How poisonous are morels?

True morels are mildly toxic if you eat them in large quantities, and some people have allergic reactions, so it’s best to eat in moderation if it’s your first time trying them. Also, morels shouldn’t be eaten raw since cooking them takes away some of the toxic substances. 

False Morels are a type of mushroom that looks very similar to true morels but is considered poisonous. Unlike true morels, false morels have hollow interiors and longer stems. While there are instances of people eating false morels without any ill effects, most experts recommend avoiding them to be safe. 

Differences between “True Morels” and “False Morels”

The best way t tell if you have a true morel or a false morel is by cutting it open to check if it’s hollow inside or not. A hollow morel means it’s a true morel, whereas false morels have a cotton material inside. 

There is also a difference in the stems as true morels have stems that attach at the bottom of the cap. However, false morels have stems that join at the top of the cap and fold over the stem like a skirt. 

Both true and false morels like to grow in similar conditions so the same areas can have a mixture of both kinds. However, false morels can grow into the summer and early fall, but true morels tend to only grow during the late spring.

How to stop mushrooms growing in your yard

If you want to prevent your dog from eating the wrong kind of mushrooms, the bests step is to remove and prevent mushrooms from growing on your lawn. Here are some things to incorporate into how you care for your property to ensure your dog stays safe. 


Mushrooms thrive in moisture, so having standing water in your yard after it rains will facilitate their growth. You can try using rain barrels to collect rainwater from your roof, preventing it from collecting on your lawn or dig an underground drain to redirect water off your property. 

Remove shade

Mushrooms love shady areas, so you could try pruning the trees on your property to allow more sunlight onto your lawn. The extra sunlight will also help dry your yard after a rainfall.

Remove organic materials

Not racking fallen leaves or grass clippings from mowing your lawn will create a layer of decaying organic matter that mushrooms will love to grow in. Making sure that you remove any organic material from your yard helps keep mushrooms from growing and makes it easier to spot any that might pop up.

Mow Regularly

Mowing your lawn regularly will keep moisture from staying in the soil since shorter grass dries faster. Just be sure to remove any mushrooms already growing before mowing your property to prevent spores from spreading.
