abstract = {Although zygote morphology is important in traditional taxonomic systems of snow-inhabiting species of Chloromonas (Volvocales, Chlorophyceae), induction of sexual reproduction or hypnospore formation is difficult in culture. Thus, alternative taxonomic methodologies are required when sexual reproduction does not occur in cultures. Here, we performed a taxonomic study of snow-inhabiting Chloromonas species based on culture strains with elongate or ellipsoidal vegetative cells. Our comparative light and electron microscopy demonstrated that the strains were clearly distinguished into six species based on differences in vegetative cell shape and chloroplast morphology, the number of zoospores within the parental cell and the presence or absence of cell aggregates in old cultures. The six species are Chloromonas chenangoensis, C. fukushimae sp. nov., C. hohamii, C. pichinchae, C. tenuis sp. nov. and C. tughillensis. Although four of the six species formed a small clade based on phylogenetic analysis of multiple genes, their separation was supported by comparison of secondary structures of the internal transcribed spacer 2 of nuclear ribosomal DNA and genetic differences of nuclear- and chloroplast-encoded genes. The present study demonstrated that polyphasic analyses of culture strains of snow Chloromonas species could be used for the identification of natural species.}
