|Description||English: These "jelly balls" are colonies of the cyanobacteria species Nostoc pruniforme ("Mare's eggs"), living in freshwater ponds. (Determination was microscopically confirmed by Professor Dr Ludwig Kies, Hamburg.)
Note: Many other single-celled organisms also form gelatinous colonies in spherules. A reliable determination is only possible by microscope! The shown species is rather rare today and indicates clean water. Furthermore, my impression is that the trivial name "Mare's eggs" is not exclusively related to the concrete species Nostoc pruniforme, but also used for diverse different spherule algae (?).
Deutsch: Teichpflaumen, Nostoc pruniforme – bei diesen gallertigen Kugeln handelt es sich um Kolonien bestimmter Süßwasser-Cyanobakterien (oder: "Blaualgen"). Vielen Dank an Prof. Dr. Ludwig Kies, Hamburg, für die mikroskopische Nachbestimmung!Beachte: Sehr viele andere ein-/wenigzellige Organismen formen ebenfalls gallertige Kolonien in Kugelform. Eine sichere Bestimmung ist normalerweise nur per Mikroskop möglich! Die hier gezeigte Art ist heutzutage recht selten zu finden.
