Taxonomic status: currently recognized as a distinct genus.

Most recent taxonomic treatment adopted: Silberfeld, T., Rousseau, F. & Reviers, B. de (2014). An updated classification of brown algae (Ochrophyta, Phaeophyceae). Cryptogamie Algologie 35(2): 117-156.

Description: Thallus flattened, ribbon-like, erect, with smooth margins; attached by rhizoids restricted to the basal parts of the thallus; stoloniferous holdfasts present, restricted to the base or emerging from the surface as well as from deformed apices; branching dichotomous to anisotomous; apices rounded; apical cell protruding to somewhat emarginate; phaeophycean hairs present; surface proliferations present or absent; surface undulating or rugose inmature thalli; cortex predominantly unilayered, with occasional duplications in the basal parts; medulla uniformly unilayered except for the stoloniferous holdfasts or multilayered near the margins; reproductive structures confined to concavities of the thallus surface; sporangia in small sori or in blocklike patches, surrounded by an inconspicuous involucrum, with two stalk cells; antheridia subtended by a stalk cell, in sori surrounded by pigmented multicellular paraphyses; oogonia subtended by a stalk cell, grouped in sori or small-scattered groups.

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.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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