Holotype species: Wynneophycus geminatus (Okamura) S.Y.Jeong, B.Y.Won, Fredericq & T.O.Cho

Original publication and holotype designation: Jeong, S.J., Won, B.Y., Fredericq, S. & Cho, T.O. (2016). Wynneophycus geminatus gen. & comb. nov. (Delesseriaceae, Rhodophyta), based on Hypoglossum geminatum Okamura. Phycologia 55(2): 165-177.

Description: Plants epiphytic, erect, membranous, attached to host by small bundles of multicellular rhizoids. Blades originating from an endogenous budding of central axial cells of the midrib, lanceolate to ovate, monostromatic except along the midrib, monopodial, with a distinct corticated midrib. Apices blunt and tapering. Apical cells obconical, segmenting to form an axial filament of cells with two lateral pericentral cells followed by two transverse pericentral cells. Lateral veins absent. Gametophytes dioecious. Procarps borne on transverse pericentral cells on one side of the blades, each with two sterile groups and a four-celled carpogonial branch. Female plants with a basal fusion cell and much-branched gonimoblasts. Pericarp formed by one to three layers of outer cortical cells. Male plants with spermatangial sori between midrib and margin on both sides of primary and second-order blades. Tetrasporangial plants with tetrasporangial sori on second-order blades. Tetrasporangia cut off from pericentral cells and second-order cells, spherical, tetrahedrally divided, each associated with four to five cover cells, arranged in primary cell layer except at midrib.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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