Description: Life history diplohaplontic with alternation of large sporophyte bearing unilocular meiosporangia with paraphyses (sori) and microscopic dioecious and oogamous, heteromorphous gametophytes (for detail, see Laminaria). Sporophyte perennial (life-span unknown, at least 2 years), composed of holdfast, stipe and undivided blade. Meristematic region situated at transition region between stipe and blade. Holdfast with filamentous hapteres, stipe solid, cylindrical to compressed, smooth and up to 6.5 cm in length. Blade linear to lanceolate with plane median fascia, elevated to one surface; marginal portions covered with dense gyrate puckerings arranged pinnately along both sides of the median fascia. Sori develop on both sides of the blade. Mucilage ducts present in blade and stipe. Haploid chromosome number in K. crassifolia is n = 32 (Yabu and others 1985). In K. crassifolia growth is strongly seasonal (Kanda 1938-41, Yamamoto 1986). Structure of sporophyte as in Laminaria composed of photosynthetic meristoderm, parenchymatic cortex and central medulla. Genus endemic to the cold-temperate northwestern Pacific (Japan: Hokkaido and Kurile islands). Growing on rocks in the shallow subtidal together with Laminaria, Costaria, and Undaria.

Numbers of names and species: There are 2 species names in the database at present, of which 1 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.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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