Shiitake mushrooms (Lentinula edodes) are popular edible mushrooms found throughout China with high nutritional value including immune-boosting compounds. This study used computer modeling to map where these mushrooms currently grow and predict where they might be found as climate change continues. The research found that shiitake mushrooms will likely lose significant habitat area and shift northward and westward as temperatures rise and precipitation patterns change, suggesting urgent conservation measures are needed to protect wild populations.
