Genera

The Klebsormidiaceae are a family containing three genera of charophyte green alga forming multicellular, non-branching filaments.[2][3] A fourth genus Chlorokybus is sometimes included as well,[4] but this problematic and poorly known genus is sometimes placed in a separate class Chlorokybophyceae.

Klebsormidiacea may be sister to Phragmoplastophyta, together forming a basal Charophyte/Streptophyte clade.

The genera Koliella and Raphidonema were formerly classified as close relatives of Klebsormidium, based on similarities in cell division. However, analysis of both nuclear and chloroplast DNA shows that both of these genera belong to the class Trebouxiophyceae and are not charophytes.[5][6]
