Description: Thalli polysiphonous with 4–14 pericentral cells, ecorticate; trichoblasts absent; both prostrate and erect axes cylindrical, erect axes arising from a prostrate basal system; prostrate axes attached to the substrate by unicellular rhizoids, rhizoids cut off from pericentral cells; erect axes 150–350 µm in diameter, with generally alternate-distichous branching, despite radial development of laterals at the apices; branching to several orders; lateral branches arising at regular intervals from every second or third segment, proximal segments of laterals fused with the bearing axis over 0.5–1.5 segments; terminal ramuli usually incurved and overtopping the apices (giving the false appearance of sympodial growth). Tetrasporangia tetrahedral, with two cover cells, occurring singly per segment in straight series in ultimate and penultimate branches. Cystocarps are globular to ovoid, shortly pedicellate. Male thalli known only in S. robusta, spermatangial branches cylindrical, on short branchlets on ultimate laterals, with 3–4 celled sterile apices.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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