Hericium erinaceus Identity & Plant Part
The botanical entity is Hericium erinaceus (Bull.) Pers., a tooth fungus that forms one white, cascading clump of soft spines in place of a cap with gills. In nature it grows on hardwood trunks, and cultivated crops are raised on wood-based substrates instead of grain.
The part used is the fruiting body, the spine-bearing mass. Vegetative mycelium and the substrate it grows through are not used. The distinction matters in this species because the two tissues are reported to carry different terpenoid families: hericenones, which are aromatic meroterpenoids, come mainly from the fruiting body, while erinacines, which are cyathane diterpenoids, come mainly from mycelium.
Common names for the species are lion’s mane, bearded tooth, tree hedgehog, monkey head and yamabushitake.
