Taxonomic status: currently recognized as a distinct genus.

Gender: This genus name is currently treated as feminine.

Most recent taxonomic treatment adopted: Silberfeld, T., Rousseau, F. & Reviers, B. de (2014). An updated classification of brown algae (Ochrophyta, Phaeophyceae). Cryptogamie Algologie 35(2): 117-156.

Description: Sporophytes annual, a single stipe attached initially by a small disc, sometimes with a few short haptera, soon covered by a discoid circumferential swelling (rhizogen) of the stipe, which forms downward-growing hapteroid protuberances that surround the initial holdfast, succeeded by one or more whorls of haptera; all haptera unbranched. Stipe flattened, broadening to form a single lanceolate or expanded and split blade. Hair-pits on young blades, deciduous with age; costae lacking. Medulla containing long, thick-walled longitudinal conducting cells (solenocysts) and lateral connecting cells (allelocysts) rather than sieve tubes. Mucilage ducts absent. Sporangia sori discontinuous patches at base of blades, paraphyses lacking a hyaline appendage, zoospores with a red eyespot. Gametophytes of S. polyschides dioecious and sexually dimorphic, those of S. dermatodea monoecious. Marine, littoral to 19 m, distributed either in the western Mediterranean and the Atlantic from the Tropic of Cancer to southern Norway (S. polyschides), or from Novaya Zemblya to Norway, Ellesmere I., and northern Massachusetts (S. dermatodea).

Numbers of names and species: There are 3 species names in the database at present, as well as 1 infraspecific names. Of the species names, 2 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.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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