Original publication and holotype designation: Zanardini, G. (1843). Saggio di classificazione naturale delle Ficee del Dottore Giovanni Zanardini aggiunti nuovi studii sopra l'androsace degli antichi con tavola miniata ed enumerazione di tutte le specie scoperte e raccolte dall'autore in Dalmazia. pp. -64, 2 folded tables, 1 col. pl. Venezia [Venice]: Dallo Stabilimento tipographico enciclopedico di Girolamo Tasso.
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.
Monotypic when first introduced. - (24 Jan 2017) - M.D. Guiry
Description: Plants are creeping, dorsiventral, alternately branched, epiphytic, and anchored on the underside by rhizoids. Fronds reach 1 cm in lateral extent and are pseudoparenchymatous throughout, with large, isodiametric, secondarily linked medullary cells giving rise peripherally to progressively smaller cortical cells. Spermatangia and cystocarps are known in only one of the 4 speciesi spermatangia are in small flat sori, whereas carpogonial branches occur in median, linear sori. Tetrasporangial sori lack paraphyses, the tetrasporangia being either zonate or irregularly cruciate depending on the species (Denizot 1968).

Comments: Distribution: The type and a second species, C. squamariae (Meneghini) Denizot, are endemic to the Mediterranean Sea, where they occur subtidally on sponges and other, often encrusting algae. Two other little-known species are recorded from Easter Island and Japan.
Numbers of names and species: There are 10 species names in the database at present, of which 5 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.
