Nomenclatural notes
Lectotype selected by Kylin (1956: 383). - (24 Jan 2017) - M.D. Guiry

Description: Thallus erect to l0 cm high, axes monosiphonous, irregularly branched, with or without rhizoidal cortication, and bearing alternately-placed, branched or unbranched determinate branchlets singly from each cell of the mature axis. Cells multinucleate. Chromosomes 0.3-1.5& long; haploid number 28-33 in most species. Procarps and carposporophytes at intervals of several cells near branch apices. Carpogonial branch 4-celled borne on first formed of pair of opposite pericentral cells with carpogonium lying between 2 auxiliary cells cut off respectively from pericentral cells. Fusion between carpogonium and auxiliary cells by means of connecting cells. Carposporophytes bearing successive groups of carposporangia. Spermatangial clusters and tetrahedrally-divided tetrasporangia borne on cells of determinate branchlets. Common and widespread in most habitats. In culture presence of terminal hairs and density of axial cortication appear to increase in rougher water conditions. Sporangial types (mono-, bi-, poly-) inconsistent lacking taxonomic significance. Range of plant form causing confusion in species delimitation.

Comments: Concept of genus Callithamnion has undergone 2 major changes (a) Nägeli (1861) transferred species without alternate branchlets to Antithamnion, Rhodochorton and Acrochaetium, (b) Feldmann-Mazoyer (1941) erected Aglaothamnion for species having uninucleate cells, zig-zag carpogonial branches and lobed groups of carposporangia, and recircumscribed Callithamnion. Aglaothamnion now sometimes regarded as synonym of Callithamnion with insufficient evidence for separate evolutionary lines of development.

Numbers of names and species: There are 378 species names in the database at present, of which 83 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.
