Holotype species: Ballia brunonia Harvey
Currently accepted name for the type species: Ballia callitricha (C.Agardh) Kützing
Original publication and holotype designation: Harvey, W.H. (1840). Description of Ballia, a new genus of algae. Journal of Botany [Hooker] 2: 190-193, pl. IX.A.
Taxonomic status: currently recognized as a distinct genus.
Most recent taxonomic treatment adopted: Choi, H.-G., Kraft, G.T. & Saunders, G.W. (2000). Nuclear small-subunit rDNA sequences from Ballia spp. (Rhodophyta): proposal of the Balliales ord. nov., Balliaceae fam. nov., Ballia nana sp. nov. and Inkyuleea gen. nov. (Ceramiales). Phycologia 39: 272-287.
"The generic name is bestowed in honour of Miss Anne E. Ball of Youghal [Co. Cork, Ireland], a most successful and zealous algologist, who has added numerous new species to the Irish Flora, among which is the rare Sporochnus Cabrera." - (14 Mar 2011) - M.D. Guiry
Description: Thallus usually over 15 cm high verying in form. Axes developed from large apical cell, densely corticated with short branches borne on basal cells of determinate branchlets, and descending rhizoidal filaments bearing outwardly projecting branches. Axial cells closely adjacent, specialized in some species, each with 2-3 distichous to tristichous regularly-branched determinate branchlets. Pit connections in most species capped on either side by dome-shaped structures unknown in related genera. Gland cells lacking. Sexual plants rare and poorly known in most species. B. mariana and B. ballioides with 4-celled carpogonial branch from upper side of supporting cell and carposporophyte bearing rounded groups of carposporangia developed from a 4-celled auxiliary cell branch. Tetrasporangia known for most species.

Comments: Ballia shows regular, specialized organization in vegetative and reproductive features and is at present retained as a phylogenetieally advanced member of Antithamnieae. B. scoparia and B. hirsuta (southern Australia) show marked morphological differences from other species, but included in Ballia until reproduction known. Common in southern Australia, especially B. callitricha, also South Africa and cold to temperate seas.
Numbers of names and species: There are 18 species names in the database at present, as well as 6 infraspecific names. Of the species names, 7 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.
