This study presents the cultivation of Pleurotus ostreatus using charcoal made from used paper. On crushed charcoal rice bran medium in a bottle, the yield of fruit bodies was greater than that on the Sugi sawdust rice bran medium. Moisture content of the medium had a greater influence on the yield of fruit bodies, the mycelial growth and days after fruiting induction than the carbonization temperatures or the charcoal size. These results suggest that charcoal made from used paper can be used for the cultivation substrate of P. ostreatus. In the cultivation using a solid charcoal, mycelia were accumulated into the medium. It was shown that cultivation with solid charcoal was possible, though the yield of fruit bodies was less than that in the sawdust medium.
