Description: Thallus uniseriate, branched filamentous; growth via transverse division of an apical cell; primary branching, from subapical cells, sparse and irregular; secondary branching originated by formation of lenticular cells from the lateral walls of the filaments; these cells elongating and functioning as apical cells, giving rise to determinate and indeterminate branches as well as much-branched colorless filaments (hyphae), the latter forming a woolly mantle around the older filaments. Each cell with several more or less stellate parietal chloroplasts, each with a pyrenoid. Tetrasporangia lateral or terminal on small, more or less ramified, branchlets; tetrasporangia with cruciate (or apparently tetrahedral) division. Gametophytes and life history unknown. Type species marine, epilithic, widespread circumsubantarctic (S. America, Australia, New Zealand). traditionally assigned to the Ceramiaceae, in the genus Ballia; transferred to Acrochaetiaceae mainly because of possession of pyrenoids, but plant and cell size far bigger than in any other member of the family. So far only the type species assigned to Camontagnea, but Ballia hirsuta Wollaston is very close to this genus.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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