Portrait of Pediastrum duplex (Meyen, 1829 )demonstrating tufts of bristles protruding from the notch at the ends of the horns of peripheral cells (seen most clearly at one o'clock and 7 o'clock here). These bristles are thought to consist of proteinaceous microfilaments (see Scnepf,E. et al. J. Ultrastruct. Res. 72:367-379,1980). These nonmotile bristles may play a role in orienting the coenobia in the water column . DIC.

Kirchneriella (keyrsh-ner-ell-a) in which cells occur individually (particularly in cultures) or in colonies 4-16, rarely more. Cells live within gelatinous sheaths. Cells oval or oblong cylindrically, curved or screw-shaped curved. Both ends of the cells are rounded. A single chloroplast covers the inside of the cell and contains a single pyrenoid. The nucleus is located centrally near the concavity of the cell. Common in plankton of fresh water in lakes, ponds and rivers. This slightly squashed colony of Kirchneriella obesa was collected in the plankton from Lake Constance, Germany; cells measure 8 - 14 microns long. With an U-shaped incision. Differential interference contrast.
