Callithamnion Explained
Callithamnion is a genus of algae belonging to the family Callithamniaceae.[1]
The genus was first described by Danish botanist Hans Christian Lyngbye in 1819,[2] and the type species is Callithamnion corymbosum .,
The genus has 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), Newfoundland (Canada),[6] Sri Lanka and South Africa.[7] [8]
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.[9] 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.
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.[10] They are also erect, up to 10 cm tall, with irregular branching and have multinucleate cells.[11] In most species are gametophytes and sporophytes are found throughout the year, but are usually only fertile in the late summer and autumn.[6]
