Etymology

The name Agaricus bisporus is derived from the Greek word agarikon for a type of tree fungus, and bisporus which refers to the spore-bearing structure of the fungus. The common name "white button mushroom" refers to the appearance of the young, unopened fruiting bodies.

Description

Agaricus bisporus is a basidiomycete fungus, which means it produces spores on structures called basidia. The fruiting bodies, or mushrooms, are edible and are commonly found in grocery stores. They have a white to light brown cap and a stout stem with a ring. The gills are initially pink, then turn brown and finally black as the spores mature.

Cultivation

Cultivation of Agaricus bisporus is a major global industry, with the mushrooms being grown in more than 70 countries. They are grown on composted organic matter, often a mixture of horse manure and straw. The process involves several stages, including composting, spawning, casing, pinning, and harvesting.
