Lyngbya (Microseria wollei, formally Lyngbya wollei) is a genera of filamentous cyanobacteria that includes both freshwater and marine species. Lyngbya found in Lake Gaston can be identified by dense, dark-colored mat formations, wool-like texture, and musty odor. Unlike other algae, lyngbya persists year-round along the lake bottom, but as water temperatures rise, it begins to proliferate upwards through the water column, forming floating mats at the water’s surface. Lyngbya has become increasingly problematic in reservoirs throughout the southeastern US and is associated with a host of negative ecological and human-use impacts.
