Description: Unicellular flagellates with single emergent flagellum. Cells asymmetric, compressed, with the flagellum emerging tangentially from the narrow side. Cells usually stationary with flagellum curved around the cell. In swimming cells the flagellum trails behind the cell. The flagellum carries rigid hairs. Base of flagellum inserted in deep pocket. Outer edge of the pocket thickened to form a lip. Cell surrounded by close-fitting lorica except at the anterior end which is naked. Single green parietal chloroplast with immersed pyrenoid. Eyespot opposite the flagellar insertion, on the surface of the pyrenoid. Detailed study on ultrastructure by Jones and others (1994). Sexual reproduction or resting stages unknown. Marsupiomonas differs from the other members of the Pedinophyceae mainly in the presence of the close-fitting, bowl-shaped lorica, while species of other genera are naked.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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