چکیده

The taxonomy of green microalgae relies traditionally on morphological traits but has been rapidly changing since the advent molecular methods. Stichococcus Nägeli is a cosmopolitan terrestrial algal genus class Trebouxiophyceae that recently split into seven lineages, which, along with Pseudostichococcus, comprise Stichococcus-like group; there need to further characterize these genera, they are morphologically enigmatic. Here we used organic osmolytes as chemotaxonomic marker verify phylogenetic position strains and were also able exclude strain hitherto identified Gloeotila contorta from this group. organisms, including those revised, characterized by production polyol sorbitol disaccharide sucrose in high amounts, typical Prasiola-clade algae. results demonstrate osmolyte chemotaxonomy can support taxonomic designations fundamental research. Key words: aeroterrestrial algae; chemotaxonomy; osmolytes; Pseudostichococcus; sorbitol; Stichococcus;
