Mushrooms
Mushrooms are the reproductive structures or “fruit” of certain fungi. Unlike green plants, fungi cannot use sunlight to make food, but the web-like root structures called mycelium decompose organic matter, which the organism utilizes for food. Mushrooms and truffles are important wildlife food. They are consumed by deer, elk, bear, small mammals, and mollusks. Some rodents rely on mushrooms for a significant part of their food supply and are, in turn, primary prey for larger species such as the northern spotted owl. Preserving the diversity of fungal species in forest ecosystems is essential to the wellbeing of our National Forests.
