Currently accepted name for the type species: Bifurcaria bifurcata R.Ross
Original publication and holotype designation: Stackhouse, J. (1809). Tentamen marino-cryptogamicum, ordinem novum; in genera et species distributum, in Classe XXIVta Linnaei sistens. Mémoires de la Société Imperiale des Naturalistes de Moscou 2: -97.
Taxonomic status: currently recognized as a distinct genus.
Most recent taxonomic treatment adopted: Silberfeld, T., Rousseau, F. & Reviers, B. de (2014). An updated classification of brown algae (Ochrophyta, Phaeophyceae). Cryptogamie Algologie 35(2): 117-156.
Description: Plant consisting of a extensive rhizomatous creeping intertwined perennial basal portion, attached by means of discs from which arise uprights that are terete when vegetative. Growth of uprights from a 3-sided apical cell. Some populations of B. bifurcata with inflations, otherwise evesiculate. Branches from upright system produced in a triradiate fashion, although branching pattern ultimately appearing irregular or bilateral. Swollen terminal portions of the erect system become terete or slightly flattened receptacles. Plants and individual conceptacles monoecious or dioecious, producing one egg per oogonium.

Comments: One species each in the warm temperate north-eastern Atlantic, South Africa and the Galapagos Islands. Species variously in rock pools, on lower shore rock and in the subtidal.
Numbers of names and species: There are 7 species names in the database at present, of which 1 has 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
