The Mesostigmatophyceae are a monotypic class of green algae[1] found within the division charophyta that contains two species.[2]

Earlier studies were unable to resolve the position of the species, and it was often placed as a sister to all other green algae, as one of the basal members of the Streptophyta, or as close to Chaetosphaeridium.[3][4][5] More recent studies agree that Mesostigma and Chlorokybus form a clade, being the earliest diverging charophytes.[6][7]
