Mushroom is cultivated as one of the major economical crops in many areas in Korea. The total production has steadily increased from approximately 186,400 M/T in 2007 to 190,104 M/T in 2009. The oyster mushroom, Pleurotus ostreatus, showed the 2th production to 46,598 M/T in 2011. This study was carried out to investigated optimum mixing ratio of Korean natural Acer tegmentosum for production of functional oyster mushroom. Mycelial growth of Pleurotus ostreatus showed the highest growth at the media of 10% Acer tegmentosum and was decreased to increase of Acer tegmentosum addition ratio. But mushroom mycelial growth at Acer tegmentosum media was slower than that of the control. Total nitrogen and carbon source of Acer tegmentosum was 0.19% and 44.4%, respectively and C/N ratio was 234. Total nitrogen source and pH of substrates mixed with Acer tegmentosum were 2.7∼3.0 and 4.8∼5.0, respectively. The contents of P2O5 and K2O were decreased by increasing Acer tegmentosum but the contents of CaO, MgO and Na2O were no significant difference. The contents of Fe and Mn were decreased according to increasing of Acer tegmentosum, but the contents of Zn and Mn were no significant difference. Yields of fruiting body and diameter and thick of pileus were the highest at 10% Acer tegmentosum. The L value of pileus was the highest at the 30% Acer tegmentosum during mushroom harvest, but there was no significant difference in the a-value and the b-value. The contents of P2O5,, CaO, MgO and Na2O of fruiting body were no significant difference, but contents of Cu was decreased and Fe was increased according to increasing of Acer tegmentosum.
