Edible Mushroom:Agaricus campestris

Edible Mushrooms....

Agaricus campestris


It is widely collected and edible mushroom, even by those who would not normally experiment with mushrooming. This mushroom is not commercially cultivated on account of its fast maturing and short shelf-life.Culinary uses of the meadow mushroom include sauteed or fried, in sauces, or even sliced raw and used in salads. In flavor and texture, this mushroom is almost completely identical to the white button mushrooms available in grocery stores in the United
States. Be sure to rinse well to dislodge any sand, and also watch out for small, white larvae which tunnel through the stems and caps.

Among the Similar Species mentioned below, there have been cases where the deadly toxic Destroying Angel mushroom (Amanita bisporiga) has been consumed by individuals who mistook them for this species.

Agaricus Bisporus

Agaricus bisporus,as edible mushrooms also known as table mushroom, portobello mushroom, cultivated mushroom or button mushroom, is an edible basidiomycete fungus which naturally occurs in grasslands, fields and meadows across Europe and North America, though has spread much more widely and is one of the most widely cultivated mushrooms in the world. The original wild form bore a brownish cap and dark brown gills but more familiar is the current variant with a white form with white cap, stalk and flesh and brown gills.

Some grocery stores in the Western world sell this mushroom in canned and fresh preparations. An agaric, its gills are often left on in preparations. It can be found cooked on pizzas and casseroles, stuffed mushrooms, raw on salads, and in various forms in a variety of dishes. Some mycologists, including Paul Stamets, have raised concerns that this mushroom contains trace quantities of a chemical agaritine known to have carcinogenic properties, though whether
levels are sufficient to cause harm in consumers is debated.

History of Edible Mushrooms

History of Edible Mushrooms

Mycophagy the act of consuming mushrooms, dates to ancient times. Edible mushroom species have been found in association with 13,000 year old ruins in Chile, but the first reliable evidence of edible mushroom consumption dates to several hundred years BC in China. The Chinese value mushrooms for medicinal properties as well as for food.
Ancient Romans and Greeks ate mushrooms, particularly the wealthier classes. The Roman Caesars would have a food taster taste the mushrooms before the Caesar to make sure they were safe. Mushrooms are also easily preserved, and historically have provided additional
nutrition over winter.

Many prehistoric and a few modern cultures around the world used psychedelic mushrooms for ritualistic purposes . Mushroom cultivation reached the United States in the late 1800s with imported spores from Mexico.

Poisonous Mushrooms in Northeastern North America

It is important to know that there are at least 10 reasons why people get sick from eating EDIBLE mushrooms:

1. Too many mushrooms are eaten – mushrooms are hard to digest; chewing well is advised.
2. Mushrooms are eaten raw or undercooked.
3. Too much butter is used in cooking the mushrooms.
4. Alcohol sometimes causes an adverse reaction when eating mushrooms.
5. The mushrooms are not in good condition; they are in some state of decomposition.
6. Some poisonous mushrooms are inadvertently mixed in with the edibles.
7. A personal allergy can cause anything from GI distress to a rash.
8. A prescription drug (MAO inhibitor) can cause a reaction with particular mushrooms, such as polypores.
9. Edible mushrooms that are badly canned can cause botulism.
10. A GI reaction (cramps, diarrhea) or nausea may occur after a meal, not related to the mushrooms eaten. A pre-existing virus may cause this.

There is also the Fear Factor. Someone may be eating wild mushrooms at your table for the first time ever, and be petrified, and become, or imagine becoming, ill because of stress.

Mushrooms known to cause death in Northeastern North America:
1. Amanita virosa AG 551
2. Amanita phalloides AG 543
3. Galerina autumnalis AG 620
4. Lepiota josserandii AG 517
5. Gyromitra esculenta AG 336

Because of the very real possibility of misidentification (for whatever reason) and the very real consequences of severe mushroom poisoning, the following is advised:

Do not eat any Amanitas even though some are known to be edible.
Do not eat any LBM (Little Brown Mushroom).
Do not eat any small species of Lepiota.
Do not eat any large Lepiota without first finding out its spore color. Definitely avoid the green-spored Lepiota, Chlorophyllum molybdites -- it will make you seriously ill.
Do not eat any Gyromitra (False Morel), at least not when found east of the Mississippi River.
Do not eat Jack O'Lantern, Omphalotus olearius, mistakenly thinking it is a chanterelle. --
Always keep a fresh specimen in the refrigerator, in case identification is needed for treatment.

Mushrooms for Good Health?

Mushrooms for Good Health?
In general, I advise against eating a lot of the cultivated white or "button" mushrooms found on supermarket shelves throughout the United States (portobello and crimini mushrooms are the same species). They are among a number of foods (including celery, peanuts, peanut products,
and salted, pickled, or smoked foods) that contain natural carcinogens. If you do eat these varieties, never eat them raw and cook them thoroughly over high heat; that will break down some of the toxins.

Instead of button mushrooms, I recommend seeking out the more exotic varieties, which are becoming increasingly available in the United States. Some are edible mushrooms and can make a delicious addition to your diet, but some are strictly medicinal mushrooms available in dried, liquid extract or in capsule form.

Here's a brief guide to my favorites:

* Shiitake: These meaty and flavorful mushrooms contain a substance called eritadenine, which encourages body tissues to absorb cholesterol and lower the amount circulating in the blood. Dried shiitakes, available at Asian grocery stores, are also effective. Fresh ones are readily available thanks to domestic cultivation. (To prepare, remove stems or slice fresh ones thinly; they are often tough.)
* Cordyceps: A Chinese mushroom used as a tonic and restorative. You can buy whole, dried cordyceps in health food stores and add them to soups and stews, or drink tea made from powdered cordyceps. get cordyceps in liquid or capsule form. * Enoki: Slender white edible mushrooms that need only brief cooking and have a very mild taste. Enoki mushrooms have significant anticancer and immune-enhancing effects.
* Maitake: This delicious Japanese edible mushroom is also called "hen of the woods" because it grows in big clusters that resemble the fluffed tail feathers of a nesting hen. Maitake has anticancer, antiviral, and immune-system enhancing effects and may also help control both high blood pressure and blood sugar levels.
* Reishi: Strictly a medicinal mushroom, not a culinary one, reishi is woody, hard, and bitter. Like maitake and other related mushrooms species, reishi can improve immune function and inhibit the growth of some malignant tumors. It also shows significant anti-inflammatory effects, reduces allergic responsiveness, and protects the liver. You can buy dried, ground mushrooms and use them to make tea if you don't mind the bitterness. Otherwise, buy reishi tablets, liquid extracts or capsules, which are available in health food stores and follow the recommended dosage. Allergies to edible mushrooms are rare, but some people do find them hard to digest.
