The objectives of this study were to evaluate applicability of food waste compost (FWC) as a substrate for cultivation of Ganoderma lucidum, Lentinula edodes, and Pholiota adipose, and to determine contents of Ca, Mg, Na, and K in fruiting bodies (FB). FB yield per substrate in FWC-free controls was $53{pm}4g/kg$ for G. lucidum, $270{pm}90g/kg$ for L. edodes, and $1,430{pm}355g/kg$ for P. adipose. Substrates supplemented with FWC showed the highest FB production at FWC content of 10% for G. lucidum ($64{pm}6g/kg$), and 13% for L. edodes ($665{pm}110g/kg$) and P. adipose ($2,345{pm}395g/kg$), which were 1.2~2.5 times higher than the values for the controls. P. adipose contained higher amounts of mineral elements than the other species. Ca, Mg, Na, and K content in FB did not show a significant relation to FWC content.
