Abstract

The spermogonia and aecia of Melampsora epiphylla occur on larch (Larix leptolepis) and those of Pucciniastrum coryli on Abies firma, A. homolepis and A. veitchii. Salix chaenomeloides is first recorded as a telial host of M. chelidonii-pierotii, which passes its spermogonial and aecial state on Corydalis. These states of M. epiphylla and P. coryli, and the uredial state of Blastospora betulae, are described for the first time.
