LANSING, Mich. – As the spring wild-foraged mushroom season gets underway, the Michigan Department of Agriculture and Rural Development (MDARD) reminds foragers that all mushroom species picked in the wild to be sold must be inspected and found safe by a certified mushroom expert. In addition, all certifications set to expire in 2020 have been extended for one year, due to a temporary suspension of mushroom certification courses.

Michigan’s Food Code requires those who sell mushroom species picked in the wild to either be certified as an approved mushroom identification expert, or to have each mushroom individually inspected and found safe by a certified mushroom expert.

“Wild mushrooms, like morels and chanterelles, help define the forests of Michigan and provide potential income streams for foragers, farmers, restaurateurs and food entrepreneurs,” said Tim Slawinski, MDARD Food and Dairy Division director. “However, if improperly identified, mushrooms can pose serious health risks. If you are purchasing wild mushrooms, you should only purchase them from a certified mushroom identification expert, as required by Michigan’s Food Code, to assure they are safe and edible.”

MDARD recognizes the certification and training course offered by Midwest American Mycological Information (MAMI). MAMI is a nonprofit, nonpartisan public organization whose mission is to provide unfettered access to accurate, up-to-date information on topics related to mycology including mushroom identification and cultivation. These certification and training courses have been suspended for 2020 due to the death of course trainer, Chris Wright, a nationally recognized mushroom expert and researcher at Michigan State University, who also served as MAMI’s executive director.

“Due to the sad and untimely passing of MAMI Executive Director Chris Wright on January 29, 2020, MAMI is not conducting certification or recertification exams during the spring of 2020,” said Dr. Greg Bonito, assistant professor of mycology at MSU’s Department of Plant, Soil and Microbial Sciences, and acting executive director of MAMI. “MAMI is working to fill the void left by this loss, and we expect certifications and recertifications to resume in 2021.” 

Those who successfully complete the course offered by MAMI are certified by MDARD and the certification is valid for five years. Certified mushroom identification experts should be prepared to show their certification cards as proof of certification, upon request. MDARD does not receive any money from MAMI for conducting the training and certification. All funds support the training program and materials.

The certification and training course offered by MAMI has been in place for five years. Certifications for those who took the course in 2015 will expire this spring and over the course of the 2020 calendar year. The expiration date for those whose certifications expire in 2020 has been extended for one year. New certification cards with the extended expiration date have been sent to all certified mushroom experts with expiring cards whose addresses were available. If your certification expires in 2020, and you did not receive an extension certification card, please contact Denise Clemens at


There are many species of edible mushrooms that grow in Michigan, but there are also toxic, poisonous species, so there is some risk involved. There are also many look-alike varieties for some wild mushrooms, including morels. These ‘look-alikes’ can cause serious illness or death when eaten, so it’s important to know how to properly identify mushrooms and to only buy mushrooms from someone who is a trained, certified mushroom identification expert.

“Please enjoy hunting for and eating your favorite wild mushrooms, but make sure you know how to properly identify them,” said Slawinski. “If you plan to sell your wild mushroom harvest, you must be a certified mushroom identification expert or have the mushrooms inspected by one; and if you operate a store or restaurant and plan to purchase mushrooms for resale to your customers, they must be purchased from an approved source and individually inspected by a certified mushroom identification expert. Finally, if you’re purchasing wild mushrooms, especially online through social media platforms, always ask for proof of certification before purchasing any mushrooms.”

Mushroom poisoning refers to harmful effects from ingestion of toxic substances present in some mushrooms, with symptoms ranging from slight gastrointestinal discomfort to death. Common symptoms associated with mushroom poisoning include vomiting, diarrhea, abdominal pain, weakness, lethargy and yellowing of the skin or eyes (jaundice). Mushroom poisoning is usually the result of ingestion of wild mushrooms after misidentification of a toxic mushroom as an edible species. The most common reason for this misidentification is close resemblance in terms of color and general morphology of some toxic mushroom species with edible species.

If you suspect mushroom poisoning, seek immediate medical assistance, and call the Michigan Poison Control Center at 1-800-222-1222. For information about mushroom identification training and certification, or to view a list of certified mushroom identification experts in Michigan, please visit MAMI’s website at To report potentially illegal sales of wild-foraged mushrooms, contact MDARD at 800-292-3939 or send an e-mail to You may also file a food safety complaint online through the MDARD online complaint form.

The search for a cleaner way to clean takes researchers to the world of rot
(Jan. 6, 2018)

Mushrooms are capable of synthesizing an amazing arsenal of chemical compounds. Among these are enzymes that a Danish company adapts for use in detergent. The enzymes break down dirt using less water and function at lower temperatures, so washing requires less energy. The enzymes are increasingly incorporated into common brands, replacing some of the otherwise petroleum-based detergents. read more…

Will Snakes Disappear From Earth? Lethal Fungal Disease Spreading Fast, Hits Europe
(Dec. 22, 2017)

What would the world look like without snakes? More rats for one thing. Although many find them distasteful, snakes play important roles in many ecosystems, and concern for their welfare is growing. Snake populations worldwide are threatened by a fungal disease that attacks their skin. The infection causes severe itching, skin lesions, and behavior changes that leave them vulnerable to predation. Many species of snakes in the US have already experienced a sharp decline in numbers. Now, the disease has been found in Europe, and it could become a global epidemic. read more…

Studies reveal which gene mutations allow stem rust fungus to infect wheat crops
(Dec. 21, 2017)

Wheat stem rust is a fungal disease that can decimate entire fields, spread rapidly, and easily outfox attempts at control. The latest concerns surround the strain labeled Ug99, which is marching across Africa and the Middle East, and which can infect wheat varieties that were previously considered resistant. Scientists are focusing on what makes this fungus so adaptable. They have discovered two fungal genes which trigger the plants’ immune response. When these genes are modified, as they are in the Ugg99 strain, the plant does not recognize them and is susceptible to infection. Breeders hope that they can deploy this knowledge to create resistant wheat strains that stay one step ahead of the rust and prevent a global crash of the wheat supply. read more…

Bugs may be causing a common crop mold to produce a deadly toxin
(Dec. 19, 2017)

A grayish-green powdery rot, transforms the tips of corn ears into withered skeletons. More than an unpleasant image, Aspergillus flavus can also be dangerous. Some strains of this fungus produce aflatoxin, a poison that causes both serious illnesses and economic losses. Now, scientists at Cornell University are unraveling the interactions between these toxic fungi, and the insects that live nearby. In the presence of fruit flies, toxic strains grew more vigorously and produced more toxins, suggesting that the insects either help the fungus, or spur it to protect itself. These relationships are complex, but understanding them gives farmers precise and powerful tools for managing their fields and protecting the public. read more…

Gov. Snyder Vetoes Bill to End Morel Mushroom Training, Cites Poisonings
(Jan. 9, 2017)

Morel hunters must still be licensed in order to sell their finds. Governor Snyder vetoed a bill that would have exempted those who sell morels from the mandatory training and certification process. Proponents of the bill say that morels are comparatively easy to recognize and provide an additional source of income for many amateurs. However, the numerous incidents in which people have been poisoned by eating mushrooms that they believed to be morels prevented the Governor from signing the bill.

Magic Mushroom Drug Psilocybin Helps Cancer Patients Chill Out
(Dec. 1, 2016)

Doctors are getting better and better at treating physical illnesses, and now a mushroom may help us treat the accompanying disorders that we can’t see. Psilocybin, the mind-altering drug contained in so called “magic mushrooms,” has been shown in several studies to reduce depression and anxiety in patients suffering from terminal cancer. Participants in one study received a single dose of psilocybin and reported significant increases in wellbeing which lasted long after the drug left their systems. This is promising news since depression and anxiety disorders affect nearly half of all cancer patients. Studies like this one provide hope that we will soon be able to treat not only the cancer itself, but the psychological wounds it leaves behind.  read more…

Faux Leather Made From Reishi Mushrooms
(Nov. 16, 2016)

The uses for fungi are ever expanding. One company has devised a technique to turn mycelium into a convincing substitute for leather. MycoWorks manipulates the growth patterns of Reishi mushrooms, causing them to form large, flexible sheets that are remarkably similar to real leather. The material is durable, eco-friendly and an appealing alternative for those who are concerned about animal welfare. Perhaps in a few years we will be growing our bags and briefcases rather than sewing them. read more…
