Bossiella P.C., 1957
Holotype species: Bossiella plumosa (Manza) P.C.Silva
Original publication and holotype designation: Silva, P.C. (1957). Notes on Pacific marine algae. Madroño 14: 41-51.
Taxonomic status: currently recognized as a distinct genus.
Woelkerling et al. (2008) consider that Bossiella should be removed from the floras of Japan, Korea and China. - (25 Aug 2010) - Wendy Guiry
Description: Thalli comprising crustose holdfasts bearing one to several erect, variously branched, articulated fronds. Fronds of calcified intergenicula separated by uncalcified genicula. Intergenicula compassed to flattened. Anatomically, intergenicula of arching tiers of medullary cells surrounded by a photosynthetic cortex and a unistratose layer of epithallial cells. Cells in contiguous filaments often fusing; secondary pit-connections lacking. Genicula consisting of single tiers of long, straight, unbranched cells uncalcified except where they project into neighboring intergenicula. Trichocytes presumably present, but unknown. Reproductive cells forming within conceptacles originating from primordia in intergenicular cortex (lateral conceptacles). At maturity, one to numerous conceptacles with central or excentric pores protruding from intergenicular surfaces. Conceptacles lacking surmounting branches. Tetrasporangial or bisporangial conceptacles containing >30 mature sporangia prior to spore discharge. Sexual plants dioecious. Pores of spermatangial conceptacles opening at tip of short beak. Carpogonial conceptacles with extensive layer of supporting cells with carpogonial filaments. Carposporangial conceptacles containing broad, thin fusion cells with gonimoblast filaments arising from upper surface. Spores germinating into crustose sporelings by the Corallina-type of spore germination. Subsequent growth is into a slowly spreading crust from which fronds develop. Bossiella is characterized by conceptacles that are solely lateral. Branching various, some species pinnate, others dichotomous, others irregular, others with some combination of these patterns. One species (B. schmittii) is strongly dorsiventral in habit. Reproduction resembles that in Corallina except for the lateral position of conceptacles and the presence of gonimoblast filaments on the entire upper surface of the fusion cell. In addition some species rely almost entirely on bispores for dispersal. Fertile intergenicula in B. schmittii may bear as many as 50 conceptacles on the upper surface.

Comments: The species in Bossiella occur in southern South America (Chile and Argentina) and in North America from Alaska to Baja California Sud, Mexico.
Numbers of names and species: There are 25 species names in the database at present, as well as 3 infraspecific names. Of the species names, 16 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

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.
