Mushroom

What Is a Mushroom?

A mushroom is the pretty, fleshy part of a fungus that grows above the ground. You can find mushrooms on soil, leaves, or even on wood. They have a cap on top and a stem underneath. Under the cap, there are tiny lines called gills. These gills help the mushroom make tiny seeds called spores.

Mushrooms can appear very fast after rain. They come in many shapes, sizes, and colors. Some look like little hats, while others are round or even star-shaped! You might see mushrooms in forests, parks, or even growing on old tree trunks.

How Mushrooms Grow

Mushrooms start from something called mycelium, which looks like tiny threads underground. When the weather is just right, these threads make a mushroom pop up! Some mushrooms grow super fast—almost overnight. Others take many days to appear.

Even though the mushroom part doesn’t live long, the mycelium can stay alive for years. One group of mycelium in the United States is thought to be over 2,400 years old!

Mushrooms in Our Lives

People love mushrooms for many reasons. Some mushrooms are eaten and are tasty and good for you. The most common one you see in stores is called Agaricus bisporus. Other types, like shiitake and enoki, are also popular around the world.

Mushrooms help nature, too. They break down old leaves and wood, keeping the earth clean. Scientists are also studying mushrooms to see if they can help make medicines.
