The fungus was obtained from the fresh leaves of Euphorbia sieboldiana, which were collected from the campus of China Pharmaceutical University, Nanjing, Jiangsu, People's Republic of China, in April 2013. After cultivation on potato dextrose agar (PDA) at 28 °C for 7 days, two pieces of the agar (about 1.0 cm³) were added to an Erlenmeyer flask (500 mL) with 150 mL of potato dextrose liquid medium, and the flask was incubated on a rotary shaker at 28 °C and 150 rpm for 5 days to prepare seed culture. Solid fermentation was carried out in 12 Erlenmeyer flasks (500 mL) each containing 120 g of sterilized rice and 10 mL of seed culture, and the flaks were cultivated at 28 °C for 30 days.
