Neopolyporolithon W.H.Adey & H.W., 1972
Holotype species: Neopolyporolithon reclinatum (Foslie) W.H.Adey & H.W.Johansen
Currently accepted name for the type species: Neopolyporolithon reclinatum (Foslie) W.H.Adey & H.W.Johansen
Original publication and holotype designation: Adey, W.H. & Johansen, H.W. (1972). Morphology and taxonomy of Corallinaceae with special reference to Clathromorphum, Mesophyllum, and Neopolyporolithon gen. nov. (Rhodophyceae, Cryptonemiales). Phycologia 11: 159-180, 69 figs, 1 table.
Precise date of publication23 June 1972 (stated on back outside cover of journal issue). The requirements for valid publication are specified in the ICBN (International Code of Botanical Nomenclature).
Taxonomic status: currently recognized as a distinct genus.
Most recent taxonomic treatment adopted: Adey, W.H., Hernández-Kantún, J.J., Johnson, G. & Gabrielson, P.W. (2015). DNA sequencing, anatomy, and calcification patterns support a monophyletic, subarctic, carbonate reef-forming Clathromorphum (Hapalidiaceae, Corallinales, Rhodophyta). Journal of Phycology 51(1): 189-203.
The ICBN rules cited below are those adopted by the Seventeenth International Botanical Congress, Vienna, Austria, July 2005 (McNeill et al. 2006).
In accordance with ICBN Art 13.3, the name Neopolyporolithon is treated as pertaining to a non-fossil taxon because its type is based on a non-fossil specimen. No species based on fossil types have been assigned to the genus.
The generic name Neopolyporolithon is typified (ICBN Art 10.1) by the type of N. reclinatum, the only species originally included in the genus. - (26 Aug 2009) - M.D. Guiry
Description: Thalli encrusting or epiphytic; multifilament hypothallium of ascending and descending filaments, parallel to substratum; strong tendency to be "leafy" in habit; epithallium 1-7 cell layers, minimally photosynthetic; meristem intercalary below epithallium, photosynthetic; growth (cell division and elongation) occurring only in meristematic cells before formation of transverse cell walls, but not in a strongly defined band (no meristem split); double mode of calcification absent; all conceptacle primordia developed directly from intercalary meristem, sunken at maturity; sporangia bearing columnar cap walls (i.e., conceptacles multiporate), roof exposed by sloughing-off overlying epithelium; conceptacle cavity calcite, including surrounding and underlying perithallium dissolved by maturing sporangia; roof of spermatangial conceptacles not reformed by lateral growing in of tissue; spermatangia produced from columnar cells clothing entire inner wall of conceptacles.

Comments: The correct application of the name was established by sequencing the holotype specimen (TRH, B17-2590) of the generitype species.
Numbers of names and species: There are 3 species names in the database at present, of which 2 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.

Verification of data
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.
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.
