Few people are indecisive 关于 edible mushrooms. They either love them or hate them. Yet these fleshy fruiting bodies of various species of fungi have a lot to offer to both your meal and your body.
What makes a mushroom edible? Edibility is defined as the absence of poisons and the presence of a desirable taste and smell. So it's not enough that a certain mushroom won't make you sick, it has to taste good as well! (Although we all know that taste is, well, a matter of taste.) Very few species meet these criteria, thus most mushrooms are considered inedible.
The practice of eating mushrooms dates back thousands of years. The first reliable evidence appears with the Chinese, and continues through time to today, spanning many different cultures.
From cultivated white buttons to elusive morels and truffles, edible mushrooms continue to be popular the world over. I've included much more information below, starting with important things to know. This covers both health benefits and dangers. We'll then move on to cultivated vs. wild mushrooms, and end with how to prepare. Guaranteed to make you hungry!
Edible mushrooms have uses beyond jazzing up your favorite recipe. They're known for their health benefits as well. Besides being low in sodium, fat, and calories, most mushrooms contain:
Of course, your mileage may vary depending on the type of mushroom and the environment in which it grew. To reap the greatest health benefits, it's best to consume mushrooms that were grown organically, or that were picked from a non-toxic environment. For more about the nutritional value of mushrooms, see this 页面.
Considering poor environments brings us to the downsides, the possible dangers. These dangers include man-made toxins, poisonous mushrooms, consumption with alcohol, and allergic reactions.
Avoid problems by educating yourself about what you're eating.
Edible mushrooms are either commercially cultivated or picked from the wild. You can also try cultivating them at home on a small scale. (It's a fun project!)
Commercially cultivated mushrooms are produced on farms and growing sites all over the world. Below is a list of some common species that go from growing room to grocery store. Click on the links for more information:
Wild mushrooms are a little trickier. Certain species have a mycorrhizal relationship with specific tree and plants. The fungus invades the roots of the tree, giving it access to energy-giving sugars and giving the tree greater surface area to absorb water and nutrients.
This relationship is not easily simulated in a lab, making mycorrhizal fungi difficult to impossible to cultivate. For this reason they must be picked from the wild, and are much more expensive than commercially cultivated species.
There's a huge industry around wild mushroom harvesting, one that's sparked much debate. It's not yet known what ecological impact removing so many mushrooms has on the environment. There's also controversy over how migrant mushroom harvesters are treated.
So the next time you're fortunate enough to be able to afford to purchase edible wild mushrooms, take the time to ponder where they came from, and who picked them for you!
Depending on where you live, you may be able to save yourself some money and any ethical crises by picking them yourself. This is not a task to be taken lightly, as a mistake can make you sick or worse. For more information see my introductory 页面 on mushroom identification, and the page on common poisonous mushrooms.

These lists are not the final word. There are more edible species out there to be enjoyed! (I'll continue to add more in the future).
Once you've acquired some edible mushrooms you're faced with the big question, to wash or not to wash?
You'll see all sorts of advice on whether or not to wash mushrooms before you eat them. The argument is that since mushrooms are mainly made up of water anyway, washing them may make them too wet and mushy. This disturbs the flavor and texture while cooking.
Others will advise that a quick rinse right before use isn't bad, and that a bowl of salt water is also a good way to remove bugs from wild mushrooms.
My advice? Most mushrooms do not need to be washed. I usually just wipe them off with a damp cloth. Take it on a case-by-case basis, and if your personal edicts of hygiene are telling you to wash them then do it.
Everyone has different tastes, but here are some other rough guidelines for edible mushrooms:
I've found a lot of people who say, "I don't like mushrooms" often mean, "I don't like the white mushrooms from the grocery store". There are so many other types of edible mushrooms with so many different flavors!
If you don't like one species, try another. Experiment and learn about all the delicious flavors that they bring to a meal. You'll be glad you did!
