Description: Thalli unicelllar comprised of elongate, strait to highly curved cells, 10-115 x 2.5 µm; one species sigmoid to helically twisted. Ends of cells often highly attenuate and pointed. Cells uninucleate; chloroplasts and pyrenoids absent. Asexual reproduction by aplanospores. Flagellated stages and sexual reproduction unknown.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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