Mesostigmatophyceae

The Mesostigmatophyceae are a class of basal green algae found in freshwater[1][2][3] containing two species in a single genus.[4]

Mesostigmatophyceae
Scientific classification
Domain:
Eukaryota
(unranked):
Archaeplastida
Kingdom:
Viridiplantae
Division:
Mesostigmatophyta
Class:
Mesostigmatophyceae

Marin & Melkonian, 1999
Order:
Mesostigmatales Cavalier-Smith 1998
Family:
Mesostigmataceae Moestrup & Throndsen 1988
Genus:
Mesostigma Lauterborn 1894 emend. McCourt 2005
Type species
Mesostigma viride Lauterborn
Species
  • M. grande Korshikov 1938
  • M. viride Lauterborn 1894

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.[5][6][7] Studies since the 2000s agree that Mesostigma, Chlorokybus and Spirotaenia form a clade, being the earliest diverging green algae.[8][9][10][11][12] Mesostigma are the only known streptophytes possessing flagella in their vegetative state.[13]
