Hincksia J.E.Gray, 1864
Holotype species: Hincksia ramulosa J.E.Gray
Currently accepted name for the type species: Hincksia hincksiae (Harvey) P.C.Silva
Original publication and holotype designation: Gray, J.E. (1864). Handbook of British water-weeds or algae. The Diatomaceae by W. Carruthers. pp. i-iv, 1-123. London: R. Hardwicke, Picadilly.
Taxonomic status: currently recognized as a distinct genus.
Gender: This genus name is currently treated as feminine.
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: The erect thallus of this cosmopolitan genus consists of uniseriate, branched filaments. Growth is diffuse intercalary. The chloroplasts are parietal, disc-shaped, numerous in each cell and each chloroplast has one pyrenoid. True phaeophycean hairs unknown. The branching pattern within the genus varies. It may be secund, but also species with scattered or opposite branches occur. Also the position of the often sessile plurilocular sporangia varies. In some species they are formed by transformation of short laterals coming from the adaxial side of the supporting lateral giving this a serrate appearance, but they also occur on the main axis. Unilocular sporangia seldom occur and they have the same position on the filaments as the plurilocular sporangia. The life history of H. ovata (Kjellm.) P. C. Silva is of the direct type (Kornmann 1954, as Giffordia fuscata, Pedersen 1979, as G. ovata). The unilocular sporangia observed in Kornmann's studies are probably apomeiotic.

Numbers of names and species: There are 40 species names in the database at present, as well as 5 infraspecific names. Of the species names, 32 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.
