Pompholyxophrys punicea

Pompholyxophrys punicea Archer, 1869

Diagnosis: Cell spherical, coated with two or three layers of spherical siliceous perles. Dried perles with a regular smooth outline. Filopodia fine and short, emerging through the layer of perles. Cytoplasm usually reddish, oft with large foodvacuoles. Nucleus spherical with central nucleolus. Fast rolling movement.

Dimensions: Cell with periplast 24-65 µm; perles 1.0-7.5 µm.

Ecology: Fresh water, common in clear water and wet Sphagnum, specially in summertime; recorded from Europe. North and South-America, Malaysia. I have found this species at several locations in the Netherlands, Denmark and Sweden, usually in clear water with Sphagnum contact.

Literature: Siemensma (1991), Rainer (1968).
