Zosterocarpus Bornet, 1890

Holotype species: Zosterocarpus oedogonium (Meneghini) Bornet

Original publication and holotype designation: Bornet, É. (1890). Note sur deux algues de la Méditerranée: Fauchea et Zosterocarpus. Bulletin de la Société Botanique de France 37: 139-148, 5 figs, 1 plate.

Description: Uniseriate branched filaments with terminal cells tapering to a point. Growth largely by division within scattered zones of intercalary cells. Vegetative cells containing numerous small discoid chloroplasts without pyrenoids. The type species and Z. abyssicolus with swollen, tannin-filled cells scattered intercalary in short laterals. Reproduction by plurilocular zoidangia formed by outward segmentation of cells of laterals, often resulting in a corticating ring of fertile locules around a vegetative cell.

Taxonomic status: This name is of an entity that is currently accepted taxonomically.

Gender: This genus name is currently treated as masculine.

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, 1 fig., 1 table.

Comments: Although most commonly treated as a member of the Ectocarpales, this practice is confounded by the presence of numerous small discoid chloroplasts without pyrenoids. Funk (1955) treated Zosterocarpus as a member of the Tilopteridales, and this is supported by the nature of the chloroplast and the meristem. The recent addition of Phaeosiphoniella to the Tilopteridales (Hooper and others 1988) suggests that the corticating plurilocular structures of Zosterocarpus provide further evidence of the affinity of the latter genus with this order.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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