Abstract: Urocystis carcinodes (Berk. & Curt.) Fisch. v. Waldh. was found on Actaea spicala L. in northern Finland. The taxonomy and distribution of the fungus are discussed. Without infection experiments it is hardly possible to decide whether the smut on Cimicijuga (U. carcinodes s. str.) and the smut on Actaea, referred to U. ferrarisiana (Ciferri) Zundel, are different species.
