Paraquadrula builds its scales from calcite, which is birefringent. This is the reason why in DIC (polarized light) they show such different magnitudes. Scale bar indicates 10 µm. Sample from a bog near Reith/Pillersee (Tyrol, Austria). The image was built up using several photomicrographic frames with manual stacking technique. Images were taken using Zeiss Universal with Olympus C7070 CCD camera.Image under Creative Commons License V 3.0 (CC BY-NC-SA).

The test of Netzelia tuberculata shows its mulberry surface which gave the name (tuberculata). As all Lesquereusiidae Netzelia builds up the test with self-made siliceous pads (called idiosomes). A few xenosomes (mostly parts of frustule from pennate diatoms) are also visible. All xenosomes are covered with a siliceous coating. Scale bar indicates 25µm Sample from a freshwater pond on the island of Hiddensee (Baltic Sea, Germany). This image was taken using Zeiss Universal with Olympus C7070 CCD camera.
