If you’re familiar with morel mushrooms, you might have come across their “fake” counterpart. But what exactly are these imposters, and why should you be cautious? Whether you’re a seasoned forager or a curious beginner, it’s essential to be aware of the various look-alikes known as false morels. Let’s dive into all you need to know about these intriguing fungi.
What Are False Morels?
The term “false morel” encompasses several species, including Gyromitra esculenta (also known as the beefsteak mushroom), Gyromitra caroliniana, and others found in the Verpa and Helvella genera. These mushrooms are often mistaken for the edible delicacies belonging to the Morchella genus (true morels).
It’s worth noting that some false morels are poisonous due to the presence of monomethyl hydrazine (MMH), a chemical compound. MMH can cause symptoms such as vomiting, dizziness, diarrhea, and in severe cases, even death. Additionally, MMH is suspected to be carcinogenic. So why do people still consume these mushrooms?
Surprisingly, certain false morels, such as Gyromitra esculenta, are considered delicacies in parts of the United States and Scandinavia. In Finland, you can even buy them with preparation instructions. However, one significant risk lies in the varying levels of MMH found in different species and locations. No one can determine the exact toxicity of any false morel. Therefore, caution should always prevail.
False Morel Mushroom Facts
To better understand false morels, let’s explore some essential facts about them:
- Most gyromitra species appear in spring and summer, growing directly on the ground. While some may be found on wood or later in the year, they are unlikely to be mistaken for true morels.
- False morel caps are typically brown or reddish-brown, occasionally yellow, while their stems range from white to tan.
- These mushrooms are considered saprotrophs, feeding on dead and decaying organic matter. Some experts propose that they may also form a symbiotic relationship with trees, known as mycorrhiza.
- Similar to true morels, false morels often thrive in areas where the forest floor has been disturbed. Look for them near washes, rivulets, man-made ground disturbances, or roadsides.
- Common false morel species include Gyromitra esculenta, Gyromitra caroliniana, Gyromitra infula, Verpa bohemica, and Verpa conica.
- It’s important to note that some edible mushrooms share common names with false morels, such as beefsteaks and calf’s brain. Be sure to educate yourself and avoid any confusion during foraging.
How to Identify the False Morel Mushroom
Distinguishing a true morel from a false one requires careful observation. Keep the following pointers in mind:
- Cap shape: False morels have wavy or lobed caps that appear bulging outwards. In contrast, true morels boast uniformly shaped caps with pits or ridges resembling honeycomb patterns.
- Cap attachment: The cap of a false mushroom hangs freely from the stem, while a true morel usually has a cap attached to the stem, although exceptions exist.
- Hollow vs. filled: If you slice open an edible morel from top to bottom, you’ll find it hollow inside. In contrast, a non-edible one will contain wispy cotton-like fibers or tissue chunks.

Always seek guidance from a local expert if you’re inexperienced or uncertain. Never rely solely on internet images to determine the edibility of mushrooms. This applies not only to morels, but to all mushroom varieties. If you experience sickness or dizziness after consuming what you thought was an edible morel, seek immediate help.
Who Eats These Mushrooms… and Why?
In some parts of Europe, the United States, and even Helsinki, Finland, false morels are sold and consumed. However, their preparation can vary. Some false morels require boiling two to three times to remove toxins before they can be safely eaten. Boiling reduces the toxin levels and renders the mushrooms edible. This boiling practice has been used for centuries to ensure safety.
Nevertheless, studies suggest that MMH is a cumulative toxin, meaning its levels can build up in the body after repeated consumption, leading to illness or even death. Hence, it’s crucial to weigh the risks before consuming false morels. Although many people have consumed them for years without issues, the lack of precise toxicity information prompts caution. The ultimate choice is yours, but thorough research is essential before making a decision.

While false morels may seem fascinating, it’s wise to avoid them altogether to mitigate potential risks. Remember, accurate identification and expert advice are crucial when it comes to foraging mushrooms. Stay safe and happy exploring!
