Spirogyra (common names include water silk, mermaid's tresses, and blanket weed) is a genus of filamentous charophyte green algae of the order Zygnematales, named for the helical or spiral arrangement of the chloroplasts that is characteristic of the genus. Spirogyra species, of which there are more than 500, are commonly found in freshwater ...
Spirogyra at Kent University, 1971. Their debut album, St Radigunds, was recorded at Sound Techniques studio, produced by Robert Kirby and engineered by Jerry Boys. Named after the Canterbury street on which the members lived, its lyrics express the anti-capitalistic, anti-materialistic orientation of the band and of the broader Canterbury scene.
The Zygnemataceae are cosmopolitan, but though all generally occur in the same types of habitats, Mougeotia, Spirogyra, and Zygnema are by far the most common; in one study across North America, [3] 95% of the Zygnemataceae collected were in these three genera. Classification and identification is primarily by the morphology of the conjugation ...
Members of the Zygnematophyceae are common in nearly all freshwater habitats, particularly filamentous genera such as Spirogyra and Mougeotia. Some Spirogyra species can tolerate disturbed habitats. On the other hand, desmids (the Desmidiales) often prefer bogs, peatlands, and lakes. [17]
The larger family Zygnemataceae, with well-known genera such as Zygnema and Spirogyra, includes members that grow as unbranched filaments, which grow longer through normal cell division. This group includes the desmids.

In 1974, when a bar owner asked for the band's name, Beckenstein said, "spirogyra", a type of algae he had learned about in school. [1] The bar owner wrote the name incorrectly, "Spyro Gyra", but it stuck. [1] The founding members of the band were Beckenstein, Wall, bassist Jim Kurzdorfer, drummer Tom Walsh, and keyboardist Tom Schuman. [1]
