Rhizochloris Pascher, 1917

Holotype species: Rhizochloris mirabilis Pascher

Original publication and holotype designation: Pascher, A. (1917). Flagellaten und Rhizopoden in ihrer gegenseitigen Beziehungen. Archiv für Protistenkunde 38: 1-87.

Description: Unicellular, amoeboid, free-living organisms (4)-8 to 18 (80) &m with large, wide pseudopodia or fine, elongated rhizopodia to 20 &m. Sometimes daughter cells form cytoplasmic filaments or loose, irregular groups in which cells remain independent. Chloroplasts small and discoid, mostly six per cell (sometimes two to four), without pyrenoids. Most species with stigma, and in freshwater with contractile vacuoles. Cells contain lipid or oil granules and these globules are strongly refringent and probably comprised of chrysolaminarin. Additional nutrition provided by capture of small organisms by pseudopodia. Asexual reproduction by division of cells. Cysts known from one species (cysts 8 &m). Rhizochloris known from fresh, brackish or marine waters in Europe. Species distinguished based on chloroplast number, presence or absence or stigmata, movement of pseudopodia and the ability of cells to form groups.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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