Professor Richard Fortey has been a devoted field mycologist all his life. He has rejoiced in the exuberant variety and profusion of mushrooms since reading as a boy of nuns driven mad by ergot (a fungus). Drawing on decades of experience doing science in the woods and fields, Fortey starts with the perfect ‘fungus day’ – eating ceps in Piedmont. He introduces brown rotters and the white, earthstars and death caps; fungal annuals and perennials, dung lovers and parasites, even fungi that move through the trees like mycelial monkeys. We learn that the giant puffball produces more spores than there are known stars in the universe and fetid stinkhorns begin looking like arrivals from the planet Tharg. Amongst these and many other ‘close encounters’ of a fungal kind, the book attempts to answer the questions: what are fungi? Why did their means of reproduction escape discovery for so long? What role do they play in the development of life?
