The lawn mower mushroom is one of the most common and widely distributed lawn mushrooms in the Pacific Northwest and it often grows in large numbers. This mushroom is mildly poisonous and should not be eaten by children or adults and try to keep your pets from eating them as they can have a serious effect on cats livers and kidneys and can make dogs ill. Many dogs have not survived after eating these mushrooms. They will eat them by accident when they are eating grass.
As a parent, l always taught my children not to eat anything from the lawn or forest without showing me first. This led to some great chances to teach them about the plants, mushrooms and animals from the the BC coast.
