Request PDFDescription: Single cells 10-18 _m long and 7-10 _m wide, flattened with an irregular to elliptical or ovoid outline. Cell walls absent. Cell anterior elongated with a basal, cytopharynx depression in which a single flagellum is inserted. Flagellar length one to two times as long as the cell. Cells with rapid sliding motion based on flagellar beating. Chloroplasts two per cell (sometimes one or three), plate or cup shaped and parietal. A single leucosin granule in cell posterior. Cells without stigma, contractile vacuoles and pyrenoids. Asexual division by longitudinal division of motile cells. Resistant cells have never been observed although cyst envelopes (double) common. Beckingia in marine or brackish water; rarely observed and only in cultures from southern Australia and the former Czechoslovakia.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,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.
