Klebsormidiaceae
The Klebsormidiaceae are a family containing five genera of charophyte green alga forming multicellular, non-branching filaments. The genus '' Chlorokybus'' was previously included as well, but this problematic and poorly known genus is now placed in a separate class Chlorokybophyceae. Klebsormidiaceae are the sister to the Phragmoplastophyta. Their ancestor was probably a multicellular freshwater green algae, and multicellularity will be retained in all of its descendants except the Zygnematophyceae, which reverted back to unicellularity. Together with the unicellular Chlorokybophytina (Mesostigmatophyceae, ''Spirotaenia'' and Chlorokybophyceae), they comprise the Streptophyta. 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. '' In ...

Phragmoplastophyta
The Phragmoplastophyta (Lecointre & Guyader 2006) are a proposed sister clade of the Klebsormidiaceae in the Streptophyte/Charophyte clade. The Phragmoplastophyta consist of the Charophycaea and another unnamed clade which contains the Coleochaetophyceae, Zygnematophyceae, Mesotaeniaceae, and Embryophytes (land plants). It is an important step in the emergence of land plants within the green algae. It is equivalent to the ZCC clade/grade, cladistically granting the Embryophyta. The mitosis of Phragmoplastophyta takes place via a phragmoplast. Another synapomorphy In phylogenetics, an apomorphy (or derived trait) is a novel character or character state that has evolved from its ancestral form (or plesiomorphy). A synapomorphy is an apomorphy shared by two or more taxa and is therefore hypothesized to hav ... of this clade is the synthesis of cellulose microfibrils by a complex of octameric cellulose synthetases.

Klebsormidium Bilatum
''Klebsormidium'' is a genus of filamentous charophyte green algae comprising 20 species. The name was proposed in 1972 to resolve confusion in application and status of Hormidium and was given for the German botanist Georg Albrecht Klebs. The algae occurs mostly in soil and on moist substrates, nevertheless, aquatic and one marine species are also known. Many ''Klebsormidium''-species are able to synthesize substances for UV protection, the so-called mycosporine-like amino acids. The draft genome sequence of ''Klebsormidium flaccidum'' was published in 2014. Species The valid species currently considered to belong to this genus are: * '' Klebsormidium acidophilum'' * '' Klebsormidium bilatum'' * ''Klebsormidium crenulatum'' * ''Klebsormidium dissectum'' * ''Klebsormidium drouetii'' * ''Klebsormidium elegans'' * ''Klebsormidium fluitans'' * ''Klebsormidium fragile'' * ''Klebsormidium klebsii'' * ''Klebsormidium lamellosum'' * ''Klebsormidium montanum'' * ''Klebsormidium mu ...

Spirotaenia
''Spirotaenia'' is a genus of basal green algae that may be sister to the Chlorokybophyceae. It was previously considered to be part of the Zygnemataceae. It is sexually conjugating, a mode of reproduction that was previously only known in the Zygnemataceae/Mesotaeniaceae, the sister groups to the land plants The Embryophyta (), or land plants, are the most familiar group of green plants that comprise vegetation on Earth. Embryophytes () have a common ancestor with green algae, having emerged within the Phragmoplastophyta clade of green algae as sist .... This is surprising, as ''Spirotaenia'' is much more basal. The conjugating process is substantially aberrant. ''Spirotaenia'' may actually be more than one distinct lineage which may not be closely related. Phylogeny References Green algae {{Alga-stub ...

Koliella
''Koliella'' is a genus of green algae in the order Prasiolales. The genus name of ''Koliella'' is in honour of Erszébet (Elizabet) Kol (1897-1980), who was a Hungarian botanist (Mycology and Algology), who worked at the Hungarian National Museum in Budapest. The genus was circumscribed In geometry, the circumscribed circle or circumcircle of a polygon is a circle that passes through all the vertices of the polygon.

Streptophyta
Streptophyta (), informally the streptophytes (, from the Greek ''strepto'' 'twisted', for the morphology of the sperm of some members), is a clade of plants. The composition of the clade varies considerably between authors, but the definition employed here includes land plants and all green algae except the Chlorophyta and the more basal Prasinodermophyta. Classifications The composition of Streptophyta and similar groups (Streptophytina, Charophyta) varies in each classification. Some authors are more restrictive, including only the Charales and Embryophyta (e.g., Streptophyta Jeffrey 1967; Adl et al. 2012, Streptophytina Lewis & McCourt 2004), others include more groups (e.g., Charophyta Lewis & McCourt 2004; Karol et al. 2009; Adl et al. 2012, Streptophyta Bremer, 1985; de Reviers 2002; Leliaert et al. 2012, Streptobionta Kenrick & Crane 1997; some authors use this broader definition, but exclude the Embryophyta, e.g., Charophyta Cavalier-Smith 1993; Leliaert et al. 2012, C ...
