Description: Plants generally colonial; colonies commonly four-celled, with cells joined laterally and oriented in same direction. Cells ellipsoidal or cylindrical with a cell wall. Cells with two equal flagella arising from an apical pole of the cell, a stigma and a cup-shaped chloroplast with single basal pyrenoid. Asexual reproduction by autocolony formation, each cell dividing twice to form a daughter colony within the parental cell wall. Method of sexual reproduction unknown. Oltmannsiella is a rare marine genus and culture studies not reported. Plants generally colonial; colonies commonly four-celled, with cells joined laterally and oriented in same direction.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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