Description: Plants of the largest species reach 30 cm in length. Thalli are erect from a crustose base, linear, flattened, and more-or-less dichotomously branched, with greater or lesser numbers of marginal proliferations. The medulla is a broadly filamentous mix of primary and rhizoidal filaments, and the cortex is composed of isodiametric cells of progressively decreasing size. Supporting cells are initially located in the subsurface layer and have an initially horizontal trichogyne that bends sharply outwards. Carposporophytes do not have a consolidated basal fusion cell, but have downwardly growing fusion processes that extend from the lower gonimoblast layers and penetrate deep into the gametophytic tissue. Cystocarps are scattered across the blades or confined to the margins. The type species is monoecious, the spermatangia occurring singly or in 2-3's on surface mother cells scattered over wide areas of the blade.

Taxonomic status: This name is of an entity that is currently accepted taxonomically.

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: Papenfuss and Edelstein (1974) treat Carpococcus as a synonym of Sarcodia, although the type species, C. gattyae J. Agardh, has not been formally transferred or synonymized with any Sarcodia species. Distribution: The type and 2 additional species are from New Zealand. The group is concentrated in the southern hemisphere, with representatives from Australia (2), Lord Howe Island (1), Mauritius (2), Sri Lanka (2), and South Africa (1). 2-3 species are recorded from southern Japan, Taiwan the Philippines and Dakar in the northern hemisphere.

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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