Nomenclatural notes
"This generic name honours Dr. Michael J. Wynne for his valuable contributions to phycology, especially in the taxonomy of the family Delesseriaceae." - (21 Mar 2016) - M.D. Guiry

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.

Numbers of names and species: There is only one species or infraspecific name in the database at present, which has been flagged as accepted taxonomically on the basis of the listed literature under the species name. In some instances, opinions on taxonomic validity differ from author to author and users are encouraged to form their own opinion. AlgaeBase is a work in progress and should not be regarded as a definitive source only as a guide to the literature..

Names: ('C' indicates a name that is accepted taxonomically; 'S' a homotypic or heterotypic synonym; 'U' indicates a name of uncertain taxonomic status, but which has been subjected to some verification nomenclaturally; 'P' indicates a preliminary AlgaeBase entry that has not been subjected to any kind of verification.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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