What Is a Mushroom?

A mushroom is the fruit of a hidden underground network that eats by dissolving things around it.

  1. Step 1 of 5

    A fungus is not a plant.

    A plant Builds sugar fromsunlightA fungus Dissolves food, thenabsorbs it

    It has no leaves and makes no sugar from sunlight. It feeds by releasing chemicals that break food down outside itself, then absorbing it.

  2. Step 2 of 5

    The real body is a network of threads.

    What you notice Threads spreadingthrough the soil

    Fine threads spread through soil or wood, sometimes across hectares. The mushroom is only the part built to make and release spores.

  3. Step 3 of 5

    The cap is a spore launcher.

    Under it, gills or pores carry millions of spores. The cap keeps rain off them and holds them high enough for a breeze to catch.

    Fungi are how dead things disappear.

    They are the main recyclers of wood. Without them, forests would bury themselves in fallen trunks and the nutrients would never return.

  5. Step 5 of 5

    Many plants are quietly partnered with them.

    Fungal threads wrap tree roots and trade water and minerals for sugar. Most forest trees depend on a partner you never see.

    Some fungal networks are among the largest living things known, spreading for kilometres through forest soil.

The short version

A mushroom is the spore-launching fruit of a hidden thread network that digests its food outside itself and recycles the forest.

Try it yourself

Lay a cap gills-down on paper overnight under a bowl. The spores fall out and print the gill pattern.
