"Fungi constitute the most poorly understood and underappreciated kingdom of life on earth. Though indispensable to the health of the planet (as recyclers of organic matter and builders of soil), they are the victims not only of our disregard but of a deep-seated ill will, a mycophobia that Stamets deems a form of "biological racism." Leaving aside their reputation for poisoning us, this is surprising in that we are closer, genetically speaking, to the fungal kingdom than to that of the plants. Like us, they live off the energy that plants harvest from the sun. Stamets has made it his life's work to right this wrong, by speaking out on their behalf and by demonstrating the potential of mushrooms to solve a great many of the world's problems."
