SYNOPSIS. Colonies of Prymnesium parvum from single cells were obtained in an atmosphere of high humidity, in soft‐agar overlayers on solid medium. Light intensity above 60 foot candles at the surface of the agar plates inhibited colonial development. Such colonies were used to obtain pure lines of the phytoflagellate. A method for direct demonstration of hemolysin formation on agar plates was developed. The occurrence of hemolytic activity by P. parvum colonies was light‐dependent.
