Callithamnion Collabens
''Callithamnion'' is a genus of algae belonging to the family Callithamniaceae. The genus was first described by Danish botanist Hans Christian Lyngbye in 1819, and the type species is ''Callithamnion corymbosum'' ., The genus has cosmopolitan distribution. Species are found in Europe (including Norway and Great Britain,), Australia, America (including Massachusetts, New York, North Carolina and Georgia), Newfoundland (Canada), Sri Lanka and South Africa. 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''.Carl Nägeli, 1861, Beiträge zur Morphologie und Systematik des Ceramiaceae. Sber. bayer. Akad. Wiss. Jb. 1861, Vol. 1, pp. 297–415, Plate 1. Then Genevieve Feldmann-Mazoyer in 1941 created genus ''Aglaothamnion'' for species having uninucleate cells, zig-zag carpogonial branches and lobed groups of carposporangia, ...

Algae
Algae ( , ; : alga ) is an informal term for any organisms of a large and diverse group of photosynthesis, photosynthetic organisms that are not plants, and includes species from multiple distinct clades. Such organisms range from unicellular microalgae, such as cyanobacteria, ''Chlorella'', and diatoms, to multicellular macroalgae such as kelp or brown algae which may grow up to in length. Most algae are aquatic organisms and lack many of the distinct cell and tissue types, such as stomata, xylem, and phloem that are found in embryophyte, land plants. The largest and most complex marine algae are called seaweeds. In contrast, the most complex freshwater forms are the Charophyta, a Division (taxonomy), division of green algae which includes, for example, ''Spirogyra'' and stoneworts. Algae that are carried passively by water are plankton, specifically phytoplankton. Algae constitute a Polyphyly, polyphyletic group because they do not include a common ancestor, and although Eu ...
