Lithocolla flavescens
Lithocolla flavescens

Lithocolla flavescens Penard, 1904

Diagnosis: amoeba surrounded by a thin layer of small irregular mineral grains, fixed on a thin flexible membrane; numerous fine smooth filopodia, without any granules which are so typical for true heliozoans; plasmbody usually with a yellowish color. Nucleus vesicular with central nucleolus. Fast movement.

Dimensionsc. 10 µm.

Ecology: I have sampled this species in the marshes of Kortenhoef and in a small river in Neer, in the southern part of the Netherlands.

Remarks: this amoeba can move fast, but doesn’t have a rolling movement like true heliozoans.  The taxonomic status of this species is uncertain.
