Fungi and Mushrooms

Mushrooms are neither plants nor animals. Although they look a lot like plants, they are actually more closely related to animals. When someone mentions mushrooms, perhaps the first you think of is finding edible mushrooms with your parents while on a walk in the forest. Mushrooms are a type of fungus, and fungi can be single-cell or multi-cell organisms. Some fungi are so small that you can only see them through a microscope. Such fungi are single-cell organisms. Baker’s yeast is an example of such a fungus. There are also larger fungi, such as the yellow boletus, the button mushroom, and the fly agaric. These larger fungi are multi-cell organisms.

Let’s take a closer look at the multi-cell fungi known as mushrooms: When you are in the forest, you will usually find mushrooms that have a stipe and cap. Most people think that the mushroom that they see above the ground is the actual mushroom. But what you see above the ground is just a tiny part of the whole. The parts you see above ground are called the “fruiting body.” The actual fungus is the mycelium. It grows underground, so we can’t see it. The mycelium consists of a mass of white filaments (tiny little threads) that can keep reproducing new fruiting bodies. Along with the fruiting body and the mycelium, the spores are another important part of multi-cell fungi. This is because most fungi and mushrooms use spores to reproduce. Spores are so tiny that you cannot see them with your naked eye. What you can see without a microscope is spore dust. When a mushroom reproduces, large numbers of new spores grow in the fruiting body. When they have grown, they fall out of the fruiting body. Then the wind picks them up and carries them off. Then new mushrooms begin to grow.

Humans have cultivated mushrooms and other fungi for centuries. Do you know why we grow fungi? For one, we cultivate mushrooms so we can eat them. Of course, we are careful to only cultivate so-called edible mushrooms and not poisonous mushrooms like the fly agaric. Two of the most common edible mushrooms are the button mushroom and the oyster mushroom. Maybe you’ve had a mushroom soup, a mushroom sauce, or salad with oyster mushrooms.

A second important reason why humans cultivate fungi is that they are important for making medicine. Various fungi have been important for making medicine in China for centuries. People already used fungi in medicine in the 1300s. They used fungi to make them feel better when they had colds, to improve their blood circulation, and to increase their strength. Fungi are still important for making medicine today. The most common modern-day application of fungi in medicine is in making antibiotics. When people have a serious or life-threatening illness, doctors often prescribe antibiotics. As you can see, mushrooms and other fungi are very important for humans.

Mushrooms are also important for our environment. They are known as decomposers. Much as bacteria do, decomposers break down decaying or dead things such as old plants, excrement, or animal carcasses. The decomposers convert these things into substances that are important for the environment. Without the help of decomposers, our world would gradually be overfilled with dead things and waste products.
