Callithamnion is a genus of algae belonging to the family Callithamniaceae.[2]

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 has cosmopolitan distribution.[4] Species are found in Europe (including Norway and Great Britain,[5]), Australia,[6] America (including Massachusetts, New York, North Carolina and Georgia),[7] Newfoundland (Canada),[8] Sri Lanka and South Africa.[9][10]

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[edit]

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]
