Holotype species: Neogoniolithon fosliei (Heydrich) Setchell & L.R.Mason

Currently accepted name for the type species: Neogoniolithon brassica-florida (Harvey) Setchell & L.R.Mason

Original publication and holotype designation: Setchell, W.A. & Mason, L.R. (1943). Goniolithon and Neogoniolithon: two genera of crustaceous coralline algae. Proceedings of the National Academy of Science of the United States of America 29: 87-92.

Taxonomic status: currently recognized as a distinct genus.

Most recent taxonomic treatment adopted: Athanasiadis, A. (2016). Phycologia Europaea Rhodophyta Vol. I. pp. [i]-xxxxviii, 1-762. Thessaloniki: Published and distributed by the author.

Description: Thalli comprising dorsiventral crusts sometimes roughened by protuberances; attached, or unattached and consisting of masses of protuberances. Haustoria lacking. Organized into one order of vegetative filaments (monomerous); the lowermost filaments in crusts arranged in decumbent arching tiers of cells (coaxial anatomy), cells in the protuberances not in arching tiers. Each vegetative filament containing a terminal or subterminal meristematic cell which can divide to produce epithallial cells outwardly and vegetative cells inwardly. Stratified elongate cells (palisade cells) lacking. Outermost walls of epithallial cells rounded or flattened, not flared. Cells in contiguous filaments often joined by fusions; secondary pit-connections lacking. Trichocytes sometimes present, occurring singly, in horizontal strata, or vertical series; either terminating filaments at the thallus surface or intercalary and buried below the surface. Reproductive cells forming within uniporate conceptacles. Tetrasporangial and bisporangial conceptacles with or without central columella; apical sporangial plugs absent. Gametangia poorly known.

Comments: Comments about the distribution and other facets of the biology of Neogoniolithon are almost meaningless in view of the uncertainty that exists in specimen identification. Possibly this genus is primarily tropical and subtropical. Neogoniolithon resembles Spongites more than it resembles other genera. However, the former has arching tiers of cells in crustose portions; Spongites does not.

Numbers of names and species: There are 64 species names in the database at present, as well as 12 infraspecific names. Of the species names, 42 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.

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.
