Boodleopsis A.& E.S. , 1911
Holotype species: Boodleopsis siphonacea A.Gepp & E.S.Gepp
Original publication and holotype designation: Gepp, A. & Gepp, E.S. (1911). The Codiaceae of the Siboga Expedition including a monograph of Flabellarieae and Udoteae Siboga-Expeditie Monographie LXII. pp. 1-150, 22 pls. Leiden: E.J. Brill.
Taxonomic status: currently recognized as a distinct genus.
Description: Thallus small, generally forming cushions or turfs of creeping, unbranched, interwoven siphons and creeping or semi-erect branches anchored by scattered rhizoids. Siphons coenocytic in young thalli, but in older thalli irregular cross walls reported for some species, so that further observations are required. Genus probably heteroplastic; pyrenoids absent. Two types of spherical to subspherical zooidangia are known for some species; zooidangia are not grouped into separate reproductive structures as in Halimeda. Large zooidangia, to 250 µm diam., produce stephanokontan swarmers; smaller ones, to about 150 µm diam., give rise to biflagellated swarmers (presumed gametes) which may differ slightly in size, contain 1 to a few plastids accordingly, and lack a stigma. Both kinds of zooidangia may occur on same thallus. Non holocarpic; swarmers (both kinds) released through preformed abscission zone of discharge tubes which develop near zooidangia; in some species plugs or walls isolating zooidangia and their discharge tubes from remainder of thallus develop during discharge. In culture, stephanokont zooids, after settling, can produce germination tube in about 2 days; branching develops 1-2 weeks later, semi-erect branches with dichotomies occur in 3-4 weeks, and mature thalli in at least 6 months. Development of zygotes or other stages from biflagellated zooids have yet to be observed. Vegetative reproduction may occur by regeneration of released protoplasts.

Comments: Geographic range tropical to subtropical; reported from West Africa, Bermuda, western Caribbean, east, mid and western Pacific including Indonesian reefs. Boodleopsis forms green cushions and mats on supralittoral to midlittoral rocks, mud, mangrove roots, and on muddy bottoms of shallow bays, often in relatively sheltered and shaded, as well as euryhaline sites. Associated algae include Bostrychia, Cladophora, Caloglossa and Dichotomosiphon. Some writers have suggested that some or all species represent an alternate life cycle stage of other bryopsidalean algae.
Numbers of names and species: There are 9 species names in the database at present, of which 9 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.

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.
