Cultivated Agaricus

We all know the mushroom Agaricus bisporus very well: these are the mushrooms in your punnets, supermarkets, delis, restaurant and fields. Button mushrooms, closed-cup mushrooms and flat mushrooms are all the same white type of Agaricus bisporus, just at different growing stages (two days, four days and six days, respectively). And it’s the same for chestnut mushrooms and portobello mushrooms, which are different sizes of the brown strain. For wild Agaricus.
