Description: Plants reach 50 cm in height, are erect from crustose holdfasts, and are flattened or terete depending on the species. Central axial cells remain prominent throughout the fronds, and each bears either (2-)3 or 4 periaxial cells, depending again on the species. Spermatangial clusters occur on uniseriate filaments, those of S. furcata (Harvey) J. Agardh also bearing tetrasporangial primordia in addition to spermatangia (Womersley 1971), these being the only tetrasporangia reported for the genus (Searles 1968).

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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