Description: Upright, up to 20 cm tall, cylindrical, polysiphonous thalli from a discoidal holdfast; many branches, both determinate and indeterminate, spirally oriented; branches formed exogenously or adventitiously, the latter sometimes in axils of other branchlets. 6 pericentral cells (sometimes 5), each dividing transversely, the distal cell retaining pit connection with axial cell; each pericentral cell product having anticlinal and periclinal divisions. Both determinate and indeterminate branches dorsiventrally oriented in having deciduous pigmented trichoblasts only on abaxial side, in 2 zig-zag rows (in the type species); in other species (N. larix) trichoblasts on indeterminate branches are arranged in a spiral on the axis but in 2 rows on determinate branchlets. Germlings bipolar, erect system with dorsiventral orientation, trichoblasts zig-zag in two rows on dorsal side, germling curved ventrally. Gametophytic reproductive structures replacing trichoblasts on determinate laterals. Male capitula cylindrical, without a sterile tip. Procarp on suprabasal polysiphonous segment, comprised of 4-celled carpogonial branch and 2 sterile cell groups attached to the supporting cell; cystocarps ovoid to spheroid, ostiolate, often almost sessile on branchlet. Tetrasporangia in unmodified determinate curved vegetative branchlets, 2 per segment.

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

Gender: This genus name is currently treated as feminine.

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: Intertidal, temperate North Pacific. Similar to Rhodomela but separated by the dorsiventral orientation of trichoblasts on some branches in Neorhodomela, those of Rhodomela always being spirally arranged on axes.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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