Fungi are everywhere but they are easy to miss. They are inside you and around you. They sustain you and all that you depend on. As you read these words, fungi are changing the way that life happens, as they have done for more than a billion years. They are eating rock, making soil, digesting pollutants, nourishing and killing plants, surviving in space, inducing visions, producing food, making medicines, manipulating animal behavior, and influencing the composition of the Earth's atmosphere. Fungi provide a key to understanding the planet on which we live, and the ways that we think, feel, and behave. Yet they live their lives largely hidden from view, and over ninety percent of their species remain undocumented. The more we learn about fungi, the less makes sense without them.
