| Abstract: | Brown leaf spot of Lantana camara L. and L. montevidensis Briq. caused by Pseudocercospora guianensis (Stevens et Solheim) Deighton was found in Shizuoka, Chiba, Kagoshima and Okinawa Prefectures. Pathogenicity of isolates from the leaf spots was examined, and a taxonomic study as well as identification of the causal fungus was carried out. Similar leaf spots appeared on 7 to 25 days after inoculation with the isolates on Lantana spp., and the same fungus was re-isolated from the inoculated leaves. Two hitherto known Pseudocercospora species on Lantana, P. guianensis and P. formosana, were considered to be variations within one species, and we identified the causal fungus as P. guianensis due to priority.
