Shimeji (Japanese: シメジ, 占地 or 湿地) is a group of edible mushrooms native to East Asia, but also found in northern Europe.[1] Hon-shimeji (Lyophyllum shimeji) is a mycorrhizal fungus and difficult to cultivate. Other species are saprotrophs, and buna-shimeji (Hypsizygus tessulatus) is now widely cultivated. Shimeji is rich in umami-tasting compounds such as guanylic acid, glutamic acid, and aspartic acid.[2]
