This site from Utah State University Intermountain Herbarium is for learners of all ages. Dr. Robert Fogel (Professor of Biology/Curator of Fungi) and Patricia Rogers (Fungus Collection Coordinator and Editor of Fun Facts) have developed this resource to explain fungi and Mycology, the scientific study of fungi. Each Fun Fact is written in a clear, approachable manner and examines such topics as Caterpillar Fungus use in traditional Chinese Medicine, truffles, Penicillin, and slimes molds (not really molds), as well as associated scientific concepts like uses of data mining and information warehouses in Mycology. The following is one of this reviewer's favorites from this site. "The giant puffball (Calvatia gigantea) can be almost two feet long and contain 7,000,000,000,000 (7 trillion) spores. For comparison, there are about 31.6 million seconds in a year. If you held your breath for 7 trillion seconds, you'd be breathless for 221,817 years!" Huh? The site also has a small games section, the Mushroom Club, and offers more modest versions of the site in Spanish and Polish.
