Classification

Agaricus belongs to the class of basidiomycetes (Basidiomycetes), order Agaricales, or plate (Agaricales), Agaricales family, or Mushroom (Agaricaceae), old mushroom (Agaricus), which under natural conditions has more than 60 species .

Species of mushroom mostly cosmopolitan, they are distributed on all continents, and only a small number of species, mostly desertmushrooms, have a limited range of deserts and semi-deserts of Central Asia and North America .

Similarly, the higher flowering plants, in which the cycle of growth and development continues, "from seed to seed" in the mushroom this cycle runs from controversy to controversy .

Growth of mycelium depending on temperature, moisture content and density of the substrate is continued for 10 to 20 days .

When the beginnings of fruiting bodies reach the size of a pea, in the differentiation of these tissues to form a cap and stem of the fruiting body .

Clavate basidia are parallel processes of cells, where the developing spores . Agaricus bisporus has on eachbasidia two disputes, wild species - four (Fig. 4) . The growth of fruiting bodies is very slow at first, then reaches a maximum value and almost since the end of the full differentiation of organs and tissues fruiting bodies grow within 10 - 15 days . During this period the formation and development of the dispute, the fruiting bodies grow upsize commercial mushroom . Cap fruiting body is revealed for 1 - 2 days . During this period, disputes reach biological maturity, detached from the processes of basidia, crumble in the form of tiny dark brown dust and, once in favorable conditions, germinate and form young arachnoid mycelium (Fig. 5) .

Like This,tightly interconnected in parallel on the surface of the hyphae of the cap to protect against adverse external conditions (temperature variation, mechanical damage, etc. . d . ), and constitute a coating cloth (cuticle) .
