Paraquadrula irregularis

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 Axioplan with Canon 600D CCD camera.
