Agaricus Bisporus

CAP
3-16 cm, dry, smooth or with compressed fiber or small spaces, white in some forms, and brown in other forms. Spherical or semi-spherical, bulged and flattened, straight. In some forms covered with bright colored grains or scales, in places kneading becomes red-brown. Immature mushroom hat is a thick, soft, serrated, white, and mercurial.

LEAFS
Separated from the stem, connected, reddish brown at first, eventually becoming dark brown to black. Leafs are found on the inner side of the cap and are arranged as wheel wires. Leafs are dense and free.

SPORE POWDER
Spore powder is dark brown.

STEM
2-8 cm long, 1-3 cm thick, solid, more or less flat, with scales below the ring. White, sometimes brown, sometimes with a ring disappearing in old age. The handle is stocky and hard to be separated from the cap-full at first, later becoming hollow, white, fungi in immature sometimes pink above the ring, on the mature champignon brown below the ring is soft. The ring is fairly thick, soft and white corrugated surface in regions of contact with the leaves during development.

MEAT
White, in the air becomes red on fungi in immature and brown in mature. The smell is mild, pleasant taste. The flesh is firm and hard.

GROWTH
Grow in moist, well-ventilated place. Temperature necessary to plant grown in perfect conditions is 50 to 70 º F. Relative humidity must be maintained above 70% or the fungus could be dried and cut in half.

PLANTING
Planting is done in the form of small pieces at a depth of 4-25 cm or simply to intersperse by hand.
___________________________________________________________________________________________
FERTILIZATION
Mushrooms can be best grown in a shallow box or tray filled with organic fertilizer. Horse manure has long been used but other materials can be used also: alfalfa hay, corn cobs, straw, saw dust, poultry manure. The vessels are filled with fertilizer which is allowed to boil at 140 degrees F, 4-6 days. The vessels are then shifted to a well ventilated place with temperature 70-80 degrees F.

CHEMICAL REACTIONS
In the reaction with KOH, no hat turns yellow or blushes.

PICKING
Picking can start at the first appearance of buttons and take up to 6 -7 weeks or longer. Each mature fungus is between 1 and 2 inches in diameter. Harvesting should be carried out once a day or every few days depending on germination.

MICROSCOPY
What is difference between champignons and other mushrooms, is microscopic: Unlike other species, its basidium holds two spores instead of four. They are chocolate-brown color.

HABITAT AND DISTRIBUTION
Scattered on the pizza, salads, finely chopped in stores, sometimes occurs in small groups on fertilized soil, in large groups, on lawns, etc.

EDIBILITY
Champignon is, of course, edible, but, like many other cultured foods, is not nearly as tasty as wild mushrooms. The edible part of the mushroom body is a nourishing or reproductive part of plants. Edible portion contains the handle of the hat.

RELATED SPECIES
Champignons in stores are usually white, but in recent years the mushroom industry has developed brown markings on the species, which are labeled as “Krimini” and “Portabelo” mushrooms (they are characterized by the fact that “portabelo” can mature skipping the initial phase). The closest relative of champignons, which was widespread and really wild, is the Agaricus Campeter
