A new species of Pseudocercospora and new record of Bartheletia paradoxa on leaves of Ginkgo biloba

A new species of Pseudocercospora is described on lesions restricted to the leaf margins of living leaves of Ginkgo biloba in Taiwan. The lesions were also colonized by the hyphomycete Scolecobasidium humicola. Telia of the basidiomycete Bartheletia paradoxa are first recorded from Japan. These three species are presumed to be saprobionts in the primary stage of litter decomposition or as weak pathogens. A short survey of fungi recorded from ginkgo with focus on ginkgo leaves is provided.
