Original publication and holotype designation: Kraft, G.T. (1973). The morphology of Cubiculosporum koronicarpis gen. et sp. nov., representing a new family in the Gigartinales (Rhodophyta). American Journal of Botany 60: 872-882.
Taxonomic status: currently recognized as a distinct genus.
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.
Description: A family of a single genus and species. Plants are multiaxial. All but the surface cells are multinucleate, and inner cortical cells are linked by secondary pit connections. Female thalli are non-procarpic. A single short connecting filament links the carpogonium with the auxiliary cell, which is an undifferentiated intercalary cell in a vegetative cortical filament. Gonimoblast initials are multiple and gonimoblast filaments are diffuse, at first directed from the auxiliary cell toward the thallus center. The mature cystocarp is a mixture of gonimoblast filaments growing between and partially fused to gametophytic medullary cells. Carposporangia are single or in short chains on peripheral gonimoblast cells, released through an ostiole. Spermatangia are formed in isolated patches on outer cortical mother cells. Tetrasporophytes are isomorphic with gametophytes, the tetrasporangia zonate and terminal. Cubiculosporum plants reach 6 cm in height and are erect from a discoid base, with secondary attachments produced by lower lateral branches. They are cartilaginous in texture, with several orders of pinnate branching arising from the margins of compressed axes. Axes are composed of a filamentous medulla and pseudoparenchymatous cortex of isodiametric cells. Carpogonial branches are 3-celled and directed toward the thallus surface. Mature carposporangia are produced in chambers formed by the enlargement of the fertile pinnule and the elongation of cells in 2-3 layers of the outer medulla. Spermatia are formed as clusters of mother cells borne radially around basal cells separated by paraphyses of elongate sterile cortical cells.

Numbers of names and species: There is only one species or infraspecific name in the database at present, which has 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.
