Nomenclatural notes
"Wilsonosiphonia is named in honor of Professor D. Wilson Freshwater for his valuable contributions to the understanding of the systematics of Polysiphonia sensu lato from the western Atlantic." - (28 Apr 2017) - M.D. Guiry

Description: Plants 0.7–3.2 cm, forming predominantly epilithic, intertidal turfs. Thalli composed of extensive and entangled creeping, interwoven, indeterminate prostrate, and erect axes. Ecorticate axes sparsely to moderately dichotomously to subdichotomously branched. Adventitious branches present. Lateral branches replacing trichoblasts. Trichoblasts, if present, long, numerous, delicate, several times forked, deciduous. Conspicuous scar cells present. Rhizoids cut off from distal ends of mature pericentral cells, with taproot-shaped multicellular tips at maturity. Pericentral cells eight to 14 produced from each axial cell. Procarps composed of a supporting cell bearing a four-celled carpogonial branch. Spermatangia replacing or developing as branches of trichoblasts. Tetrasporangia tetrahedral and arranged in spiral series. One or two tetrasporangia produced from a single segment.

Origin of description: this description is from the original publication; it may have been modified slightly.

Numbers of names and species: There are 4 species names in the database at present, of which 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
