Dunaliella Teodoresco, 1905
Holotype species: Dunaliella salina (Dunal) Teodoresco
Original publication and holotype designation: Teodoresco, E.C. (1905). Organisation et développement du Dunaliella, nouveau genre de Volvocacée - Polyblepharidée. Beihefte zum Botanischen Centralblatt 18(Abt. 1): 215-232.
Description: Unicellular,biflagellate and uninucleate algae without cellulosic cell walls, oftenwith considerable metaboly. Cells fusiform, ellipsoid, ovoid, obovoid,globose or depressed-globose. Anterior end usually rounded or slightlyacuminate; posterior end rounded, or in some cases, caudate. Chloroplastparietal and principally cup-shaped; pyrenoid and stigma present orabsent. Nucleus typically in anterior end along with two contractilevacuoles, these may be quite indistinct in freshwater. Cytoplasmicorganization may be masked by accumulations of haematochrome pigment.Asexualreproduction by cell division sometimes giving rise to a palmelloid stage;occasionally cells become encysted. Sexual reproduction by fusion ofisogametes; zygote typically thin walled, occasionally ornamented. Upongermination, 4-8(-16) zoospores released.

Comments: Dunaliella spp. widely distributed in marine or brackish waterhabitats. Four species, D. acidophila (Kalina) Masjuk, D. carpaticaMasjuk, D. lateralis Pascher et Jahoda and D. pauperaPascher, may be found in freshwater or slightly brackish habitats; otherspecies, notably D. salina and D. viridis Teodoresco, may befound in inland salterns and brine lakes.
Verification of Data
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
