Holotype species: Dendrocystis raoi M.O.P.Iyengar
Original publication and holotype designation: Iyengar, M.O.P. (1962). Dendrocystis raoi gen. et sp. nov., a new dendroid member of the Chlorococcales. Phykos 1: 1-15, 12 figs.
Taxonomic status: currently recognized as a distinct genus.
Description: Thalli forming microscopic dendroid, dichotomously branching colonies to 180 &m tall and 150 &m wide, attached by mucilage pad of initial basal cell. Colonies develop by longitudinal cell division and migration and attachment of both daughter cells to apex of parental wall. Cells ellipsoid, 24-36 x 10-16 &m. Cell walls smooth, with or without 3-6 elongate, straight or curved, hollow spines to 16-22 &m long. Cells with central nucleus and two large lipid bodies inside vacuoles; chloroplast diffuse and laminate with numerous starch grains; pyrenoids absent. Asexual reproduction poorly known, presumably by release of paired? autospores from cells of colony. Flagellated stages and sexual reproduction unknown. Dendrocystis known only from South India growing on stones in small stream.

Numbers of names and species: There is only one species or infraspecific name in the database at present, which 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
