Celakovsky (1874) had recognized three generations in the life cycle of Coleochaete: zoospore-producing thalli (A); gamete-producing thalli (B); and the multicellular body produced from the fertilized oospore (C).
The latter two species are heterothallic thus did not produce oospores and or sexual structures in single cultures.
According to macrofossil data, the number of Chara oospores and Potamogeton seeds decreased significantly in comparison with the previous zone.
