***Callithamnion*** is a genus of [algae](/source/Algae) belonging to the family [Callithamniaceae](/source/Callithamniaceae).[1]

The genus was first described by Danish botanist [Hans Christian Lyngbye](/source/Hans_Christian_Lyngbye) in 1819,[1][2] and the type species is *Callithamnion corymbosum* .,[1]

The genus has [cosmopolitan distribution](/source/Cosmopolitan_distribution).[3] Species are found in Europe (including Norway and Great Britain,[4]), Australia,[5] America (including Massachusetts, New York, North Carolina and Georgia),[6] [Newfoundland](/source/Newfoundland_(island)) (Canada),[7] [Sri Lanka](/source/Sri_Lanka) and South Africa.[8][9]

The genus of *Callithamnion* has undergone 2 major changes in its history. [Carl Nägeli](/source/Carl_N%C3%A4geli) (in 1861) transferred species without alternate branchlets to *[Antithamnion](/source/Antithamnion)*, *[Rhodochorton](/source/Rhodochorton)* and *[Acrochaetium](/source/Acrochaetium)*.[10] Then [Genevieve Feldmann-Mazoyer](/source/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.[1]

## Description

Callithamnion species are a marine red alga that is monaxial (having only one axis) with free [filaments](/source/Hypha) and the [thalli](/source/Thalli) are usually small tufts.[11] They are also erect, up to 10 cm tall, with irregular branching and have multinucleate cells.[12] In most species are [gametophytes](/source/Gametophytes) and [sporophytes](/source/Sporophytes) are found throughout the year, but are usually only fertile in the late summer and autumn.[7]
