Agaricus bisporus is the interesting name for this mushroom. Agaricus, cleverly, means gilled mushroom. In the early days of mycology, every gilled mushroom was placed in the genus Agaricus. Now Agaricus is restricted to saprophytic mushrooms with a chocolate brown spore print and usually an annulus (ring) around the stalk. The epithet "bisporus" refers to the two-spored basidia lining the gills. You'll recall that most mushrooms have 4 basidiospores on each basidium, with each spore containing one of the 4 haploid products of meiosis.garicus bisporus produces only two basidiospores on each basidium. Each of the two spores contains two of the products of meiosis-- the consequence of this is that each spore already contains the nuclei needed for sexual reproduction and does not need to find a mate.

The methods for
growing straw rotting fungus agaricus bisporus are vastly different from growing most other sorts of mushrooms. Agaricus is a secondary decomposer, which means that bacteria and other fungi have to break down raw materials before Agaricus can grow. This is the process known as composting. Other kinds of cultivated mushrooms such as oyster mushrooms, enoki and shiitake are primary decomposers of wood, and composting is not necessary.
