Description: Unicellular - colonial; colonies irregular, gelatinous, in outline more or less spherical, hemispherical or flat and grumose, micro- to macroscopic, attached to the substrate or free-living, epipelic or in metaphyton, sometimes form gelatinous masses composed from single microcolonies. Cells arranged in common mucilage of colonies usually in rows (sometimes indistinct), sometimes radially or parallel oriented, usually without their own envelopes. Cells more or less spherical, ellipsoidal or irregular, with blue-green, grayish, pale olive-green, yellowish or reddish, finely granular content. Cells divide in three or more planes in successive generations and grow more or less into the original size (not shape) before the next division. Described also are planocyte and nanocyte formations (relation to the family Xenococcaceae ?). Reproduction usually by the fragmentation of colonies into several-celled mucilaginous clusters. Type species and two further species are known from the marine littoral (epiphytic or epilithic), 2 species from hypersaline lakes in central-Asiatic USSR and in deserts of Egypt. Most species described from freshwater biotopes, usually from littoral and benthos of lakes and mountain creeks. One species is aerophytic (growing on limestone rocks, in caves and shaded placed). Two species are known only from tropics, 2 species only from Antarctica.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,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