Neurocaulonex Kützing, 1849, nom. et typ. cons.
Holotype species: Neurocaulon foliosum (Meneghini) Zanardini ex Kützing
Original publication and holotype designation: Kützing, F.T. (1849). Species algarum. pp. [i]-vi, -922. Lipsiae [Leipzig]: F.A. Brockhaus.
Taxonomic status: currently recognized as a distinct genus.
Gender: This genus name is currently treated as neuter.
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.
The type has been conserved. Silva (1994: 260) notes: This name was first definitely accepted by Kützing (1849: 744), but is illegitimate because it was applied to a genus that subsumed Constantinea Postels & Rupr. 1840. Because a type was not indicated, Neurocaulon must be typified with N. rosa-marina (S. G. Gmel.) Kiitz. (Fucus rosa-marina S. G. Gmel.), the designated type of Constantinea. Taxonomically, however, two distinct genera are involved. Conservation of Neurocaulon with N. foliosum (Menegh.) Zanardini ex Kütz. as conserved type fixes the application of the generic name in its present sense." This proposal was accepted. - (23 Jan 2017) - M.D. Guiry
Description: Plants reach 12 cm in length, are erect from a discoid holdfast, terete and cartilaginous below, and proliferous above with simple and very distinctive reniform blades. Carpogonial branches and auxiliary cells are similar to those of Halarachnion. Tetrasporangia are produced in diminutive crusts from which erect gametophytes also arise. Anatomical and life history studies have been made by Codomier (1967, 1969).

Comments: Distribution: The type and the second species, H. grandifolium Rodriguez, are endemic to the Mediterranean Sea.
Numbers of names and species: There are 7 species names in the database at present, of which 3 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.

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.
