Description: Thallus erect, occasionally decumbent, arising from a discoid stoloniferous or rhizomatous prostrate system. Axes terete (in N.W.A.); branching alternate, irregular or spiral, all branches with short spirally arranged spines; apices projecting or in shallow pits, with a few branched trichoblasts. Structure uniaxial, with 5 pericentral cells per segment, surrounded by a pseudoparenchymatous medulla and cortex. Spermatangia on stalked plate-like trichoblasts. Cystocarps sessile, each subtended by spine-like branchlets. Tetrasporangia in short lateral spinose branchlets (becoming stichidial in some species), several per segment.

Comments: The spines on the surface of Acanthophora thalli originate on the abaxial side of a basal cell of a trichoblast according to Kraft (1979). Gordon-Mills and Womersley (1987), however, pointed out that the spine "appears to develop directly from the whole trichoblast which is highly modified. In this case the spines are directly comparable to the pointed spurs at the base of the cystocarp of Chondria spp. that also develop from the modified fertile trichoblast."

Numbers of names and species: There are 18 species names in the database at present, as well as 8 infraspecific names. Of the species names, 7 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
