Description: Erect thalli branched filiformis, solid, parenchymatous, composed of inner cells and one to several layers of pigmented peripheral cells, attached with rhizoidal holdfast. Terminal and lateral phaeophycean hairs present. Growth diffuse. Cells contain many discoidal chloroplasts without pyrenoids. Unilocular sporangia formed from peripheral cells. Plurilocular sporangia very variable in shape, appear intercalary at the terminal thin parts of the thallus. Unispores and plurispores pear-shaped with one chloroplast with stigma, normally biflagellated. Sexual reproduction unknown. Rosenvinge (1935) reported heteromorphic life history in S. tortilis , and Rosenvinge (1935), Sauvageau (1929) and South and Hooper (1976) reported direct type of life history in S. soriferus and S. adriaticus.

Numbers of names and species: There are 14 species names in the database at present, of which 10 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
