Raphidocelis subcapitata, formerly known as Selenastrum capricornutum and Pseudokirchneriella subcapitata is a microalga. This microalga presents a curved and twisted appearance like a sickle. The cells are normally presented in a solitary form. It has a length between 8 and 14 μm, and a width between 2 and 3 μm. It is commonly used as a bioindicator species to assess the levels of nutrients or toxic substances in freshwater environments. This species is quite sensitive to the presence of toxic substances including metals and has a ubiquitous distribution, so is broadly used in ecotoxicology. This species has been found to be more competitive than Chara vulgaris at low sodium chloride concentrations, but C. vulgaris was more competitive under salt stress.

| - Raphidocelis subcapitata, anciennement dénommée Selenastrum capricornutum ou Pseudokirchneriella subcapitata, est une espèce de microalgues de la famille des Selenastraceae. Les cellules, généralement solitaires, ont une forme de croissant évoquant une faucille. Elles mesurent de 8 à 14 µm de long et de 2 à 3 µm de large. Cette espèce est communément utilisée comme bioindicateur pour évaluer les niveaux de nutriments ou de substances toxiques en eau douce. Elle est en effet sensible à la présence de substances toxiques dont les métaux et est omniprésente d'où son utilisation en écotoxicologie. Elle est plus performante que Chara vulgaris aux faibles concentrations de chlorure de sodium, mais cette dernière lui est préférée en cas de stress salin. (fr)
