Nomenclatural notes
According to Art. 62 [Melbourne Code] compounds ending in "-botrys" are masculine - (15 Aug 2017) - M.D. Guiry

Description: Plants reach 6 cm in height, are erect from a discoid holdfast, and consist of irregularly branching cartilaginous, terete lower axes (to 1.5 cm in length) that expand distally into baloon-like terminal branches 3-6 mm in diam. The saccate axes are loosely filled with ganglionic cells with long anastomosing arms, the medulla being surrounded by a cortex of progressively smaller subisodiametric cells. Early carposporophyte details are lacking, but cystocarps are largely buried and consist of a central fusion cell surrounded by radiating gonimoblasts bearing terminal carposporangia, the pericarp pierced by an ostiole and having a filamentous inner hull. Spermatangia form in extensive surface sori, and tetrasporangia are scattered in the outer cortex.

Comments: Distribution: Endemic to southern California and Baja California, the plants being rare and usually restricted to deep habitats (to 100 m depths; Abbott and Hollenberg 1976).

Numbers of names and species: There is only one species or infraspecific name in the database at present, which 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.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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