Cochliopodium spec.

Diagnosis: Cell in locomotion rounded to oval, no subpseudopodia observed, only a broad anterior margin of hyaloplasm. Nucleus vesicular with central granular nucleolus. Micro scales relatively large; in phase contrast they show  a funnel-shaped  apical part connected to a base plate by a column of at least two stalks, converging towards the top.

Dimensions: Length in locomotion up to 50 µm (n=7); nucleus c. 6-6.8 µm; height of micro scales c. 2.3-2.5 µm, top of the scales 1.2-1.5 µm width, column about 0.4-0.6 µm in diameter; base plate c. 1.7-2.0 in diameter.

Ecology: Freshwater, peat bog, Diepveen.

Remarks: This species is remarkable by its relatively large micro scales, which are easy visible light microscopically in phase contrast.

In an old sample all specimens of this Cochliopodium sp. looked like this one, spherical.

Specimen in the biofilm of the Haaksbergerveen, an old peat area in the Netherlands. Maybe the same species as the one described above.
