Beware of These 5 Toxic Mushroom Lookalikes

Foraging for wild mushrooms is both an art and a science. There’s nothing like scouting out these prized morsels to fill your empty belly. 

But all it takes is one mistake for a scrumptious meal to become a deadly disaster. After all, the difference between a toxic mushroom and a gourmet delight can be nearly invisible.

Today, we’re covering five poisonous fungi that are easy to confuse with the real thing.

Let’s dig in!

About Mushroom Foraging

Many people are intrigued by the idea of foraging for wild mushrooms. Perhaps it takes us back to our hunter-gatherer ancestors, who learned to distinguish delectable treats from deadly specimens. Or maybe it’s the dopamine hit that comes with spotting a bright orange chanterelle peeking out from the ground cover. 

Whatever the reason, it’s a great way to connect with Mother Nature and cut costs on your grocery bill. 

But before you don your boots and head into the wilderness, you’ll need to know precisely what you’re looking for. Guidebooks are an essential tool for safe, successful mushroom hunting. Heck, grab two or three, so you have plenty of reference material. 

That said, we suggest tagging along with an experienced forager before setting out on any solo missions. Many folks who’ve been out in the field for a while have learned to recognize the subtle differences between gourmet mushrooms and toxic varieties. And these minute variations can be life-threatening. 

Remember, there’s no margin of error here. Assume any fungi is deadly until you know with certainty that it isn’t.

Toxic Mushrooms to Look Out For

Although we’re not qualified to teach you everything to know about foraging, we can help you distinguish between some of the most common lookalikes. Here are five toxic mushrooms to avoid when you’re combing the forest for fungi.

#1 Jack O’Lantern Mushrooms

Foodies and gourmet chefs revere golden chanterelles as the ultimate trophy. The fact that they grow exclusively in hardwood forests only adds to their appeal. Despite many attempts, farmers and scientists haven’t found a way to domesticate them. If you get lucky and spot these at your farmers market, that means someone foraged them. 

Denoted by their creamy yellow to bright orange flesh, these tender morsels might give off a mildly fruity smell. You’ll find them popping out of leaf litter and grassy undergrowth.

But toxic jack o’lantern mushrooms are easy to mistake for chanterelles. They’re a similar color but offer a few distinctions. First, the lookalikes are often much larger and grow in sizeable clusters. Next, chanterelles have gill-like ridges running from the bottom of the cap to the stem. Jack o’lanterns have true gills that fork sharply. At night, they might glow in the dark.

Finally, when you peel the skin of a chanterelle, the stem will be pale. In contrast, jack o’lanterns are bright orange throughout.

Expect nausea, vomiting, and intense stomach pains if you accidentally ingest these copycats.

#2 Destroying Angel Mushrooms

It’s easy to confuse this toxic variety with edible button mushrooms and puffballs, especially when they’re young. However, eating half the cap of a destroying angel can be deadly, even for a healthy adult. 

These fungi have bright white caps and stems. They belong to the Amanita genus, and one of their most distinctive features is a series of loose flecks on top, which are remnants of the veil they break out of as they fruit. 

Destroying angels form symbiotic relationships with certain trees and often grow near their roots. Depending on the region, you might see them in summer and early fall. 

#3 False Morel Mushrooms

Morel mushrooms are another prized find among foragers. Both yellow and black varieties emerge in the spring. With a creamy, hollow stem and pitted cap that ranges from tan to black, they’re peculiar organisms. You’d think nothing on Earth could resemble their odd aesthetic, but you’d be wrong.

Instead of the honeycomb appearance of true morels, their poisonous counterpart resembles a wrinkly, reddish-brown brain. Additionally, they’re not completely hollow. Instead, they contain cotton-like fibers. If you have any doubt, slice through it to see what is or isn’t inside.

Unlucky foragers who eat these might have nausea and vomiting, followed by seizures and other neurological problems. False morels are also carcinogenic, so it’s best to steer clear at all costs.

#4 Death Cap Mushrooms

Death caps, another Amanita species, are responsible for more toxic mushroom poisonings than any other on the planet. They’re easily mistaken for puffballs or tropical straw-paddy varieties, but their unique blend of noxious compounds makes them deadly. 

What’s even more confounding is their nondescript appearance. They can be off-white, yellow, brown, or green, with a sticky or slimy cap. These killer shrooms often grow about five inches tall and six inches across. You might notice a sickly sweet aroma when you cut them open. However, others describe it as a chemical smell. 

Death caps usually appear in the fall and prefer habitats with pine, oak, and dogwood trees.

Amanita phalloides, commonly known as the Death Cap, is a poisonous mushroom.

#5 Pigskin Puffball Mushrooms

Edible puffballs are globe-shaped fungi that are delectable when picked at the right time. Young specimens that are entirely white and firm throughout are great for eating. They can range from a couple of inches to three feet across in some varieties.

However, pigskin puffballs are hard to distinguish from the palatable species. Unlike the tasty type, this Scleroderma has a thick outer skin that might be bumpy or spotted. Although the flesh is white when they’re very young, it quickly turns grey, black, or dark purple. 

Unfortunately, these toxic mushrooms are incredibly common. Effects of ingesting them include stomach cramps, nausea, and vomiting.
