Original publication and holotype designation: Schmidle, W. (1893). Beiträge zur Algenflora des Schwartzwaldes und der Rheinebene. Bericht der Naturforschenden Gesammelt Freiberg 7: 68-112.

Taxonomic status: currently recognized as a distinct genus.

Most recent taxonomic treatment adopted: Tsarenko, P.M. (2011). Sphaeropleales. In: Algae of Ukraine: diversity, nomenclature, taxonomy, ecology and geography. Volume 3: Chlorophyta. (Tsarenko, P.M., Wasser, S.P. & Nevo, E. Eds), pp. 280-355. Ruggell: A.R.A. Gantner Verlag K.-G..

Description: Thalli microscopic and colonial with 2-4-8 to 64 cells dispersed in homogenous mucilaginous envelope. Cells cylindrical, lunate, sickle-shaped, twisted fusiform or spirally twisted, 3-40 x 1-7 µm, with smooth cell walls. Cells uninucleate; chloroplast single and parietal, pyrenoids 1-4 per cell. Asexual reproduction by autospores, 2-4-8 per sporangium, produced in a series and released by rupture of parental cell wall. Flagellated stages and sexual reproduction unknown. Kirchneriella planktonic or in littoral in freshwater; virtually cosmopolitan in tropical and temperate regions. Genus distinguished from Ankistrodesmus where autospores are not in series, and from Fusola where chloroplasts are multiple. Species distinguished based on cell size and shape. Closteriococcus poorly defined and synonymy with Kirchneriella not accepted by all authorities. Pseudokirchneriella Hindák recently proposed for species without pyrenoids and with smooth cell walls.

Numbers of names and species: There are 36 species names in the database at present, of which 14 have been flagged as accepted taxonomically on the basis of the listed literature under the species name. In some instances, opinions on taxonomic validity differ from author to author and users are encouraged to form their own opinion. AlgaeBase is a work in progress and should not be regarded as a definitive source only as a guide to the literature..

Names: ('C' indicates a name that is accepted taxonomically; 'S' a homotypic or heterotypic synonym; 'U' indicates a name of uncertain taxonomic status, but which has been subjected to some verification nomenclaturally; 'P' indicates a preliminary AlgaeBase entry that has not been subjected to any kind of verification.

Contributors
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in CD format. These AlgaeBase descriptions are now being continually updated, and each current contributor is identified above. The PSA and AlgaeBase warmly acknowledge the generosity of all past and present contributors and particularly the work of Dr Parker.

Descriptions of chrysophyte genera were subsequently published in J. Kristiansen & H.R. Preisig (eds.). 2001. Encyclopedia of Chrysophyte Genera. Bibliotheca Phycologica 110: 1-260.
