In this captivating debut, Sheldrake-mycologist extraordinaire who features in the chapter in Robert Macfarlane's Underland about the World Wood Web-explores the spectacular world of fungi: astonishing organisms that, neither plant nor animal, are found throughout the earth, the air and in our bodies, though 90% of their species remain undocumented. They can solve problems without a brain, stretching traditional definitions of what we think of as "intelligence", survive nuclear radiation and live on unprotected in space, and can manipulate animal behaviour in extraordinary, unsettling ways we struggle to explain. But before it all gets too creepy, we're reminded that fungi give us bread, alcohol and life-saving medicines; and that their ability to digest plastic, explosives, pesticides, crude oil and other messes of human creation make them vital to restoring the health of the planet, too. For those of a hallucinogenic bent, there is also chapter on magic mushrooms and psilocybin which convinced me that Silicon Valley-style micro-dosing might be quite a good idea. Read this astounding, mind-altering book, and I promise you you'll never look even at the mildew in the bathroom, the mould on your marmalade, or mushrooms in the supermarket in the same way again.
