In the water sample taken on September 7, 1976 from the pond in Głowno (Łódź District) filaments of Zygnema were found in vegetative stage. In culture a full development cycle of this alga was observed: vegetative filaments, conjugation, zygotes and their germination. The taxon was identified as Zygnema allorgei Gauthier-Lievre. Its diagnosis was supplemented. It is the second site of occurance of the species in the world. Z. allorgei was described for the first time in 1965 in Algeria
