Diagnosis: Cell dice shaped, surrounded by six hyaline, colorless, bowl-shaped scales, loosely attached to each other. Filopodia extend through gaps between the scales. Pseudopodia branching and when attached to the substrate also anastomosing. One vesicular nucleus.
Dimensions: My measurements cell body c. 4-10 µm.
Ecology: clear fresh water bodies, oligotrophic and mesotrophic water types.
Remarks: I have seen this variation or species several times, also together with the typical foreli form and the very small ones. According to Penard this should be young ones, but I´ve never see any transition or intermediate stages.
