Popular golden oyster mushrooms now invading Michigan forests

New study shows impacts to native mushroom species

What started as a fun and tasty culinary trend – growing exotic mushrooms at home from a simple storebought or online kit – has become another threat to Michigan’s natural resources.

A recent article published in The Conversation describes U.S. Forest Service researchers’ findings regarding the impact of golden oyster mushrooms (Pleurotus citrinopileatus) on Wisconsin forests.

Fungal ecologist Aishwarya Veerabahu stands beside a patch of golden oyster mushrooms growing on a stump in a Wisconsin forest.Native to Asian and Russian hardwood forests, these imported mushrooms are now growing in the wild in areas of the Midwest, including Michigan’s southern Lower Peninsula.

Golden oyster mushrooms, known for their bright yellow caps and nutty flavor, are featured on restaurant menus and in cooking videos. The mushrooms became popular among DIY enthusiasts with the introduction of grow kits in the early 2000s. By 2010, they began appearing in U.S. forests.

According to Aishwarya Veerabahu, a graduate student in the Department of Botany at the University of Wisconsin-Madison, “No one knows exactly how golden oyster mushrooms escaped into the wild, whether from a grow kit, a commercial mushroom farm or outdoor logs inoculated with golden oysters – a home-cultivation technique.”

To assist with research efforts, Michiganders are encouraged to report any sightings of golden oyster mushrooms in the wild. Observations can be recorded at iNaturalist.org.

Why be concerned?

Veerabahu and colleagues sampled fungal communities in forests around Madison, Wisconsin, and determined that in logs colonized by golden oyster mushrooms, only half the expected diversity of native fungal species was present.

“Fungi are sources of revolutionary medicines, including antibiotics like penicillin, cholesterol medication and organ transplant stabilizers,” said Veerabahu. “The value of undiscovered, potentially useful chemicals can be lost when invasive species push others out.”

What can be done?

Veerabahu recommends that people consider refraining from using golden oyster mushroom grow kits to prevent any new introductions.

“For people who make a living selling these mushrooms, consider adding a note that this species is invasive and should be cultivated indoors and not composted,” she said. “If you enjoy growing mushrooms at home, try cultivating safe, native species that you have [lawfully] collected in your region.”

New species are often introduced by people long before the species’ invasive qualities are known. To avoid introducing or spreading species that may be invasive, never release pets, aquarium plants or other species into the wild, choose native species for gardening, and keep exotic plants – and fungi – indoors.

My Life, My Quit program launches mobile app
  to help Michigan youth quit tobacco, vapes

LANSING, Mich – Youth in Michigan now have a new way to access free help to quit using tobacco and nicotine products, including e-cigarettes/vapes. The My Life, My Quit™ program has launched a mobile app, making it easy for teens to get confidential support from their smartphones.                  

“This new app will meet teens where they are with tools that support quitting tobacco products,” said Dr. Natasha Bagdasarian, chief medical executive. “We are grateful My Life. My Quit. worked with young adults to update their programming and are excited to promote this new option to youth in Michigan.”

As part of an effort to help young Michiganders quit tobacco, MDHHS contracts with the My Life, My Quit program. This free, evidence-based, service is designed specifically for youth who want to quit using tobacco and e-cigarette products. It offers live text and phone coaching, interactive content and personalized quit plans. The new app was developed in response to feedback from teen users and has been created to improve accessibility and expand engagement.

The app includes features like:

  • Real time chat with a quit coach.
  • Reminders and motivational messages.
  • Progress training and interactive quit planning tools.
  • Seamless connection to the full My Life, My Quit program across devices.

The app is available for download from Google Play and Apple App stores.

Youth and young adults can continue to enroll in the program by visiting MyLifeMyQuit.org or by texting “Start My Quit” to 36072.

According to the 2023 Michigan Youth Tobacco Survey, 13.2% of respondents reported current use of any tobacco product. The most common type of tobacco product used were e-cigarettes with 11.1% of youth reporting that they had used an e-cigarette in the last 30 days.

MDHHS reminds Michigan residents there are numerous benefits to quitting tobacco including financial savings, better health and more time spent with loved ones. As it can take several attempts to quit for good, tobacco users are encouraged not to give up after a failed attempt.

Four weeks to 2025 Mackinac Bridge Walk

ST. IGNACE, Mich. – For the safety and convenience of all those participating in the 2025 Mackinac Bridge Walk, the Mackinac Bridge Authority (MBA) will again start the event from both ends of the bridge, at Bridge View Park in St. Ignace and the Jamet Street ramp in Mackinaw City.

 

Starting the walk in both cities, as it has been since 2018, eliminates the need for busing and offers additional options for participants.

 

Additionally, due to its success in 2024, the walk will begin on the north end of the bridge from Bridge View Park on the west side of I-75 rather than at the MBA administration building. As most participants who start in St. Ignace already park at Bridge View Park, starting the walk from that side reduces the number of people crossing the interstate before the event begins. Participants who park on the east side of I-75 will be guided across the road before and after walking the bridge.

 

“These changes to the Annual Bridge Walk format we’ve made over the past several years have made it safer and easier for everyone to participate in this beloved event,” said MBA Bridge Director Kim Nowack.

 

A video posted on the MBA website at www.MackinacBridge.org/Walk explains the bridge walk schedule and choices people have whether they start from the north or south ends of the bridge.

 

Walkers essentially have three main options:

  • Starting from either end of the bridge and walking toward the center, turning around at the midpoint and returning to the city they started from, where their transportation is located. The turnaround points will move toward the ends of the bridge beginning at 10 a.m. but walkers can walk at least a portion of the bridge if they start by 11:30 a.m. Walkers must be on the side of the bridge they wish to return to before 10 a.m.
  • Walking the entire length of the bridge starting from either end. Those who choose this option must reach the midpoint before 10 a.m. or they will be turned back. Anyone who walks the entire bridge must arrange their own transportation back to the side they started once the bridge reopens to public traffic at noon.
  • Crossing the bridge, starting from either end, and then turning around and walking back to the side they started from. In this option, walkers will need to cross the midpoint on their return trip by 10 a.m. or they will be turned back and need to find their own transportation back across the bridge after it reopens at noon.

 

As with the last several events, because walkers can start from either end of the bridge when they arrive, there will be no buses transporting participants across the bridge. Participants must plan accordingly to ensure they end their walk on the same side of the bridge as their transportation. The MBA does not provide any shuttle service after the walk and cannot guarantee outside shuttle services will be offered.

 

The bridge will again be closed to public traffic during the 2025 walk, from 6:30 a.m. to noon on Labor Day, Sept. 1, based on recommendations from the Michigan State Police and U.S. Department of Homeland Security. Emergency vehicles will still be permitted to cross the bridge, but no public vehicles will be allowed until the walk concludes and participants are off the bridge.

 

The bridge walk has been an annual event since 1958, with the exception of 2020. The 2024 walk will be the 67th event. Between 20,000 and 35,000 people have participated in recent years; 30,000 participated in the 2024 event.

Ice storm waterfront cleanup: EGLE recommendations, permitting requirements, and best practices for northern Michigan

As northern Michigan is recovering and rebuilding from the March 2025 ice storm, affected landowners have been interested in regaining access to their lake or stream and cleaning up their waterfront. The Michigan Department of Environment, Great Lakes, and Energy (EGLE) can help by providing guidance and information on best practices, project design advice, or through pre-application meetings when removing trees and debris from the water and shoreline.

Before removal, EGLE recommends waterfront landowners consider leaving fallen trees and limbs in the water, unless removal is absolutely required for safety, navigation, or use of the water body. Fallen trees along the shoreline and in the water provide many benefits such as cover, feeding, nesting, and basking habitat for fish, birds, turtles, and other wildlife. Shoreline woody structure can also improve fishing by attracting fish and increasing the number of fish in the area.

If removal of trees and woody debris is required, scheduling a pre-application meeting with the local EGLE District staff is a great first step to determine any regulatory requirements. In general, hand removal of woody debris that does not alter the soil, sediment, bed, or banks of the water body does not require a permit from EGLE. When removal cannot be done without soil or sediment removal/disturbance, or the use of heavy equipment, a permit is required.

EGLE recommends not driving heavy equipment into the water for removal of woody structure and debris. Removal of debris should follow the Clean and Open Method: the woody material is cut and removed within the main channel to allow the natural flow of water, without removing wood or soil within the bed or banks.

Additionally, EGLE recommends the following best management practices: 1) Remove the minimum amount of the obstruction necessary to restore navigability or alleviate flooding. 2) Properly dispose of any material removed from the lake or river in an upland (non-floodplain, non-wetland, non-bottomland) location.

If removal of trees and woody structures is not required for safety, navigation, or use of the waterbody, EGLE encourages leaving them in the water to provide habitat and shoreline protection benefits.
