Description: Small pseudoparenchymatous thalli of uniseriate branched filaments. Morphological variation includes attached, nearly circular crusts and irregularly lumpy thalli with mutually free branches at margins. The principal feature of the genus is the relatively long rigid hairs formed from ordinary vegetative cells. Cells cylindrical or rounded to globular, Chloroplast single and parietal with one or a few pyrenoids. Asexual reproduction by quadriflagellate zoospores. Sporangia formed from ordinary vegetative cells that develop a long exit tube. Swarmers with two flagella, probably zoospores, also reported. Ochlochaete species in salt and brackish water as epiphytes, and as part of the thin algal mat that covers small stones, shells, wood, etc.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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