Hunting for mushrooms can be a fun hobby as well as a rewarding experience – hundreds of edible mushrooms are tasty and safe to eat – but beware! Finding wild mushrooms is not difficult, but it can be challenging to determine which mushrooms are safe to eat. Poisonous mushrooms can often look similar to edible mushrooms, which makes finding new mushrooms to eat a risky procedure. Most poisonous mushrooms will not kill you, but if you eat a bad one, you could end up with nausea, vomiting, cramps, or aches – or end up in the hospital!

Be Safe Not Sorry!

To avoid unnecessary risks, only eat mushrooms that you are 100 percent sure are safe to eat. Take care to study the variety of mushrooms that grow locally in your area, as the exact appearance of each poisonous mushroom can vary by region. Unless you are absolutely sure, with no question at all, that the mushroom is safe to eat – leave it alone! You do not want to poison yourself or your family with harmful mushrooms. Want to be absolutely sure? Buy a guidebook, and contact a local agricultural office to help identify all the mushrooms you’ve collected, so that you can learn to identify ‘good’ mushrooms before you start foraging for edible mushrooms on your own.

How To Check Mushrooms

The identifiable characteristics of a mushroom (these are the parts you’ll be comparing to your mushroom guide or explaining to the ag office over the phone) include the appearance of the cap, the size, stem, texture, and growing region of the mushroom, as well as the ‘spore impression’ – you’ll need to ‘impress’ the cap against white paper to see what color comes off to figure this out. According to AmericanMushrooms, you can use the following steps to take a spore impression of each mushroom you find:

Cut off the stem of the mushroom.
Place the mushroom cap side up onto a piece of clear, sturdy plastic.
Place a clear jar or container over the mushroom and plastic.
Allow the mushroom to sit overnight.
Remove the mushroom from the plastic carefully to reveal the spore print.

Steer clear of any mushrooms that look the slightest bit like the deadly or poisonous kinds outlined below (click each image to view details about identification):

Deadly webcap: Rounded mushroom cap with a point in the center. Brown or tan in color. Wide cap with a long, thin stem. Wide gills often connected to the stem. Lives in pine woods or acidic soil. Most often seen between summer and fall. Photo by Eric Steinert

Death cap: Deadly! Grows near and under wood, primarily oak. Shaped like the top of a rocket with a narrow cap and long stem. Often has a greenish tint to its white flesh. Has a metallic sheen. Image by Stanisław Skowron

Destroying angel: Deadly! Short, round cap. Looks similar to white mushrooms you see at the grocery store. Short, stubby stem. Grows near live oak trees. Sprouts from late winter through spring. Image by Ben DeRoy

Fly Agaric: Typical “toadstool” appearance with red flesh and white spots. Can also be brown or even white. May have a curved or flat cap. Thick, white stem. Loves wooded areas. Most often seen in the fall. Photo by Anne Burgess

Jack-o-Lantern: Orange color. Wide, flat cap. Nearly non-existent stem, although some varieties have them. Often grows against trees and roots. Likes live oak trees and eucalyptus trees. Spore print is yellow or cream-colored. Stipe can travel to the base of the stem. Photo by Jason Hollinger

Green-spored: Lepiota: This mushroom is often found growing in suburban lawns. Has a wide, flat cap with a large stem. Whitish in color, with brown or greenish spots. At maturity, the gills are green. Often grows in a fairy ring shape. Photo by Strobilomyces

Little Brown Mushrooms: This is not just one variety of mushroom, but rather a whole variety. Most small, brown mushrooms of any kind are poisonous. Stay away from any small, brown mushrooms that you find. Image by Eric Steinert
