Editing Marimo (section)

==Classification and name==
Marimo were first described in the 1820s by [[Anton Eleutherius Sauter|Anton E. Sauter]], found in [[Lake Zell]], [[Austria]]. The genus ''Aegagropila'' was established by [[Friedrich Traugott Kützing|Friedrich T. Kützing]] (1843) with ''A. linnaei'' as the type species based on its formation of spherical aggregations, but all the ''Aegagropila'' species were transferred to subgenus ''Aegagropila'' of the genus ''Cladophora'' later by the same author (Kützing 1849). Subsequently, ''A. linnaei'' was placed in the genus ''Cladophora'' in the Cladophorales and was renamed ''Cladophora aegagropila'' (L.) Rabenhorst and ''Cl. sauteri'' (Nees ex Kütz.) Kütz. Extensive [[DNA]] research in 2002 returned the name to ''Aegagropila linnaei''. The presence of [[chitin]] in the cell walls makes it distinct from the genus ''[[Cladophora]]''.{{Cn|date=May 2021}}

The algae was named ''marimo'' by the Japanese [[Botany|botanist]] Takiya Kawakami in 1898. {{transliteration|ja|Mari}} is a type of bouncy play ball; {{transliteration|ja|mo}} is a generic Japanese term for plants that grow in water.

In Iceland the lake balls are called {{lang|is|kúluskítur}} by the local fishermen at [[Mývatn|Lake Mývatn]] ({{lang|is|kúla}} meaning 'ball', {{lang|is|skítur}} meaning 'muck') where the "muck" is any weeds that get entangled in their fishing nets. The generic name ''Aegagropila'' is Greek for 'goat hair'.{{citation needed|date=March 2020}}
