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.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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