Description: The Blinksiaceae is a monospecific family in which plants are non calcified crusts attached without rhizoids to intertidal rocks. Crusts are composed of a thin hypothallus of irregularly arranged cells and a regularly ordered perithallus of erect, firmly aggregated filaments. Tetrasporangia are zonate and terminal on perithallial filaments in nemathecioid groups, and are separated by multicellular paraphyses. Carpogonial branches are 4-celled and terminal on short, erect filaments. Plants are non-procarpic. Auxiliary cells are distal and intercalary in perithallial filaments, and are diploidized by short connecting filaments issued by fertilized carpogonia. Gonimoblasts are compact, globular, directed outwardly, and composed almost entirely of subspherical carposporangia. Spermatangia are unknown. The Blinksiaceae is a group with strong anatomical similarities to the Cruoriaceae, but in which the carposporo phytes develop outwardly from auxiliary cells as opposed to either inwardly or outwardly from sites on the connecting filaments themselves. As this is a feature that occurs both ways in the Calosiphoniaceae, the independance of the Blinksiaceae from the Cruoriaceae should perhaps be reconsidered. Blinksia has the characteristics of the family. Crusts are irregularly circular and reach 2-5 mm in diameter.

Comments: Distribution: Known only from intertidal rocks at the type locality on the Monterey Peninsula of central California.
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

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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