Nomenclatural notes
Conserved against Apiarium Durant, 1850 (type: A. apiculata Durant). Based on Delesseria subgen. Caloglossa Harvey (1853: 98) "SUB-GENUS 4. CALOGLOSSA, Harv.; Frond dichotomous, articulate-constricted, rooting at the forks, livid purple.". This subgenus contained only one species, Delesseria Leprieurii Mont. which automatically typifies the genus name. J.Agardh (1852: 680, 682) also employed the name as a subgenus or section with a question mark, but did not credit it to Harvey as intimated by Athanasiadis (2016: 1083). - (25 Jan 2017) - M.D. Guiry

Description: Thallus prostrate, membranous, regularly subdichotomously branched. Axes slightly to markedly constricted at the nodes, attached by rhizoids arising from the midrib at the nodes; adventitious branches common, arising from the midrib. Structure uniaxial, with a prominent midrib and lateral blades 1 cell thick, growth leading by exogenous branching pattern, in which each apical cell cuts off two oblique subapical cells before cutting off lateral pericentral cells; lateral veins absent; only some cells of second-order cell rows producing third-order rows; apical cells of all cell rows reaching the margin of the thallus; intercalary divisions absent. Spermatangia in sori on terminal and subterminal segments, on both surfaces of the blade, covering the whole of the blade with the exception of the marginal cells, some lateral cells and all transverse pericentral cells. Procarps and cystocarps sessile, forming on the midrib. Tetrasporangia in sori on alae on both sides of the midrib, forming in series on the adaxial surface of secondary cell rows, the bearing cell producing cover cells transversely, tetrahedrally divided [after Schneider & Searles (1991: 405–406); King & Puttock (1994)].

Numbers of names and species: There are 25 species names in the database at present, as well as 13 infraspecific names. Of the species names, 19 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.

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.
