We conducted this research to develop the medium for some edible mushroom cultivation using shiitake waste log which is abandoned after cultivation of shiitake mushroom because those bed logs can not be recycled. The isolates of P. ostreatus(POS-012), P. eryngii(PER-005), G. frondosa(GFR-001) and F. velutipes(FVE-001) were selected and examined for mycelial growth on sawdust media prepared from shiitake waste log. Mycelial growth of selected isolate were satisfactory on the sawdust extract media using acasia(Robinia pseudo-acacia), neutinamu(Zelkova serrata) and kangchamnamu(sangsuri, Quercus acutissima) which are no shiitake-inoculated. Although the mycelial growth of the isolate were poor on the sawdust media prepared from Quercus spp., sawdust of neutinamu, (Zelkova serrata), beotnamu, (Prunus serrulata), orinamu(Alnus japonica), eunsuweonsasinamu(Populus tomentiglandulosa) and chestnut(Castanea crenata) were excellent for mycelial growth. However, shiitake logs which are infected with harmful fungi such as Hypocrea spp. were useful as recycle materials for mushroom cultivation.
