We collected and identified 5,721 ectomycorrhizal fruiting bodies (EcM) from Naejangsan National Park from June 2004 to 2013, belonging to 1 phylum, 1 class, 6 orders, 19 families, 40 genera, and 196 species. Of these, 2,249 individuals were identified as 89 species belonging to 11 genera in 7 families in the Agaricales; 1,511 were identified as 43 species belonging to 2 genera in 1 family in the Russulales; 1,132 were identified as 50 species belonging to 21 genera in 6 families in the Boletales; 793 were identified as 8 species belonging to 3 genera in 2 families in the Cantharellales; 29 were identified as 3 species belonging to 2 genera in 2 families in the Thelephorales; and 7 were identified as 3 species belonging to 1 genus in 1 family in the Gomphales. Thus, most of the EcMs identified belonged to the following 3 orders: Agaricales, Russulales, and Boletales. Russulaceae were most common (43 species), followed by Boletaceae (39 species), and Amanitaceae (27 species); most individuals were Russulaceae (1,511), followed by Hydnagiaceae (1,071) and Boletaceae (804). The monthly distribution showed that the greatest number of individuals and species of EcM, including the dominant ones, occur around July~September at an elevation of 200~299 m, diminishing markedly above 600 m. The greatest number of individuals and species, including the dominant ones, were collected in the period with average temperatures $25.0{\sim}26.9^{\circ}C$, lows of $21.0{\sim}22.9^{\circ}C$, and highs of $30.0{\sim}31.9^{\circ}C$, relative humidity > 76%, and rainfall > 400 mm.
