"...named for Dr Amanda M. Savoie, who with her co-author and PhD supervisor Dr Gary W. Saunders, demonstrated the generic distinctiveness of this clade of species within the Tribe Pterosiphonieae." - (28 Jul 2018) - M.D. Guiry
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.
Origin of description: this description is from the original publication; it may have been modified slightly.
Numbers of names and species: There are 4 species names in the database at present, of which 4 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
