Quick Summary

Cladophora glomerata is a genus of green algae found attached to submerged rocks and timbers in shallow lakes and streams. These algae are characterized by their coarse appearance with regularly branching filaments. They reproduce both asexually through motile spores and sexually through gametes.1

While some algal blooms are natural and beneficial, Cladophora species are often considered a nuisance, particularly in recreational waters. In areas like the Great Lakes, their overgrowth has been linked to the proliferation of invasive zebra mussels. Green algae, in general, are diverse, ranging from single-celled to filamentous forms, and play a crucial role at the base of aquatic food chains.12
