Original publication and holotype designation: Skottsberg, C. (1953). On two collections of Antarctic marine algae. Arkiv für Botanik, ser. 2, 2: 531-566, 1 pl.

Precise date of publication13 May 1953

Taxonomic status: currently recognized as a distinct genus.

Gender: This genus name is currently treated as masculine.

Most recent taxonomic treatment adopted: Schneider, C.W. & Wynne, M.J. (2007). A synoptic review of the classification of red algal genera a half a century after Kylin's "Die Gattungen der Rhodophyceen". Botanica Marina 50: 197-249.

Description: Thalli minute, pulvinate, almost without pigment, growing on Picconiella, the pulvinate tissue anchored by filaments growing between the host's pericentral cells. Erect, unbranched, polysiphonous branches with 8-10 pericentrals produced from cushion; branches soon become corticated and produce reproductive structures. Reproductive branches erect, radiating from surface of pulvinate tissue. Male thalli with spermatangia produced from surface bearing cells that cover all but the proximal part of branch. Female branches with many procarps; several fertilized resulting in up to 8 cystocarps on fertile branch. Cystocarps spheroidal, partly sunken in branch. Tetrasporophytes with claviform branchlets up to 2 mm long, tetrasporangia borne beneath outer cortical cells in several spiral series over most of branch length.

Comments: On host, Picconiella, in Chilean Antarctica and southern Argentina (Pujals 1963).

Numbers of names and species: There is only one species or infraspecific name in the database at present, which has 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.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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