The genus was first described by Danish botanist
Hans Christian Lyngbye in 1819,[2][3] and the type species is Callithamnion corymbosum(Smith) Lyngbye.,[2]
The genus of Callithamnion has undergone 2 major changes in its history.
Carl Nägeli (in 1861) transferred species without alternate branchlets to Antithamnion, Rhodochorton and Acrochaetium.[11] Then
Genevieve Feldmann-Mazoyer in 1941 created genus Aglaothamnion for species having uninucleate cells, zig-zag carpogonial branches and lobed groups of carposporangia, and re-circumscribed Callithamnion. Aglaothamnion is now sometimes regarded as a synonym of Callithamnion with insufficient evidence for separate evolutionary lines of development.[2]
Description
Callithamnion species are a marine red alga that is monaxial (having only one axis) with free
filaments and the
thalli are usually small tufts.[12]
They are also erect, up to 10 cm tall, with irregular branching and have multinucleate cells.[13]
In most species are
gametophytes and
sporophytes are found throughout the year, but are usually only fertile in the late summer and autumn.[8]
