Question: We have a lot of mushrooms showing up now that the fall rains have arrived. Are they safe to eat?
Answer: Some edible mushrooms are very similar in appearance to poisonous kinds and may grow in the same habitat. Edible mushrooms are known to be safe to eat because they have been eaten frequently with no ill effects. Poisonous mushrooms are known because someone ate them and became ill or died. There is no test or characteristic to distinguish edible from poisonous mushrooms.
Before eating any mushroom you will need to identify with certainty those species proven to be edible. At the same time, you should also learn to identify some of the common poisonous mushrooms, especially those that are similar to edible kinds.

If you decide to go mushroom hunting, WSU horticulturalists recommend the following: First, be sure of your identification - eat only kinds known to be edible. Do not eat mushrooms raw. Eat only mushrooms in good condition. Eat only a small amount the first time; even morels, generally considered to be excellent, may cause illness in some persons. Don't experiment. There is an old saying: "There are old mushroom hunters, and bold mushroom hunters, but there are no old, bold mushroom hunters!"
