State of the World's Fungi is the Kew Royal Botanic Gardens 2018 follow up to their award-winning State of the World's Plants website from last year. As this resource notes, the report is "the first of its kind outlining the state of the world's fungi, [...] highlight[ing] just how important fungi are to all life on Earth." The report and interactive website are organized into ten chapters, each accompanied by beautiful photographs and intriguing graphics. These range from New Discoveries (featuring 13 examples of the more than 2,000 new fungi species that were first described in 2017) to Useful Fungi (where readers can explore an assortment of ways that humans use fungi, such as in medicine, paper manufacturing, and leather processing) to Plant-Killers (featuring an interactive map showing the spread of ash dieback due to a fungal pathogen). Interested readers may download individual chapters or the full 92-page report as PDFs for additional text, graphics, and stunning photography.
