The mushroom tattoo might not be one of the most popular but they do interest many. A mushroom (or toadstool) is the fleshy, spore-bearing fruiting body of a fungus, typically produced above ground on soil or on its food source. Mushroom tattoos can be very colorful. They can be executed in a cartoon style, in a realistic way, or even in a psychedelic or trippy way. There are many symbolic meaning for the mushroom tattoo but it is ultimately up to the wearer to give it its true meaning.
