Mougeotia ag. and Spirogyra Link (Zygnemaceae) - new species for the European flora

Abstract

In samples collected in Norway the following species new for Europe, Mougeotia olivacea Y.J. Ling, Mougeotia mysorensis Iyengar, Spirogyra reflexa Transeau and Spirogyra schmidtii W. et G.S. West, are identified. The diagnosis of M. olivacea has been supplemented with data on the dimensions of vegetative cells and zygotes and the number of pyrenoids. The diagnosis of M. mysorensis has been supplemented with data on the number and distribution of pyrenoids and, often curved, vegetative filaments. The sites of M. olivaceas and M. mysorensi's occurrence are the second one in the world. Morphological features and dimensions of S. reflexa and S. schmidtii are congruent with those given from other non-European sites.
