The British Columbia mushroom industry is comprised of about 45 commercial Agaricus (brown and white button and Portobello) mushroom growers. Mushroom farms in BC are generally smaller than in other areas of North America, allowing growers to produce very high quality mushrooms through intensive crop management, enabling the spirit of family run farms. Some growers are now expanding the size of their operations to benefit from more efficient economies of scale.
The main crops are Agaricus bisporus (white button), along with a brown coloured strain of A. bisporus grown to three different sizes known as crimini (brown button, or Italian brown), portabellini (small portabella) and portabella. BC growers have developed a reputation for producing high quality mushrooms in North America through their dedication to a high level of management during the production process.
