Taxonomic status: currently recognized as a distinct genus.

Most recent taxonomic treatment adopted: Kristiansen, J. & Preisig, H.R. (2001). Encyclopedia of Chrysophyte genera. Bibliotheca Phycologica 110: 1-260.

Description: Cells naked, metabolic, forming simple or branched rhizopodia from their surface. Often loose, few-celled colonies are formed. Some species form flagellated stages with one visible flagellum, and a very short second flagellum only seen in EM, in other species (previously included in Rhizochrysis) flagellated stages are not known. Cells have 1-2 chloroplasts without stigma, but with contractile vacuoles. Reproduction by cell division. Stomatocysts globular, smooth, with short collar, known from several species. At germination amoeboid zoospores are released. Found in ponds, lakes and turf pits, also in marine habitats worldwide. Many species from different genera, especially in the Chromulinales, may temporarily occur as rhizopodial stages that resemble Chrysamoeba.

Numbers of names and species: There are 14 species names in the database at present, of which 8 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
