title: Synchytrium solstitiale sp. nov. causing a false rust on Centaurea solstitialis in France.
abstract: A new species of Synchytrium, S. solstitiale, infecting leaves of Centaurea solstitialis in France, is described and illustrated. Synchytrium solstitiale causes development of orange to red galls on the leaves and petioles of living plants. It differs microscopically from all previously described species of the genus mainly in having larger sporangia and zoospores and resting spores that are formed in succession without an evanescent prosoral stage.
