Conferva is a genus of freshwater green algae that typically forms a tangled mass of thin filaments. The spelling of conferva is pronounced /kənˈfɜːvə/ and is derived from the Latin word "confervare" which means to grow together. The IPA phonetic transcription of the word follows the standard English sound system with the first syllable pronounced with a schwa followed by a stressed 'f' sound. The second syllable is pronounced with an 'er' sound and the word is concluded with a weak schwa sound.
Conferva is a noun that refers to a type of aquatic filamentous green algae belonging to the class Chlorophyceae. These algae are typically found in freshwater environments, such as ponds, lakes, and slow-moving streams, although they can also be present in marine habitats. The term "conferva" is derived from the Latin word "confervere," which means "to boil together" or "to thicken." This term was initially used to describe any long, thread-like aquatic plant, but it is now commonly used specifically for filamentous green algae.
Conferva algae are characterized by their slender, unbranched thalli or filaments, which consist of a chain of cylindrical cells that are often coated with a slimy matrix. This slimy substance aids in their adhesion to rocks, plants, or other substrates in their aquatic environment. The filaments can vary in length and may grow as long as several centimeters. They possess chlorophyll for photosynthesis, enabling them to convert sunlight into energy.
Conferva algae play a vital role in aquatic ecosystems as they provide food and habitat for various aquatic organisms. They also help maintain water quality by oxygenating the water and absorbing excess nutrients. Additionally, they act as indicators of water pollution since their growth is promoted by nutrient-rich environments. Conferva is a common part of the aquatic flora, and its presence can be visually striking, forming a green carpet-like appearance in bodies of water.
In bot., fresh-water plants, consisting of slender-jointed green filaments.

The word "conferva" originates from Latin. It is derived from the combination of two Latin words: "con", meaning "together", and "fervere", meaning "to boil" or "to seethe". Therefore, "conferva" etymologically means "together boil" or "together seethe". In botanical terms, "conferva" refers to a type of filamentous green algae, commonly found in freshwater or marine environments.
