Mushrooms: Keys to the Kingdom Fungi is an exhibit vividly portraying the intriguing lives and important roles of fungi in our environment. While the Fungi Kingdom includes more than one million species, this exhibit primarily focuses on the mushroom-producing fungi, but will touch on the idea of other fungi – including molds and yeasts – as well. The exhibit is based around 30 photographs of mushrooms (the fruiting bodies of fungi) in the wild, taken by Northern California plantspeople and naturalists, John Whittlesey and Jennifer Jewell.
