Original publication: Lamouroux, J.V.F. (1813). Essai sur les genres de la famille des Thalassiophytes non articulées. Annales du Muséum d'Histoire Naturelle, Paris 20: 21-47, 115-139, 267-293, pls 7-13.
Description: Plants membranous, saccate, cylindrical to irregularly inflated, yellowish to medium brown, up to 1 m in length, polystichous by diffuse growth, attached on the substratum by a small disk, composed of inner layer consisting of large irregularly shaped large colorless cells and cortical layer consisting of smaller pigmented cells. Each cell contains several disc-shaped chloroplasts with prominent pyrenoids. Unilocular sporangia formed projected on the surface of the thallus in sori, accompanied by phaeophycean hairs and several celled paraphyses, obovoid. Unispores develop into fertile or sterile microthalli which directly form macroscopic thalli on them. Microthalli resemble Hecatonema and Ectocarpus in morphology (Kylin 1934, Pedersen 1984). Sexual reproduction unknown.

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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