Holotype species: Womersleyella pacifica Hollenberg
Original publication and holotype designation: Hollenberg, G.J. (1967). New genera in the Rhodomelaceae from the Central Pacific. Bulletin of the Southern California Academy of Sciences 66: 201-221, 15 figs.
Taxonomic status: currently recognized as a distinct genus.
Most recent taxonomic treatment adopted: Schneider, C.W. & Wynne, M.J. (2007). A synoptic review of the classification of red algal genera a half a century after Kylin's "Die Gattungen der Rhodophyceen". Botanica Marina 50: 197-249.
Description: Thallus with indeterminate prostrate axes bearing erect determinate branches, these arising randomly or occasionally in pairs separated by a few segments. Structure with 4 or 5 pericentral cells, ecorticate. Emergent or dormant trichoblasts developing 1 per segment in a spiral pattern; in prostrate axes often remaining dormant for some time before producing some dorsal determinate branches; trichoblasts in determinate branches emergent. Prostrate axes attached by rhizoids cut off from the ventral pericentral cell, these unicellular except for their multicellular tips. Spermatangial heads replacing trichoblasts, with sterile tips. Cystocarps ovoid to urceolate, with an ostiole. Tetrasporangia 1 per segment in spiral series. Cystocarps and spermatangial heads near distal ends of branches.

Numbers of names and species: There are 4 species names in the database at present, as well as 1 infraspecific names. Of the species names, 4 have 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.

Verification of data
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
