Members of the fungal kingdom-the decomposers, the fermenters, the pathogens, the symbiotes-play critical roles in the ecology of our planet and have provided both benefits and hazards to humans for millennia. Pathogenic fungi are responsible for ca. 1.5 million deaths each year, yet other members of the Kingdom Fungi provide foods, medicines, industrial products, and more: a window for researchers into the workings of all eukaryotes. In The Fungal Kingdom, an international team of experts has assembled reviews by more than 170 mycologists, cell biologists, systems biologists, mathematicians, geneticists, and genomicists that cover the latest research and knowledge about all aspects of the Eumycota. The Fungal Kingdom is a rich collection of articles on all things fungi. These reviews present the latest fungal research and the impacts of fungi on agriculture, ecology, human health, and industrial applications as well as what lies ahead.
