Plant' mass widely expanded, either forming a compact woolly layer 

 on moist earth, or a floccose mass floating in water, blackish or dull blue- 

 green; filaments long, flexible, (sometimes branched), strongly twisted and 

 densely crowded, or moderately flexuous or somewhat straight and loosely 

 entangled, sometimes forming erect fascicles in inundated places; sheaths 

 at first colorless, thin, smooth, later becoming thick, roughened on the 

 surface, lamellose, yellowish or brownish, with layers of different colors; 

 trichomes 8-24 mic. in diameter, not constricted at joints; apex of trichome 

 slightly tapering and capitate, truncate, rarely somewhat acute conical; 

 apical cell showing a slightly thickened outer membrane; cells 2.7-5.6 mic. 

 in length; cell contents finely granular, blue-green or olive.
