Holotype species: Pseudocaulacanthus spinescens Huisman
Original publication and holotype designation: Huisman, J.M. (2018). Algae of Australia. Marine benthic algae of north-western Australia. 2. Red algae. pp. [i]-xii, 1-672, 189 figs. Canberra & Melbourne: ABRS & CSIRO Publishing.
Taxonomic status: currently recognized as a distinct genus.
Gender: This genus name is currently treated as masculine.
Most recent taxonomic treatment adopted: Schneider, C.W. & Wynne, M.J. (2019). Fourth addendum to the synoptic review of red algal genera. Botanica Marina 62(4): 355-367 [1-13].
Description: Thallus turf-like, with prostrate and erect terete axes. Prostrate axes attached to the substratum by clusters of multicellular rhizoids. Structure uniaxial; apical cell not obvious, but the central filament very prominent in section. Each cell of the central filament bearing 1 (rarely 2) periaxial filaments, these dichotomously branched and radiating outwardly and distally, eventually forming a filamentous cortex. Rhizoidal cells common, arising from medullary cells, forming linking filaments and secondary connections with other medullary filaments and producing a reticulum. Pseudoparenchyma absent. Tetrasporangia zonately divided arising in nemathecia on apices of erect axes.

Numbers of names and species: There is only one species or infraspecific name in the database at present, which has 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
