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: Plants composed of rhizomatous perennial basal disc and annual erect thallus arising from the disc. Erect thalli caespitose, simple or branched, hollow, yellowish brown to dark brown in color, up to 40 cm in height. Unilocular and plurilocular sporangia usually formed on separate thalli. Each cells contain a single parietal cup-shaped chloroplast without pyrenoid and a lot of physodes, exceptionally inner cells contain several discoidal chloroplasts. Plurilocular sporangia transformed from assimilatory filaments leaving 1-3 sterile terminal cells, uniseriate or biseriate. Unilocular sporangia formed from the basal part of assimilatory filaments, ovoid or ellipsoid, among assimilatory filaments. Widely distributed in the cold temperate water area of North Pacific Ocean. Abundant in intertidal zone. Nakahara (1984) showed isomorphic alternation of generations between unilocular sporangial plants and dioecious plurilocular sporangial plants. Unispores and plurispores pyriform, biflagellated with longer anterior flagellum containing a chloroplast with a stigma. Gametes (plurispores) are slightly anisogamous. Most of unfused gametes develop into haploid plants of its original sex or form unilocular and plurilocular sporangia together, however, meiosis does not occur in those unilocular sporangia. Zygote develop into diploid unilocular sporangial plant. Unispores, gametes and zygotes germinate forming emptied embryospore by migration of cellular contents migrate into germination tube, develop into compact disc. Erect thalli arise from the disc.

Comments: Hormosirene and ectocarpene are suggested to be actual sexual pheromones (Müller and others 1990). Nelson and De Wreede (1989) reported the dominance of plurilocular sporangial plants in western coast of North America, while both unilocular and plurilocular plants are common in Japanese coast.

Numbers of names and species: There are 4 species names in the database at present, of which 3 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.
