Abstract:
Sexual reproduction stages of fifteen desmid taxa were encountered in a tychoplankton sample from a shallow rain-forest pool in French Guiana. Zygospores are depicted for nine taxa. Those of Cosmarium dimaziforme (Grönbl.) A.M. Scott et Grönbl., Euastrum ciastonii var. apertisinuatum Scott et Prescott, Groenbladia bourrellyi stat. et nom. nov. (synonymous to Hyalotheca neglecta var. major Taylor), Staurastrum eskolense nom. nov. et stat. nov. (synonymous to S. elegantissimum var. brasiliense Förster) and Xanthidium trilobum Nordst. are new to science. The phenomenon of simultaneous conjugation by a number of different desmid taxa, also known from literature, might be explained by the production of non-species-specific pheromones inducing mating activity in a number of related algal species.
