Holotype species: Ochlochaete hystrix Thwaites
Original publication and holotype designation: Harvey, W.H. (1849). Phycologia britannica, or, a history of British sea-weeds: containing coloured figures, generic and specific characters, synonymes, and descriptions of all the species of algae inhabiting the shores of the British Islands. pp. text with plates, pls CCXVII-CCLXX [217-270]. London: Reeve & Benham.
Taxonomic status: currently recognized as a distinct genus.
Gender: This genus name is currently treated as feminine.
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.

Numbers of names and species: There are 11 species names in the database at present, as well as 3 infraspecific names. Of the species names, 3 have been flagged as accepted taxonomically on the basis of the listed literature under the species name. In some instances, opinions on taxonomic validity differ from author to author and users are encouraged to form their own opinion. AlgaeBase is a work in progress and should not be regarded as a definitive source only as a guide to the literature..
Names: ('C' indicates a name that is accepted taxonomically; 'S' a homotypic or heterotypic synonym; 'U' indicates a name of uncertain taxonomic status, but which has been subjected to some verification nomenclaturally; 'P' indicates a preliminary AlgaeBase entry that has not been subjected to any kind of verification.

Verification of data
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
