellina bryorum, an amoeba found in lake moss, was discovered by Swiss biologist Eugene Pernard in 1909. It can also be found in freshwater sphagnum.  Capsellina bryorum is composed of organic materials and collected debris.  Its shell usually has a single opening. This slit-like invagination shows on the surface and goes down into the cell.  It can be open or closed and is very distinct, but not always clearly visible.  The cell is surrounded by a membrane which is covered with minute xenosomes. The plasmabody fills the membrane completely. It has a single vesicular nucleus.

There has been little research on this amoeba since its discovery at the beginning of the twentieth century.
