| Abstract: | Uredinial and telial states of aMelampsora species occurring on the leaves ofSalix serissaefolia were for the first time recorded. Field observations and inoculation experiments showed that the spermogonial and aecial states of the fungus were formed onChelidonium majus var.asiaticum andCorydalis incisa. The fungus was identified asMelampsora yezoensis based on the morphological observation of all the spore states. Urediniospores were able to infectS. erocarpa andS. pierotii as well asS. serissaefolia andS. jessoensis. Salix serissaefolia, S. eriocarpa, andS. pierotii are new uredinial and telial hosts ofM. yezoensis, andC. majus var.asiaticum andC. incisa are new spermogonial and aecial hosts of the fungus.
