SUMMARY The snow alga Trachelomonas kolii is transferred from the Euglenophyta (Euglenales) to the Chlorophyta (Volvocales) as Chlainomonas kolii comb. nov. As a result of critical examination of both living and type material, this species was found to have 4 flagella per vegetative cell, true starch, and 1 axial plastid per cell with several peripheral lobes. Vegetative cells of Trachelomonas kolii were described originally as having 1 flagellum, lacking true starch but having paramylum, and as having several parietal plastids per cell. The reticulate markings on the outer envelope of vegetative cells were found to be different from those in the original illustrations. Vegetative cells and resting spores of Chlainomonas kolii and Chlainomonas rubra are compared. The similarities of resting spores of Chlainomonas kolii and Chlamydomonas nivalis are discussed. These are the first records of Chlainomonas kolii from snow in Washington State.
