Original publication and holotype designation: Kraft, G.T. & Saunders, G.W. (2014). Crebradomus and Dissimularia, new genera in the family Chondrymeniaceae (Gigartinales, Rhodophyta) from the central, southern and western Pacific Ocean. Phycologia 53(2): 146-166.
Taxonomic status: currently recognized as a distinct genus.
Description: Thalli bright to deep burgundy red; basally and marginally attached by discoid holdfasts; fronds prostrate, repent or erect on basalt or calcareous rock, frequently overlying hydrozoans, to 160 mm in lateral spread. Blades usually imbricate, not or only infrequently secondarily connected by haptera, often consisting of single or linear series of basally constricted opuntioid units 8-15 mm across in Lord Howe type material, the segments 15-25 mm across in Hawaiian populations; fronds 20-160 mm in lateral spread, lobes 8-15 mm broad, 80-200 µm thick. Reproductive structures in dactyloid marginal pods 450-800 µm wide, up to 2.5 mm long, the surfaces smooth or bearing varying numbers of branched, uniseriate filaments 100-150 lm in length by 6-8 µm in diameter, these arising singly or as densely aggregated extensions of extensive patches of surface cortical cells.

Numbers of names and species: There are 4 species names in the database at present, of which 4 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.

Verification of data
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
