Limnofila spec.
cf. Mesofila spec., dividing – Laegieskamp

cf Mesofila spec.

Diagnosis: Cells roughly circular, numerous (up to 21) sometimes branching filopodia of varying lengths (1-5 times cell diameter) emerge from the cell body and extend along the substrate. Filopodia carry numerous granules, evenly spaced at intervals; no anastomosis. Cell and filopodia in contact with substrate. Cells immotile and solitary; no flagellate stage or cysts seen.

Dimensions: Cells about 10 µm in diameter.

Ecology: Bacterivorous. I found this species in moist chamber preparations from peat bog samples in The Netherlands. It seems a common species, but easily overlooked by its size. I could only detect them with a 40X or 100X phase contrast objective.

Cell with contractile vacuole.
