Description: Cells elongate, unattached or only feebly so, in some species with a spine at each end. Chloroplasts band-shaped, occasionally absent. Cells typically reproduce by the formation of two zoospores which remain motile for a very short time before developing into the coccoid stage. Aplanospores are also known. Zoospores and aplanospores are released by gelatinization and dissolution of the cell wall.

Comments: Klebs (1912) described zoospore germination in C. bataviense, the zoospore settling and increasing in length from 60 µm to 148 µm in 4 min. In some species, formation of a higher number (8-16) of 6-10-µm long cells has been observed, perhaps gametes. Fusion of zoospore-like cells has been reported in a single case, resulting in thick-walled cysts (Pfiester & Lynch 1980).

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,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.
