Description: Plants globose, tuberculose or arbuscular, mucilaginous or somewhat cartilaginous. Thalli comprised of highly branched, intertwined, uniseriate filaments, each branch tapering to a blunt point or giving rise to a long, multicellular hair. Cells each with parietal chloroplast and one to several pyrenoids. Motile stages produced from peripheral cells, zoospores quadriflagellate and gametes biflagellate and isogamous. Emended diagnosis (Kützing, 1843 fide Liu et al., 2019).

Taxonomic status: This name is of an entity that is currently accepted taxonomically.

Gender: This genus name is currently treated as feminine.

Most recent taxonomic treatment adopted: Caisová, L., Marin, B., Sausen, N., Proschold, T. & Melkonian, M. (2011). Polyphyly of Chaetophora and Stigeoclonium within the Chaetophorales (Chlorophyceae), revealed by sequence comparisons of nuclear-encoded SSU rRNA genes. Journal of Phycology 47(1): 164-177.

Comments: Species grow epiphytically on freshwater aquatic plants and a wide variety of other submerged surfaces. Widely distributed. Requires re-investigation as species distinguished principally on such unreliable criteria as macroscopic thallus form and nature of branching of the constituent filaments. Ultrastructural investigation of C. incrassata shows plasmodesmata, a phycoplast, and membranes appressed to pyrenoids.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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