描述：Cells are solitary and pyramidal or tetragonal. Walls are ornamented by regularly arranged rows of depressions, in contrast to Pseudostaurastrum, which has similar cells shapes but does not have the regular ornamentation found in Tetraedriella. Several to many parietal plastids are present. Reproduction occurs by autospores and zoospores. Tetraedriella is metaphytic in dystrophic, mesotrophic, and eutrophic lakes, ponds pools, and seeps in Minnesota, Alaska, and Arkansas, Montana, and Kentucky.
