Without fungi, mankind would likely suffocate under piles of dead and dying biological matter that would never decay. Medicines and other important contributions are made by these fungal organisms, not to mention the contribution they make to a pizza or steak sandwich! This classic Cooperative Extension publication gives young learners advice on identifying, collecting and displaying mushrooms. It touches on Mushroom Form and Function, Major Groups of Fungi, where and when to find Fungi and how to care for your collection.
