Lion’s Mane, Hericium erinaceus (bearded tooth mushroom, satyr’s beard, bearded hedgehog mushroom, pom pom mushroom, or bearded tooth fungus), is an edible mushroom belonging to the tooth fungus group. Native to North America, Europe and Asia it can be identified by its long spines (greater than 1 cm length), its appearance on hardwoods and its tendency to grow a single clump of dangling spines. In the wild, these mushrooms are common during late summer and fall on hardwoods, particularly American Beech. Hericium erinaceus contains a number of polysaccharides, such as B-glucan, heteroglucans, heteroxylans, as several cyanthane derivative triterpenes known as hericenone and erinacine. These latter compounds are found in the fruitbody and mycelium respectively. Hericium erinaceus has long a history of traditional use.
