Next time you pass by a mushroom, consider this: underneath that cap and stalk lies a network of thread-like filaments that could spread out up to a radius of one kilometer! Welcome to the "Marvelous Mystery Tour!" There are between 5,000 and 10,000 species of mushroom just in Japan. Yet only about 3,000 have names. And they come in all shapes, sizes, colors ... and odors! Mushrooms are without a doubt integral to forest ecology. Join us as we enter a whole new world just by lowering our gaze?
