Phellinus mori was a recently described species of Phellinus. In order to investigate the influence of different carbon sources, nitrogen sources, initial pH and temperature on mycelial growth of P. mori, its solid culture conditions were studied. The results showed that starch gave the maximum growth rate with less biomass, and glucose and maltose did the opposite. Yeast extract powder was the optimum nitrogen source. The variation of pH value between 5.5-8.0 did not affect the mycelial growth significantly, and the optimum temperature for mycelial growth was from 28 ℃ to 33 ℃ .
