Most recent taxonomic treatment adopted: Massjuk, N.P. & Lilitska, G.G. (2011). Dunaliellales. In: Algae of Ukraine: diversity, nomenclature, taxonomy, ecology and geography. Volume 3: Chlorophyta. (Tsarenko, P.M., Wasser, S.P. & Nevo, E. Eds), pp. 152-157. Ruggell: A.R.A. Gantner Verlag K.-G..
Description: Unicellular, uninucleate and quadriflagellate algae devoid of cellulosic cell walls. Cell shape variable but mostly obovoid to ellipsoid. Lateral margins somewhat angular with a broad, truncately-rounded apex, narrowing to the posterior which may bear 1-3 lobes or be simply broadly rounded. Cell posterior often pseudopodial. Nucleus typically posterior. Cells withoutchloroplasts and stigmata. Cytoplasm heavily vacuolate with two or more contractile vacuoles. Asexual reproduction by cell division; sexual reproduction unknown.

Comments: Collodictyon> has two well-described species, C. tricellatumH.J.Carter and C. sparsevacuolatum Skuja reported from freshwater in Europe and the United States. C. hongkongense Skvortzov is inadequatelydescribed. The assignment of the marine C. sphaericum R.E.Norris to Collodictyonwas questioned by Ettl
Numbers of names and species: There are 4 species names in the database at present, of which 4 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.

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
