Chlorangiella is a genus of microscopic algae, the type genus of the family Chlorangiellaceae.[1] The name Chlorangiella was coined by Giovanni Battista de Toni in 1889.[1] It is a nomen novum for Chlorangium F.Stein.[1]

Species of Chlorangiella are attached via stalks to freshwater algae, crustaceans, rotifers, or insect larvae.[2] They can attach to the substrate, such as the copepod Cyclops, in such large quantities as to make them appear green.[3] They have been recorded from many continents, mostly in temperate habitats.[1]

Description

Chlorangiella consists of single cells or groups of cells, where the cells are borne on the ends of mucilaginous stalks. Stalks may be branched or unbranched and up to 5 times the lengths of the cells. The cells themselves are ovoid, 5–42 μm long. They contain a single cell nucleus (i.e. are uninucleate) and contractile vacuoles at their apices. Chloroplasts are one to several, parietal and band-shaped, with or without a pyrenoid.[1]

Asexual reproduction occurs by the formation of zoospores. The zoospores may be released at the apex of the sporangium, and swim until they settle and develop into a new organism; alternatively, they may attach at the base of the sporangium and develop a stalk. Sexual reproduction has not been observed in this genus.[1]
