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: Thallus tough and leathery with a crustose base fully adherent to rock substratum. Rhizoids lacking. Horizontal filaments in crust giving rise to basal layer of downgrowing filaments composed of crowded isodiametric cells and to assurgent filaments of elongated cells separated by thick walls. Upper surface of crust and surfaces of erect axes covered by a thin cortex of isodiametric cells. Erect axes absent, unbranched, to dichotomizing several times. Branches terete, short and stout, or slender and to 15 cm. Elongated cells make up core of erect axes. Cells ca. 5 &m in diameter. Secondary pit connections common. Pit plugs with a cap membrane, but lacking an outer cap layer. Gametangia unknown. Tetrasporangia formed in pit-like conceptacles scattered over the surface of both erect and crustose portions of thallus. Tetrasporangia zonately divided, divisions parallel and transverse.

Comments: Hyphae of the fungus Mycosphaerella apophlaeae Kohlmeyer commonly present in walls and conceptacles, association possibly symbiotic. Two species known only from New Zealand and Subantarctic Islands. High intertidal.

Numbers of names and species: There are 2 species names in the database at present, as well as 1 infraspecific names. Of the species names, 2 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.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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