👉 Pygigidia is a type of edible fungus that grows on the skin of certain types of mushrooms. It's often referred to as a "fungus in the skin" because it can grow on or under the skin of various fungi such as oyster mushrooms, chanterelles, and truffle mushrooms. This type of fungus is also known for its unique appearance, which includes a white cap with black spots that are visible when you rub against the skin.
