Comments: Ettl transferred most members of the genus Pseudocarteria from the genus Carteria. Ettl describes Pseudocarteria as a parallel to Carteria. The two differ in that the former exhibits multiple (>2) contractile vacuoles scattered throughout the cytoplasm and the latter typically exhibits two (or four) anterior contractile vacuoles. Pseudocarteria is known from continental Europe, the United States, and Japan. Pseudocarteria has been collected as plankton, in rain-water pools, and in small eutrophic bodies of water. No biochemical or molecular data are available for this organism

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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