Description: Thallus forming hemispherical, parasitic cushions 0.5-1.0 mm in diameter on the hollow fronds of Halosaccion. With increasing age the parasite extends into the central cavity of the host, although initial infections of the inner wall of the host also occur. Cushions and enclosed in a common gelatinous envelope, and composed of irregularly branched filaments in 3-5 rows, forming protoplasmic connections with the host cells. Spermatangia formed subterminally in pairs from a spermatangial mother cell; carpogonia and cystocarps unknown. Life history unknown, although probably similar to that of other members of the Palmariaceae. Tetrasporangia formed terminally on erect filaments, regenerating repeatedly from a well-defined stalk cell; well-defined paraphyses forming between the tetrasporangia. Spores regularly cruciately arranged.

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

Gender: This genus name is currently treated as masculine.

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: Known only from a single collection of Halosaccion minjaii I.K. Lee from Massacre Bay, Attu Island, Aleutian Islands, Alaska, this genus is superficially similar to Halosacciocolax which parasitises Palmaria and Devaleraea species, but which has never been reported from Halosaccion species. Neohalosacciocolax mainly differs fromHalosacciocolax in the formation of clearly defined generative stalk cells in the tetrasporangia and in the development of paraphyses between the sporangia. The mode of formation of spermatangia is very different to that described for Halosacciocolax by Lund (1959), but this requires further investigation.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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