Nomenclatural notes
ING has a lectotype of Vickersia baccata (J.Agardh) Karsakoff selected by Børgesen (1930: 20). However, Athanasiadis (2016: 1012) lists "(typ: V. canariensis, De Toni 1924: 466)," who clearly says "Species typica generis, Vickersia canariensis Kars.,...". - (25 Jan 2017) - M.D. Guiry

Description: Thallus prostrate and erect, axes ecorticate, each cell swollen, claviform, multinucleate and bearing a whorl of 1-4 determinate branchlets. Procarps subapical, 4-celled carpogonial branch on one (supporting cell) of 3 pericentral cells, post fertilization stages unknown, carposporophyte with terminal carposporangia surrounded by involucral filaments. Spermatangial heads on basal cells of branchlets. Tetrasporangia sessile, numerous (to 5O or more) on basal cells of 2-celled determinate branchlets, tetrahedrally divided. Distinctive in the unusually large number of sporangia on each fertile cell.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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