Taxonomic status: currently recognized as a distinct genus.

Gender: This genus name is currently treated as feminine.

Most recent taxonomic treatment adopted: Schneider, C.W., Popolizio, T.R., Kraft, L.G.K. & Saunders, G.W. (2019). New species of Galene and Howella gen. nov. (Halymeniaceae, Rhodophyta) from the mesophotic zone off Bermuda. Phycologia 58(6): 690-697.

Description: Plants erect and cartilaginous, consisting of single to clustered blades, with one or more blades arising from short stipes off discoidal or host-penetrating holdfasts, associated with sponges or epizoic on soft corals; erect axes simple to alternately or dichotomously to irregularly branched, flattened into narrow ligulate to slightly expanded blades, margins entire to dentate, and undulate to crenate and lacerated, with or without marginal proliferations, the axes often penetrating expanding blades with short proximal or percurrent midribs; blades structurally consisting of a cortex of one to several layers, the multiaxial medulla composed of dense anastomosing filaments between the cortical layers; reproductive structures borne in small, leaf-like proliferations arising from the blades or apically in wart-like clusters.

Numbers of names and species: There are 3 species names in the database at present, of which 3 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
