Brachidinium F.J.R.Taylor, 1963
Holotype species: Brachidinium capitatum F.J.R.Taylor
Original publication and holotype designation: Taylor F.J.R. (1963). Brachydinium, a new genus of the Dinococcales from the Indian Ocean. Journal of South African Botany 29: 75-78, pl. 7.
Taxonomic status: currently recognized as a distinct genus.
Most recent taxonomic treatment adopted: Silva, P.C. (1996-to date). Index Nominum Algarum, University Herbarium, University of California, Berkeley http://ucjeps.berkeley.edu/INA.html. Updated continuously. ..
The genus name was validly corrected by F.J.R. Taylor in Nova Hedwigia 12: 443, 1967, as the original spelling 'Branchydinium' was said by Taylor to represent an orthographic error [see Art. 60.1, Melbourne Code] but in respect of priority the genus dates from 1963. This was confirmed by Kanchi Gandhi (e-mail, 22 Sep 2017). - (6 Dec 2011) - M.D. Guiry
Gymnodiniales, Brachidiniaceae. Included in the Kareniaceae by Henrichs et al. (2011). - (9 Jun 2011) - Wendy Guiry
Description: Large (up to 120 µm) compressed cell, in the vegetative stage without flagella, non-motile. Narrow horn-like processes arise from cell body. Cingulum not very distinctive, perhaps reduced but separates the reduced hill-like epicone from the elongated hypocone from which 4 horns emerge, 2 laterally, slightly bent anteriorly and 2 others directed posteriorly. Clearly visible nucleus located in the hypocone; numerous chloroplasts. Sexual reproduction and cyst formation not known. Marine plankton, in temperate to tropical waters of the Indian and Atlantic Ocean, may be abundant

Numbers of names and species: There are 4 species names in the database at present, of which 4 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.
