Description: Unicellular - pseudofilamentous; thallus creeping on the substrate (mainly on stones), crust-like or in a thin layer, composed of irregular groups of cells (chroococcacean state), from which grow irregular or radial rows of cells, sometimes irregularly branched; in several species are the pseudofilaments endolithic; rows of cells uni- or multicellular, enveloped by more or less thin, firm, sometimes lamellated and yellowish-brownish colored sheaths confluent together by their sides. Cells irregular, of different size, sometimes (in pseudofilaments) slightly elongated, with homogeneous or slightly granular content, sometimes with several prominent granules, bluegreen, pale blue-green or pinkish. Cells divide irregularly in different planes; enlarged cells from different parts of thallus divide sometimes in nanocytes. Reproduction by nanocytes. Type species and several other taxa known from marine littorals (surf or intertidal zones); freshwater species known usually from clear mountain streams or from the stony surf -zones of unpolluted lakes and reservoirs, worldwide. Most species grow on limestone substrates.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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