Description: Plants reach 10 cm in length, are erect from a crustose base, and are flattened, irregularly branched, and marginally proliferous. Axes are multiaxial. The medulla is narrow and filamentous, and contains numerous rhizoids. Cystocarps are ostiolate and deeply embedded in the thallus, where they protrude mainly to one side. Carposporophytes consist of a central sterile tissue of subisodiametric cells giving rise peripherially to clusters of spore-bearing filaments interspersed with sterile filaments connecting to the pericarp, which lacks a distinct filamentous hull. Carposporangia form in rows. Similar to Anatheca and Meristotheca, Flahaultia differs from the former in producing chains of carposporangia, and from the latter in lacking a filamentous pericarp hull.

Most recent taxonomic treatment adopted: Schneider, C.W. & Wynne, M.J. (2007). A synoptic review of the classification of red algal genera a half a century after Kylin's "Die Gattungen der Rhodophyceen". Botanica Marina 50: 197-249.

Comments: Distribution: The type species comes from northwest Africa (Tangiers) and is not well known. Even less known is a second species, F. tegetiformans W. R. Taylor (1974), described on the basis of sterile material from 15-24 m depths from Jamaica.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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