The Oedogoniales are an order of filamentous freshwater green algae of the class Chlorophyceae.[1] The order is well-defined and has several unique features, including asexual reproduction with zoospores that possess stephanokont flagella: numerous short flagella arranged in a subapical whorl.[1] The oedogoniales have a highly specialized type of oogamy, and an elaborate method of cell division which results in the accumulation of apical caps.
The order comprises one family, Oedogoniaceae, with three genera.[2] Some common features among these genera may be obscure. The hairs of Bulbochaete and the heterotrichous system Oedocladium are similar to Chaetophorales, with which they may share a distant relationship.[3] Of the genus Oedogonium there are over 330 species, about 70 species of Bulbochaete, and 10 species of Oedocladium. More than half of these species are known to North America.[4] Many of the species are used by aquarium owners.[citation needed]
Members of the order usually inhabit still waters such as lakes and ponds, rather than rivers and streams.[1] The oedogoniales include free-living and epiphytic members on other algae or freshwater angiosperms.[1]
