Description: Thallus erect, epiphytic or epilithic, to 25 cm high, cylindrical axis irregularly and richly branched. Medulla single-stranded, the central filament, which is terminated by an assimilatory filament, is surrounded by downwardgrowing hyphae that in older thallus parts together form a firm syntagmatic medulla. Meristematic region of leading filament among youngest laterals. Sharp border between medulla and cortical layer, which is composed of cylindrical, straight assimilatory filaments, phaeophycean hairs, and ovoid to pyriform unilocular sporangia. Plurilocular sporangia unknown. Life history not studied. Distributed on temperate coasts of the North Atlantic Ocean.

Numbers of names and species: There are 10 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
