P. Thalictri. Te- leutospores, from Prof. Trail's On Thalictnott Jiavum, T. minus. Very rare; Kinloch Rannoch, Perthshire (Prof Trail); Kew Gardens. Autumn. (Fig. 1()3.) This species has all the marks of a perennial mycelium. The same plants are attacked by it year after year ; they are somewhat deformed and taller, with longer internodos, smaller and paler leaves and narrower segments. There is in Fischer a figure of a teleutospore with three cells, looking much like that of a Phragmidium. Cf. Puccinia fusca. Distribution North America. Northern and Central Europe, Siberia, 87.
