Rhizamoeba
Rhizamonotactic form of Rhizamoeba spec.

 

Rhizamoeba spec.

This large Rhizamoeba had about 10-20 nuclei, each about 7 µm, with 1-3 peripheral nucleoli. It came up in a wet mount kept for some days in a moist chamber. In sediments from the Laegieskamp, 2014.

Stationary form, very sensitive to light, starts immedialtely retracting its pseudopodia when it comes into the light path.
