Abstract
"Shimeji" mushrooms include at least three species: hon-shimeji (Lyophyllum shimeji), shaka-shimeji (L. fumosum), and Hatake-shimeji (L. decastes). Of these, hon-shimeji is the most prized as a delicacy. The Latin names of these three shimeji mushrooms were established in the mid-1970s. Recently, the biological species of L. shimej has been discussed based on results of mating tests, and its phylogenetic analysis has also been conducted. In this paper, We review the taxonomic treatment of L. shimeji in Japan over the previous several decades and discuss the needs for future taxonomic studies of shimeji mushrooms.
