This study was carried out to elucidate suitable spawn culture for an artificial cultivation of Neolentinus lepideus. The optimum culture conditions of the liquid spawn were deffated soy flour for main material, 12 days for culture period and 0.9 vvm for aeration volume, respectively. Sawdust spawn was appropriate for douglas fir sawdust and deffated corn flour (95 : 5, v/v) for mycelia growth and fruiting body formation. In case of liquid spawn, cultivation period was two shorter than sawdust spawn and mushroom yield was 111.9 g per 850 ml cultivation bottle. In conclusion, the suitable spawn for fruiting body production was found to be liquid spawn than sawdust spawn with considering cultivation period and mushroom productivity.
