The Bearded Tooth Mushroom (Hericium erinaceus): The bearded tooth mushroom looks like a mop and apparently tastes like lobster. Known as the bearded tooth mushroom or the lion's mane, the Hericium erinaceus is an edible, medicinal mushroom that belongs to the tooth fungus group, which are mushrooms that feature teeth-like ridges on the underside of their caps. Spores are also produced in the teeth before being released for reproduction. Interestingly, these ridges always grow perpendicular to the Earth.
