Holotype species: Husseyella australis (J.Agardh) Papenfuss
Currently accepted name for the type species: Husseya rubra (Harvey) P.C.Silva
Original publication and holotype designation: Papenfuss, G.F. (1958). Notes on algal nomenclature. IV. Various genera and species of Chlorophyceae, Phaeophyceae and Rhodophyceae. Taxon 7: 104-109.
Taxonomic status: currently regarded as a synonym of Husseya.
Description: Thalli polysiphonous, up to 30 cm tall, highly branched, proximal axis up to ca. 2.0 mm diameter, distal branchlets approximately 400 &m in diamter. Branches radially arranged, often alternate distally, sometimes with branchlets produced in axils of primary branches. Actively growing branch apices with an apical depression. Five pericentrals ringed by a layer of large cells that are covered by cortication, and an epidermal layer of rectangular cells; some cortication rhizoidal, but the epidermal layer produces a thick pseudoparenchymatous cortical layer in older axes. Some pericentral cells produce cell wall thickenings that may become massive and form laminated refringent bands (Gordon-Mills and Womersley (1984). Tetrasporangia borne in cortical region of short branchlets borne in clusters on distal branches. Sporangia tetrahedrally divided but details of development and number per axial cell are not available. Procarps borne on short branchlets occurring in clusters on distal thallus branches. Cystocarps borne singly or in pairs, ovoid to spheroidal, and on a short pedicel. Male plants remain unknown.

Verification of data

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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