Morel vs False Morel — How to Tell the Difference

Morel Vs False Morel

It is spring in North America as I write this, and we are in the middle of morel hunting season.  Morels are delicious, and they are one of the safer mushrooms for which to forage.  But there is one thing that you must be aware of if you go hunting for morels. If you want to stay safe, you must learn how to differentiate between a true morel vs false morel.

What Is a False Morel?

False morels are closely related to true morels; they are part of the same genus — Morchella.

True morels tend to grow in the spring, under hardwood trees, especially ash and elms. See our guide on How to Find Morel Mushrooms for more morel-hunting tips and details.

False morels grow at the same time, and in the same areas, which means that if you are looking for morels, there is a pretty good chance that you will come across false morels in your search.

At one time, false morels were considered edible.  While many people have eaten false morels without suffering any ill effects, others have developed symptoms of mushroom poisoning.

Cooking them alleviate the toxicity in most species, but recent evidence indicates that there may be long-term health risks with false morel species.

These risks are most closely associated with two species of false morels: Gyromitra Esculenta and Gyromitra Ambigua.  Many mushroom hunters in Europe consider false morels outside of those two species to be edible once cooked.

That said, unless you are an expert, it is best to avoid all false morels.

Note that, if eaten raw, even true morels can cause minor stomach upset, so never eat a morel of any type without cooking it first.

How to Tell the Difference Between a Morel vs False Morel?

Note, if you are not familiar with morels, be sure to run your finds by an expert before eating them.  The North American Mycological Association (NAMA) has local chapters across North America and is a good place to find people in your area who are knowledgeable about wild mushrooms.

There are five key differences between true morels and false morels:

1: Look at the Texture of the Caps

True morels have pits and ridges in a honeycomb pattern.  False morels will have wavy, folded caps.

2: Are the Caps Hollow?

A true morel will be completely hollow inside, whereas a false morel will have cottony fibers, or may even be completely solid.

If you wince at the thought of cutting your beautiful morels, don’t.  Slugs and other critters often crawl up into the caps, so you will want to cut them in half anyway to clean the caps out.

3: Confirm that the Stems Connect At the Bottom of the Cap

In a true morel, the stem will join at or near the bottom of the cap, whereas in False morels, the stems will join at the top of the cap.  The cap will look almost like a rumpled skirt hanging from the top of the stem.

4: Are Your Morels Symmetrical?

A true morel will almost always have a nice symmetrical shape to it, whereas false morels have a wavy, uneven look.  Bulges and folds will stick out, and the false morel may even look like someone stepped on it.

5: Run a Spore Test

While it is not convenient, the surest way to tell a true morel from a false morel is to run a spore test.

True morels have light, cream-colored spores.  False morels have dark, almost black spores.

To run a spore test, place your morel on a piece of paper and put a bowl over it to keep any breeze from hitting it.

Leave the morel alone for a few hours, and remove the bowl.

If your mushroom is a true morel, you will see light-colored spores on the paper; if it’s a false morel, you’ll see dark, peppery spores on the paper.

Conclusion

Morels are one of nature’s culinary delights.  And once you learn about the characteristics of false morels, it s easy to avoid the bad ones.

If you follow the tips in this article, you will reduce the risk of mishaps.  But remember, you always take risks when foraging for mushrooms.  Be sure to show your morels to an experienced mushroom forager before eating them if you haven’t been morel-hunting before.
