Request PDFDescription: Unicellular-colonial; colonies microscopic, containing usually relatively small number of cells, only old colonies rarely with many cells, mucilaginous, with more or less elongated cells, loosely arranged, distant from one another, oriented more or less in one direction or in loose rows (this position is disturbed in old colonies); colonial slime colorless, without structure, homogeneous and usually diffluent at the margin. Sometimes few small colonies clustered together. Cells long oval to rod-like, rounded at the ends, straight, arcuate or sigmoid, with pale blue-green, rarely pinkish homogeneous content. Involution cells filament-like. Cell division (binary fission) by cleavage, always perpendicular to the longer axis of cells, in involution cells sometimes irregularly (asymmetrical). Daughter cells separate from one another, or form short pseudofilamentous rows. Reproduction by dissociation of colonies and by solitary cells. Several planktonic species, a few taxa described from metaphyton and detritus in unpolluted aquatic biotopes with numerous aquatic plants. One species is cryosestonic, one known from saline water.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,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