Notes
The formation of a closed ice cover was very retarded in autumn 1979 until December 27. In the open water was to be found a poor phytoplankton without any stratification. Only in three ponds a rich development had taken place. In the Eckteich the life-cycle of Mallomonas akrokomos Ruttner, heavily infested by Chytrids, could be observed; also M. parisae Bourrelly, for the first time with many cysts. Untwisted cells of Phacus similis Christen are discussed.
