Holotype species: Bryopsidella neglecta (Berthold) G.Furnari & M.Cormaci
Original publication and holotype designation: Rietema, H. (1975). Comparative investigations on the life-histories and reproduction of some species in the siphoneous green algal genera Bryopsis and Derbesia. pp. 1-130. Groningen: University of Groningen.
Precise date of publication21 Nov 1975
Taxonomic status: currently recognized as a distinct genus.
Most recent taxonomic treatment adopted: Furnari, G. & Cormaci, M. (2014). Nomenclatural observations on the genus Bryopsidella (Ulvophyceae, Bryopsidaceae). Phytotaxa 164(2): 159-160.
Furnari & Cormaci (2014: 159) note "It should be noted that Bryopsidella is generally attributed to Feldmann in Rietema [see Index Nominum Algarum and AlgaeBase (Guiry & Guiry 2014)], while Feldmann gave only the permission to Rietema to publish the Latin diagnosis of the genus. Therefore, the author of the genus is only Rietema (or Feldmann ex Rietema) and not Feldmann in Rietema." - (4 Apr 2014) - M.D. Guiry

Description: Coenocytic thalli of two forms roughly the same size, and small, siphonous, homoplastic, and lacking pyrenoids. Sporophytic thallus of branching, interwoven siphons at least sometimes anchored by rhizoids, suggestive of Derbesia; gametophytic thallus heterotrichous with branched prostrate siphons and unbranched erect ones, or else plumose; developed rhizoidal system of Bryopsis absent. Gametophytic and sporophytic thalli of one species previously were assigned to Bryopsis and Derbesia respectively. Sexual cycle involves alternation of distinct, heteromorphic diploid sporophytic and haploid gametophytic generations (diplohaplontic), that is, of the two thallus types described above, with meiosis occurring during sporogenesis. Stephanokontan zoospores are produced in lateral specialized sporangia separated from vegetative portions by plugs, or a "double septum" near their bases. They are released by gelatinization and rupture of encasing walls, and develop into monoecious or dioecious gametophytes. Anisogamous, biflagellated gametes, produced in essentially unspecialized gametangia separated from vegetative portions by basal plugs or cross walls, are released through one to many discharge papillae. Zygotes germinate about 24 hours after gametic fusion and eventually develop into characteristic sporophyte. Haploid chromosome number of N=8 reported for B. neglecta. Sporophytes also produce stellate propagules which reproduce sporophytic phase asexually.

Comments: Known geographic range is Mediterranean and Canary Islands. Bryopsidella grows on and possibly in fragments of dead coralline algae, and epiphytically on algae such as Halimeda, Peyssonnelia and Hypnea. Distribution probably more widespread
Numbers of names and species: There are 3 species names in the database at present, of which 2 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.

Verification of data
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.
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.
