Substitute name for Carmichaelia Greville 1827, non R.Brown 1825. - (29 Aug 2011) - M.D. Guiry
Description: Plants tubular, polystichous, hollow, repeatedly oppositely branched, attenuated toward the apex terminated with phaeophycean hairs, up to 50 cm in height, yellowish to medium brown in color, composed of colorless large inner cells and single layer of pigmented peripheral cells. Terminal part of thallus often uniseriate. Phaeophycean hairs scattered or formed in whorls. Unilocular sporangia formed from the peripheral cells, often in sori, sessile, ovate or ellipsoidal, associated with a paraphyses-like elongated peripheral cells. Each cell contains many disc-shaped chloroplasts with pyrenoids. Unispores as well as plurispores normally flagellated, containing a chloroplast with a stigma. Plurilocular sporangia not known on erect thalli. Although various culture results reported by various authors, recent reports suggest monophasic, heteromorphic type of life history (Nygren 1975, Pedersen 1984). Unispores developed into filamentous microthalli forming ectocarpoid plurilocular sporangia or unilocular sporangia whose swarmers reproduced erect thalli or microthalli. Usually subtidal, spring to summer annual, epilithic or epiphytic. Distributed in temperate water area of Pacific, Atlantic Ocean and Mediterranean Sea.

Numbers of names and species: There are 3 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
