Oedogonium

Oedogonium Hirn: Oedogoniaceae. 

Green algae. Filamentous algae common in a wide range of water conditions, usually found growing attached to submersed plants or organic debris, as long strands or short fuzz. Some species create floating mats. The overall color ranges from dark green to yellow-green. Individual threads are made up of long cylindrical cells and do not branch. Under magnification, a ring or band is seen at one end of each cell, and rounded reproductive cells may be present. These algae are similar to Spirogyra, but the coarse strands making up the algal mass are tangled rather than parallel. Although the mucilaginous coating on the strands is apparent when they are rubbed, a mass of algae does not immediately feel slimy to the touch, nor slip from one's grasp. Can be abundant in stagnant, slow-moving water; hinders water flow in canals and ditches.
