Holotype species: Crebradomus gongylocarpus G.T.Kraft & G.W.Saunders

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.

Description: Gigartinalean genus with densely clustered and semierect thalli; fronds overlapping, multiply attached by stout basal and interblade haptera; medulla filamentous, filaments mostly periclinal, occasionally anticlinal or oblique, without refractive, ganglionic or stellate cells; cortical filaments anticlinal, pseudodichotomous, three to five layered, the inner cells secondarily pit connected, the surface layer confluent. Carpogonial branches two to five celled, directed straight to the thallus surface, borne on intercalary supporting cells at several subcortical levels within irregularly contoured marginal swellings, the transition from blade to pod abrupt and the result of extensive palisade-like growth of cortical filaments; auxiliary cells apparently intercalary in the subsurface cortex; cystocarps densely aggregated, directed outwardly, subtended by ramified narrow elongate fusion cells, the distal unfused gonimoblasts forming ampulliform series of narrow cells, the filaments terminating in one- to three-celled single or short chains of carposporangia within a small ostiolate chamber. Spermatangial and tetrasporangial thalli not known.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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