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.

Taxonomic status: This name is of an entity that is currently accepted taxonomically.

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.

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."

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
