Holotype species: Rhodenigma contortum J.A.West, Verbruggen & Loiseaux-de Goër

Original publication and holotype designation: West, J.A., Zuccarello, G.C., Loiseaux de Goër, S., Stavrias, L.A. & Verbruggen. H. (2016). Rhodenigma contortum, an obscure new genus and species of Rhodogorgonales (Rhodophyta) from Western Australia. Journal of Phycology 52(3): 397-403, 3 figs.

Description: In laboratory culture this small red alga forms unattached uniseriate branched filaments, either in unattached aggregate clumps or attached to glass, producing compact crusts with conspicuous vein-like, narrow filaments and laterals, many short-celled branches filling open free space and becoming tightly coherent between main filaments. Cells have a single narrow or variously shaped peripheral red chloroplast without pyrenoids. Apical and subapical cells are usually a very pale pink color, often becoming contorted and digitate, either attaching to glass or to other adjacent filaments forming nodules. Pit connections are visible under the compound microscope. No sporic reproduction was observed. In culture, the alga attached to glass but not to bleached coral fragments.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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