Abstract
Spirogyra multiconjugata, a species of Zygnemataceae found in the Southern Province of Buenos Aires, Argentina, is proposed as a new species for science on the basis of the hitherto unreported occurrence of three types of conjugation in the same species: scalariform, lateral and terminal and on basis of the uniqueness of the features of its zygospores that were thoroughly analysed and described in acetolized material by both light and scanning electron microscopy. This species is the first bona fide species of the Punctata group reported for Argentina.
