[3] J.B. Bory de Saint-Vincent named the genus in 1823, in honour of his co-editor in the Dictionnaire Classique d'Histoire Naturelle, J.V.

[2] Audouinella reproduce via spores, most commonly asexually, while sexual reproduction is known in rare cases.

[2] Black algae are typically tolerant of high levels of pollution, acidity, and thrive on dissolved phosphate and nitrates.

[citation needed] It has been tested for germination and new growth using fertilizers NO3 and PO4, but results were negative from a decade of observations.

[citation needed] While other possible means of promoting growth may exist, the adjustment of CO2 concentration is the most consistent, as shown in practical tests by aquarists.
