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.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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