Larva can be found in pools with stagnant waters containing "Spirogyra". Several species have been noted to feed on algae such as "Spirogyra". Freshwater filtration applications commonly involve species such as "Spirogyra". Aquatic vegetation has species of "Chara", "Spirogyra", "Hydrilla", "Potamogeton" and "Vallisneria". Mats formed by "Oedogonium" are multi-species, associated with "Spirogyra", "Rhizoclonium", and "Cladophora". Members of the Zygnemataceae, such as "Spirogyra", fall prey to parasites, especially chytrids. At the Octagon, Howard often played support for the folk/progressive rock band Spirogyra. The flora contained in the lake mostly amounts to Spirogyra and Curly-leaf Pondweed. Unlike "Spirogyra" the filaments of "Cladophora" branch and do not undergo conjugation. If, Spirogyra, Atomic Rooster, Alexis Korner, Gryphon and Steamhammer. This process is called "conjugation" and occurs for example in "Spirogyra". This occurs in some the green algae, the Zygnematophyceae, e.g., "Spirogyra". "Spirogyra" can reproduce both sexually and asexually. Spirogyra has a cell wall, nucleus, pyrenoid and spiral chloroplasts. "Spirogyra" is very common in relatively clear eutrophic water, developing slimy filamentous green masses.
