Mushrooms Quiz – The Fascinating World of Fungi

Mushrooms are the fruiting bodies of fungi, a kingdom separate from plants and genetically closer to animals. Beneath the soil, fungi spread through networks of mycelium, and one honey fungus in Oregon covers nearly 10 square kilometers.

Many mushrooms are prized foods. Button, cremini and portobello are the same species at different stages, shiitake has been cultivated in East Asia for centuries and Italy prizes porcini and white truffles from Alba, found with trained dogs.

Foraging requires expert knowledge because some mushrooms, like the death cap, are deadly. Fungi also recycle nutrients in forests, and mushrooms can produce vitamin D when exposed to ultraviolet light.
