A mushroom is a what?

A mushroom is a fungus. Fungi are a kingdom of organisms that includes yeasts, molds, and fleshy fungi. Mushrooms are the fleshy fungi that we typically see growing in the wild or in our gardens. They are made up of a network of hyphae, which are thread-like filaments. The hyphae produce spores, which are reproductive cells. When the spores are released, they can be carried by the wind or by animals to new locations, where they can germinate and grow into new mushrooms.
