Nomenclatural notes
Substitute name for Capillaria Stackhouse 1809, nom. illeg.; not Capillaria Roussel 1806. - (23 Jan 2017) - M.D. Guiry

Description: Uniaxial, soft, branched one to four orders. Rhizoids cloaking relatively large axial cell, with four medially situated periaxial cells producing di- or trichotomously ramifying, determinate, corticating branches of rectangular to cuneate to ovate cells. Hairs present. Pit plugs lacking cap layers. Monoecious. Carpogonium borne on an adventitious branch. Terminal four cells of branch represent supporting cell and three-celled carpogonial branch. Auxiliary cell an enlarged cell of a branch borne on supporting cell. Fertilized carpogonium producing a connecting filament that contacts the auxiliary cell. A single gonimoblast initial producing a compact cystocarp, almost all cells becoming carposporangia, with no involucre. Spermatangia superficial. Tetrasporophyte heteromorphic, crustose, Cruoriopsis-like. Tetrasporangia small, cruciate, attached basally. Some populations with direct life history: gametophytes arising directly from crust produced from carpospore. Spore germination: usually a single rhizoid-like outgrowth, soon branching.

Numbers of names and species: There are 4 species names in the database at present, of which 3 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
