Summary:In 2020, a brown felt was observed on persimmon (Diospyros kaki) in persimmon orchards, Sangju, Korea. The symptom on persimmon was white to grey mycelial mats on some areas of the branches. Each mat progressively expanded until the mats coalesced to occupy larger areas and finally girdled the branches. The disease branches were covered with brown-colored mold, consisting of hyphal mats of the pathogen. Optimum temperature for mycelial growth was 30oC. On the basis of mycological characteristics, pathogenicity test, and molecular analysis with complete internal transcribed spacer rDNA region, the causal fungus was identified as Septobasidium sp. This is the first report of brown felt caused by Septobasidium sp. on persimmon in Korea.
