Audouinella, also known as black algae, [1] is a widespread genus of red algae, found in marine and freshwater environments. [ 2 ] The form known as " black brush algae " (or " black beard algae ", BBA for short) is a particular nuisance in aquaria , since most algae eater fish and invertebrates avoid it.
The algae's black color is unusual for marine algae, [5] which are typically shades of green or red. [4] Several hypotheses have been put forth about the cause of this color. Terry Whitledge, director of the Institute of Marine Science at the University of Alaska Fairbanks , postulated that it could be due to the algae having undergone some ...
Black beard algae or black brush algae (referred to as BBA) belong to the genera Audouinella and Rhodochorton. It grows in the same habit as staghorn algae. [14] BBA, however, tends to grow in dense patches of fine strands. It may be a symptom of high levels of nitrates, phosphates, or iron. [15]

Cyanobacteria (blue-green algae) bloom on Lake Erie (United States) in 2009. These kinds of algae can cause harmful algal bloom. A harmful algal bloom (HAB), or excessive algae growth, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, water deoxygenation, mechanical damage to other organisms, or by other means.
Gloeocapsa magma gained notoriety in the Southeastern United States in the 1990s, but it has since spread throughout most of the rest of the United States and Canada. This particular type of cyanobacteria is responsible for creating black stains and streaks on roofs. [1]
