Taxonomic status: currently recognized as a distinct genus.
Gender: This genus name is currently treated as masculine.

Description: Plants form small lobed cushions on rhodomelaceous hosts. Gametophytes are dioecious, and spermatangia develop in clusters from superficial cortical cells. Carpogonial branches are 4-celled; cystocarps are aggregated, embedded, and surrounded by a porate hull of sterile gametophytic filaments. Carposporangia form in terminal pairs. Goff and Coleman (1985) have followed the progress of secondary pit connection formation and hypothesize that parasite nuclei transferred to host cells by conjunctor cells may control and redirect the host physiology for benefit of the parasite.

Comments: Distribution: The type species occurs on Polysiphonia and related genera along the northern rim of the Atlantic from Connecticut in the west to Spain in the east, and in the eastern Pacific from Alaska to Baja California. A reputed second species, C. odonthaliae Levring, was shown to be equivalent to Harveyella mirabilis (below) by Edelstein and McLachlan (1977).
Numbers of names and species: There are 15 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
