Funky Fungi: 5 Fun Mushroom Facts for Kids

Mushrooms may seem like strange little plants—but they’re not plants at all. They’re part of the fungi kingdom, and they do things plants could never do: digest food outside their bodies, glow in the dark, and even help trees talk to each other.

Whether you’re a nature lover, a homeschooler, or just curious about what’s growing in your yard, here are five fun mushroom facts to spark your imagination. 🍄

1. Mushrooms Are More Like You Than Like Plants

Mushrooms breathe in oxygen and exhale carbon dioxide—just like humans and animals¹. They also don’t make food from sunlight. Instead, they absorb nutrients from things like wood or leaves—just like you can see in our beginner’s guide to growing mushrooms at home. Some scientists say fungi are genetically closer to animals than to plants².

2. The Biggest Living Thing on Earth Is a Mushroom

There’s a single fungus growing in Oregon’s Malheur National Forest that spans more than three square miles underground. Known as the Armillaria ostoyae, it’s often called the “humongous fungus” and may be over 2,000 years old³.

3. Some Mushrooms Glow in the Dark

Called bioluminescent fungi, these mushrooms give off a natural green glow in the dark. Scientists believe the glow may help attract insects that spread mushroom spores⁴. You can find glowing mushrooms in forests around the world—including in parts of Texas.

4. Mushrooms Help Plants “Talk” to Each Other

Underground fungal threads called mycorrhizae connect the roots of trees and plants. Through this network, trees can share nutrients or send distress signals—almost like a forest internet⁵. Some researchers call it the “wood wide web.”

5. You Can Grow Mushrooms at Home (and Eat Them!)

Oyster mushrooms are one of the easiest types to grow indoors. With a basic kit, you can watch them fruit in just a few days. Some Texas farms even offer

for kids 8+ and families who want to try it hands-on⁶.

👀 Want to See Mushrooms Up Close?

Many local farms offer mushroom tours (see options in

or ) or growing classes where kids ages 8+ can:

1. See how mushrooms grow indoors (no sunlight required)
2. Learn about fungi’s role in the environment
3. Explore different mushroom shapes, textures, and colors
