We have all heard of toadstools – and know that they are poisonous, but what many people don’t know is that a toadstool is actually a mushroom, not a separate type of plant. Toadstool is slang for “poisonous mushroom”. While there are some useful signs that a mushroom is poisonous, they are not consistent and all mushrooms of unknown origin should be considered dangerous to eat. Some of the things you can look for to try to determine whether a mushroom is poisonous are: it should have a flat cap with no bumps, it should have pink or black gills (poisonous mushrooms often have white gills), and the gills should stay attached to the cap (not the stalk) if you pull it off. But remember, while this is generally true of many types of mushroom, it is not always true.
