Wild Lentinula edodes (shiitake) strains are an important breeding material for developingnew varieties suitable for various consumer preferences and environmental conditions. Themorphological characteristics of 100 wild shiitake strains collected from 14 regions wereinvestigated in a sawdust block cultivation. The characteristics of their fruiting bodies werediverse. Among them, 38% of the caps was convex, 33% was broadly umbonate, 27%was applanate, and 2% was shallowly depressed. In terms of their stipes, 55, 23, and 22%were the column, clavate, and funnel type, respectively. The shape of the cap was themost diverse on Mt. Hwaak, whereas the shape of the stipe showed various phenotypesfrom various regions. Even among strains collected from the same forest, different types ofmushrooms were observed. In conclusion, wild shiitake strains that have adapted to variousenvironmental stress can be used to develop new varieties. Thus, securing various geneticresources and studying their traits are important for researching breeding technology.
