Reticulobotrys E.Y.Dawson, 1949

Holotype species: Reticulobotrys catalinae E.Y.Dawson

Original publication and holotype designation: Dawson, E.Y. (1949). Contributions toward a marine flora of the southern California Channel Islands. I-III. Occasional Papers of the Allan Hancock Foundation 8: 1-57, 15 plates.

Precise date of publication: 15 Aug 1949

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.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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