Agaricus bisporus, also known as public Button Mushroom, Mushroom or Mushroom Farm Table is one of the Basidiomycota fungi are edible and grows naturally in meadows and fields. Although this species is found only around Europe and North America, but populations of this species increased dramatically and is one of the most widely cultivated mushrooms in the commercial world.
Agaricus bisporus, which grew wild in nature has a gingery pileus and dark brown gills. However, a more convenient variation of the genus Agaricus white pileus, stem, and the contents of each white and brown gills.
A large number of retail outlets in Western countries is sold in the form of canned mushrooms and a fresh supply. Gill fungus is often removed during preparation. Button mushrooms that have been cooked can usually be found, especially for pizza and casseroles, eaten raw with a salad and so on. A mycology expert named Paul Stamets worried because the possibility of this fungus contain small quantities of hazardous chemicals agaritin kaseinogen commonly found in fungi but not identified how many levels of the chemical to cause poisoning to consumers and become a hot issue at this time.
Taxonomy and Nomenclature
Agaricus bisporus is known as the champignon de Paris in France. It is also called "champignon" (the French word for "fungus") in many countries.
Ordinary button mushrooms are grown is a member of the genus Agaricus where most members are edible, with flavors and quoted extensively throughout the world. The most known and popular is collected in the wild A. campestris, known as Meadow on North American mushroom or field mushroom in the UK and Australia. This species is found in the United States and Europe.
Agaricus bisporus Agaricus brunnescens derived from the name by Charles Horton Peck in 1900 prior to the change and disinonimkan A. bisporus. The name is derived from the alleged bisporus bi meaning two and sporus means of spores. Most of the Basidiomycota had four spores per basidia but this species has only two spores per bosidia.
Common species
These mushrooms are usually easy to be confused with a poisonous fungus, Amanita Virosa also known as the destroying angel people. Although looks similar in shape physically, but both species have a slight difference in shape at the site known as volva pileus and gill color. Amanita Virosa have gills that are white while most of Agaricus bisporus brown or pink. That's why we need to wash mushrooms, especially in the so volva fragments (debris) removed to determine the pattern, in addition to cutting specimens to identify the color of the young gills.
In addition, the "destroying angel" grow on wood, moss and live in symbiosis with fir trees.
Another somewhat similar fungus and Agaricus xanthodermus popular yellow. The fungus is usually found around the world in areas where grass can be identified by the smell of toxic chemicals, phenol and its contents will turn yellow when flaccid. This fungus affects the gastrointestinal, such as nausea and vomiting in some people.
Nutrition Nutrition
Button mushrooms are rich in vitamins and minerals. This particular mushroom contains vitamin B and potassium content is high. Raw mushrooms are free of cholesterol, fat and sodium. Mushrooms also have a very low total energy of five medium-sized button mushrooms together only 20 calories.
In addition, this fungus also has a unique flavor compared to other fungi. No special flavor is described; Mushroom described as a "timber" for having a somewhat bitter taste, but button mushrooms taste a little sweeter or a little "beefy".
Just as apples and potatoes, mushroom oxidizes quickly when exposed to air. When sliced and exposed to air for 10 minutes or more, these mushrooms become soft, change the color to a brownish-and lost its original flavor.
