Taxonomic notes
The Family Wurdemanniaceae, questionably distinct from the Solieriaceae on anatomical grounds, were recently subsumed into the latter family by Saunders et al. (2004) based on small-subunit rDNA sequence studies. - (25 Jul 2006) -

Description: Plants are multiaxial and nearly pseudoparenchymatous in cross section, the medullary cells being longitudinally elongate. Tetrasporangia are zonate, the sporangia aggregated in slightly swollen tips of fertile axes. Sexual reproduction is unknown. Plants reach 5 cm in height and form tufts or turfs of wiry erect axes arising from entangled rhizomatous bases. Cells of the central medulla are elongate and thin-walled, becoming shorter and thicker-walled peripherally. Plants are multiaxial and nearly pseudoparenchymatous in cross section, the medullary cells being longitudinally elongate. Tetrasporangia are zonate, the sporangia aggregated in slightly swollen tips of fertile axes. Sexual reproduction is unknown.

Comments: Distribution: From North Carolina southward throughout the Carribbean; Mediterranean Sea and possibly the Indian and western Pacific Oceans, often intertidally in surf zones (Taylor 1960) but also dredged from deep water (Boergesen, 1920). The Family Wurdemanniaceae, questionably distinct from the Solieriaceae on anatomical grounds, were recently subsumed into the latter family by Saunders et al. (2004) based on small-subunit rDNA sequence studies.

Numbers of names and species: There are 2 species names in the database at present, of which 1 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
