What you’ll learn

Not a Plant, Not an AnimalLearn that fungi are their own kingdom, and that a mushroom is just the tip of a much bigger hidden body.Fungi are not plants or animals but a third kingdom. The mushroom you see is only the tip, while the real body is a web of tiny threads called mycelium hidden underground. Fungi eat by growing into their food, and they come in many shapes, including molds and yeasts.
Spores and RecyclersDiscover how fungi spread using spores and why they are nature's most important recyclers.Fungi make new fungi with billions of tiny spores that drift on wind and water. They are nature's recyclers, growing into dead logs and leaves and breaking them down into rich soil, so nothing in the forest goes to waste.
The Biggest Living ThingMeet the giant Oregon honey fungus and learn how scientists discovered it is one enormous organism.The largest living thing on Earth is a giant honey fungus in Oregon, spread across several square miles as one connected organism. It is thought to be over 2,000 years old. Scientists proved it was a single fungus by testing matching samples from far-apart spots.
Fungi Friends and SafetyExplore how fungi help make food and medicine, and learn the vital safety rule about wild mushrooms.Yeast makes bread rise, fungi help make cheese, and mold gave us the life-saving medicine penicillin. But the golden rule is to never eat wild mushrooms, because some are deadly poisonous and look just like safe ones. Only eat mushrooms from a store.

Questions this course answers

What group, or kingdom, do mushrooms belong to?

Fungi are not plants and not animals. They belong to their very own third kingdom, the fungi.

The mushroom you see is only part of the fungus. Where is the rest?

The mushroom is just the tip. The real body is a huge web of tiny threads called mycelium, hidden underground or in a log.

How does a fungus eat, since it cannot use sunlight?

Fungi grow their threads right into their food, break it down with special juices, and soak the food back up like a sponge.

Which of these is also a fungus?

Molds and yeasts are fungi too. The fungi kingdom includes mushrooms, molds, and yeasts in many shapes.

How do fungi make new fungi, if not with seeds?

Fungi make billions of tiny spores that drift on the wind or water. When a spore lands in a good spot, it grows a new fungus.

Why is the forest not buried under dead leaves and logs?

Fungi are nature's recyclers. They break down dead wood and leaves into rich soil, keeping the forest healthy.
