| Abstract: | In May 2019, leaf spots were found on Amomum villosum in Guangxi Province, China. Light yellow-green spots first appeared at the tips or edges of leaves. A fungus was isolated from the leaves and identified as Colletotrichum fructicola based on morphological characteristics and molecular identification using the DNA sequences from ITS, TUB2, ACT, and GAPDH sequences. Similar leaf spots developed after leaves were inoculated with the isolate. This is the first report that C. fructicola causes leaf spots on A. villosum. |
