Rhizoclonium

Rhizoclonium Kuetzing: Crinkle grass. Cladophoraceae 

Green algae. These are thread-like, mat-forming algae; they do not attach to a substrate. The slender filaments have almost no branching but may produce short lateral projections called rhizoids. Cells are 2 to 4 times longer than wide, seen under magnification. These algae form large tangled coarse mats or skeins that float near the surface, held up by the oxygen they produce, or snagged by underwater objects. Mats hinder swimming and fishing. Generally found in shallow and hard water, Rhizoclonium grows in similar places as Cladophora, to which it is related. These algae are very problematic in irrigation and drainage canals where they may hinder flow.
