The False “Beefsteak” Morel (Gyromitra esculenta)

Article by Bruce Pandoff

It is mushroom season in many parts of the US and morels are some of the most prized popping up at this time. They are considered easy to identify but there are some potentially deadly lookalikes growing in the forest and making their entrance at the same time. The false morel, commonly known as Beefsteak Morel, or Gyromitra esculenta is one of these such poisonous mushrooms and is a common mushroom for beginning mycophagists (mushroom hunters) to poison themselves with.

Before consuming any mushroom I highly recommend seeking the in person tutelage of an expert in the field of mycology or otherwise foraging expert. Look for groups and clubs that often are lead by these experts. Check bulletin boards at libraries, civic centers, college universities, and local co-op stores for such postings by these groups seeking members. If all else fails, search the internet for a local group. I am adamant about the seeking of experts and will rarely teach about edible mushrooms except for a very small selection for the simple fact that there are expert mycologist that poison themselves each year where as I gladly teach others about plants as this phenomenon with mycologists rarely happens with botanists. As you progress always keep in mind, there are old mycophagist and there are brave mycophagist, but there are no old brave mycophagist. Often how we find out if a mushroom is poisonous is due to those brave souls finding out for us and the mycological community learning from the toxicology report. Venture forth carefully.

Here is the poisonous lookalike of the prized morel, Gyromitra esculenta. It often grows under conifers such as balsam, pine and spruce. Fruiting bodies (mushrooms) may be found in spring but summer and fall are the predominate fruiting periods.

The mushroom from a distance or to the beginner may look like a morel, but upon closer inspection key identifying features will be revealed. The surface is not truly pitted, it is wrinkled, folded, and convoluted where as true morels will be pitted like a sponge.

The stem may be white, cream, or have a slight yellow tint. When cut open the stem is solid though may have air pockets. A true morel will be hollow all the way through.

It had previously been thought that these mushrooms could be parboiled, the water discarded, to be made edible but recent evidence indicates that this is in no way a reliable method of removing all the poisons. This species and other false morels cause poisoning through a compound known as Monomethylhydrazine which is found in jet fuel. When poisoned, the victim’s symptoms will be delayed anywhere from six to twelve hours. Eventually, fatigue, headache, abdominal pain, and occasionally watery diarrhea may occur. In more extreme cases, liver damage, delirium, and occasionally death will occur. There are no antidotes as of yet. There are plenty of other edibles to learn out that do not requiring doctoring to be made edible making Gyromitra not worthwhile.

Radical Mycology

Peter McCoy is seeking contributions for a new book on the current state of the field of mycology. In short, the book will be a user friendly guide to the entire fungal kingdom, exploring its many ecological roles as well as the ways that humans can cultivate and interact with the various forms of fungi found around the world. The book will also highlight the various aspects of mycology that are “cutting edge,” in need of citizen scientist contribution, or are otherwise exciting for those new to the field. The book will be both entertaining as well as technical and instructional. He is looking for information, suggestions, and/or contributions in the following areas:

  • Current or future fields of research on mychorriza that are exciting, pressing, or considered a “big unknown.”
  • Common, interesting, popular, edible, medicinal, or utilitarian fungi found in your part of the world. Names, photographs, and information on the best practices for harvesting, identifying, and using them as well as when and where to find them.
  • Information on local traditional uses of fungi and lichens in your part of the world (ethnomycology)

He is also looking to interview people that have knowledge in these areas. Contact Peter at to lend a hand.

Important guidlines to follow when collecting and eating wild mushrooms…

There are many species of delicious wild mushrooms which grow in our area, and learning to find and enjoy these gifts is satisfying on many levels. Caution should be exercised as there are many species that are not considered edible and may cause various levels of discomfort if eaten, and a handful that contain potent toxins that can cause permanent organ damage, or even death. For your safety and enjoyment, please follow these guidelines, and always remember: “when in doubt, throw it out!”.

  • Every mushroom you plan to eat should be ACCURATELY IDENTIFIED as an edible species.
    Despite folklore to the contrary, there are no simple guidelines which will separate edibles from other species. You must assume the responsibility to identify all wild mushrooms you collect to eat with 100% confidence. Many edible species have toxic look-alikes; learn what these are, and don’t rely only on photographs or drawings!
  • Never eat raw mushrooms.
    This applies to all mushrooms: improved digestibility, flavor, available nutrition and the elimination of some potentially harmful substances all result from thorough cooking. However, be aware that cooking will not eliminate all types of toxins and will not make poisonous mushrooms edible.
  • When trying a mushroom species for the first time…
    Eat only ‘two’ cooked teaspoons of one species, and wait at least 24 hours before eating any more of that species or trying another new species. A few people have an allergy to one particular mushroom species, just as some people are allergic to shrimp, wheat, dairy or other foods. If you are eating new species for the first time, and you eat more than one species and have a reaction you won¹t know which species you are allergic to. So sample new species one at a time (one per day maximum), and for the first sample, limit to two teaspoons. Keep a whole, uncooked sample of the mushroom species in your refrigerator in case the identification needs to be confirmed later.
  • Do not consume alcohol when trying a mushroom for the first time.
    Wait until you are sure you are not allergic to a particular species before having it with wine or beer. When consuming a new mushroom species, the presence of alcohol may produce stronger allergic reactions. Also, one species of the genus Coprinus (the shaggy manes) reacts with alcohol resulting in uncomfortable symptoms. Before eating any shaggy mane, learn to identify the one which causes this reaction, and its look-alikes.
  • Only eat fresh mushrooms.
    You wouldn’t eat moldy or rotting produce from the grocery store -the same should be true for wild mushrooms.
  • Do not eat fungi growing on ornamental trees. In some cases toxins in the wood may be incorporated into the fungal tissue. (A recent instance of illness in Eugene was reported from eating Laetiporus growing on black locust).
  • Be aware of where you are collecting your edibles.
    Mushrooms can readily pick up chemicals from the environment. Never consume edible species from a lawn where fertilizers or pesticides might have been applied. Avoid collecting along busy roads or anywhere near old dump sites. Do not eat fungi growing on ornamental trees. In some cases toxins in the wood may be incorporated into the fungal tissue. A recent instance of illness in Eugene was reported from eating Laetiporus (sulphur shelf or chicken-of-the-woods) growing on black locust.

ENJOY! Having an understanding and appreciation of the variety and beauty that surrounds us in the fungal world will enrich your diet and your life!

Mushroom Picking Permits

You should always check with all the federal agencies on whose lands you may pick before the beginning of each mushroom season to find out what the latest regulations are. If you are not picking on federal lands, make sure that you have the correct type of permission from the landowner.

On CMS-sponsored forays we usually visit federal lands, and you may need a permit. Obtaining a FREE USE PERMIT from the Willamette National Forest office (downtown Eugene) or a Ranger District Office before the trip is strongly encouraged.(Click here for additional mushroom permit information)
