The purpose of this study was to understand the effects of mushroom occurrence by forest thinning in the Pinus koraiensis stand. The leaf area index, air temperature and relative humidity, soil water content, and amount of throughfall were measured in the P. koraiensis stand. The more throughfall of 72 mm / year and about 1 °C higher soil temperature were observed in the P. koraiensis stand than non-treatment stand. Relative humidity and soil water content were positively correlated with the occurrence of mushrooms in the P. koraiensis stand. The correlation coefficient of throughfall and ectomycorrhizal mushrooms was 0.93 in the thinned stand of P. koraiensis. 6 less species of ectomycorrhizal mushrooms and 7 more species of saprophytic mushrooms were observed in the thinned stand than in the non-treatment stand of P. koraiensis. Suillus pictus, an ectomycorrhizal mushroom, was found in a distribution of 100 pieces in the non-treatment stand and 69 pieces in the thinned stand of P. koraiensis. But the species diversity index of ectomycorrhizal mushrooms was 0.823 in the non-treatment stand and 0.911 in the thinned stand of P. koraiensis. In conclusion, forest thinning increased throughfall by decreased crown density. Accordingly it increased the number of ectomycorrhizal mushrooms. An increase of felled trees in the forest thinned sites caused an increase of saprophytic mushrooms.
