Morphology<\/h2>\n

Trichomes rarely solitary; usually in smooth macroscopic mats. Trichomes straight to slightly waved, sometimes slightly coiled near the ends; cylindrical and isopolar; mostly >6.8 \u03bcm wide, and up to 70 \u03bcm wide; constricted or unconstricted at crosswalls. Trichomes typically without sheaths; sheaths only occasionally present in response to environmental stress. Trichomes are motile, with gliding or oscillating movement. Cells short, discoid (coin-like shape); cell length is always less then one-half the cell width, and cells are usually 3-11 times shorter than they are wide. Cell content homogeneous or with large granules; without aerotopes. Apical cells may be rounded, capitate, bluntly pointed, elongated, bent; with or without calyptra; with or without a thickened outer wall. Trichomes disintegrate into hormogonia, with formation of necridia.<\/p>\n

Ecology<\/h2>\n

Mainly benthic, forming mats on various substrata in shallow waters, swamps, and marshes. Common species are found in lakes, ponds, pools, and slow-flowing rivers, growing among algae or on muddy and sandy subtrates.<\/p>\n
