Holotype species: Minium parvum R.L.Moe

Original publication and holotype designation: Moe, R.L. (1979). Minium parvum gen. et sp. nov., a crustose member of the Rhodymeniales (Rhodophyta). Phycologia 18: 38-46.

Taxonomic status: currently recognized as a distinct genus.

Description: Thallus a non-calcareous, solid crust; construction multiaxial, basal layer composed of pseudodichotomously branched prostrate filaments, giving rise to short erect filaments. Rhizoids and vesicular cells absent. Gametangial plants dioecious; spermatangial sori superficial and nemathecial. Procarpic, carpogonial branch 3-celled, auxiliary cell branch 2 celled, gonimoblast developing outwards from a small fusion cell. Cystocarps ostiolate, scattered, never coronate, protruding outwards, most cells forming carposporangia, tela arachnoidea absent. Tetrasporangia formed terminally from cortical filaments in nemathecia. Spores regularly cruciately arranged. Moe (1979) showed that Minium parvum has a 'Polysiphonia-type' life history in culture, although fertilization of female plants was not obtained.

Comments: Minium parvum grows epiphytically on articulated coralline algae at depths of 5-25 m, generally on exposed coasts. Known only from the Farallon Is. and Carmel Bay, California, and a few localities in British Columbia.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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