About this ingredient
Cluster mushroom group sold under the shimeji name in Japan — primarily bunashimeji (Hypsizygus marmoreus, cultivated) and the much rarer hon-shimeji (Lyophyllum shimeji, partially cultivated since 2004). Nagano dominates cultivation; bunashimeji is the supermarket staple of the cluster category. Used in soups, stir-fries, hot pots, and increasingly in plant-based-protein retail. Distinct from existing maitake / shiitake / enoki / eringi entries.
