Taxonomic status: currently recognized as a distinct genus.

Most recent taxonomic treatment adopted: Schneider, C.W. & Wynne, M.J. (2007). A synoptic review of the classification of red algal genera a half a century after Kylin's "Die Gattungen der Rhodophyceen". Botanica Marina 50: 197-249.

Description: Thallus less than 2 cm high, of ecorticate branched prostrate axes bearing subdichotomous branches often consisting of free ends of prostrate axes and bearing whorls of up to 7 simple or subdichotomous determinate branchlets on each cell. Procarps borne on supporting cell cut off from sub-apical cell of a 3-celled fertile axis developed in place of a determinate branchlet. Carpogonium of 4-celled carpogonial branch connects with auxiliary cell cut off from supporting cell. Gonimoblast surrounded by involucral branches and fusion cell formed from supporting cell, auxiliary cell and subapical cell of the fertile axis. Gonimolobes form a cystocarp composed of carposporangia. Spermatangial fascicles and 2-5 tetrahedral tetrasporangia borne on basal cells of determinate branchlets. Morphological and reproductive features suggest Baldockia as a primitive member of Griffithsieae superficially similar to Halurus equisetifolius (Lightfoot) K├╝tzing.

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.

Contributors
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
