Abstract

The algae described in this paper appeared in enrichment culture from epiphytic mosses sample collected in southern Zabaikalie (Russia). This organism forms 2–8-celled and 3-dimensional packages of irregular shape. Vegetative cells are spherical, ellipsoidal and ovoid when solitary; cells with thin wall, thickening with age and occasionally with a unipolar manner. The cells and packages are devoid of a gelatinous matrix. There are akinete-like cells with sculptured cell wall. Sexual reproduction is ataktogamic. The results of morphologic and molecular phylogenetic studies allow us to attribute the alga to the genus Chlorosarcinopsis and show a high similarity with C. dissociata and C. bastropiensis. However, obtained data do not prove its identity to any known species of the genus.
