NMSU researcher: toxic mushrooms growing around campus, Las Cruces

LAS CRUCES, New Mexico (KVIA) -- A NMSU researcher is warning the campus and Las Cruces community not to eat or pick mushrooms that have been growing around the city and the campus.
The mushrooms are members of a fungal group called Chlorophyllum molybdites, also known as false parasol, says Soum Sanogo, a professor in NMSU’s Department of Entomology, Plant Pathology and Weed Science in the College of Agricultural, Consumer and Environmental Sciences.
False parasol commonly grows in southern New Mexico and other regions in the United States, including the Southwest, during the fall as the season transitions from summer to winter.
Sanogo says the mushrooms are sprouting across Las Cruces and New Mexico State University, in part due to recent rains and warm temperatures. The flourishing fungi may look like harmless mushrooms you might buy at a grocery store; Sanogo is warning humans and animals alike not to pick or eat them.
“These mushrooms are harmful to people when consumed,” Sanogo said. “These are not the typical death-causing mushrooms, but when consumed they can ‘teach you a lesson’ as they may cause symptoms that include perspiration, nausea, vomiting, abdominal pain and diarrhea.”
He added, “If a significant ingestion occurs, especially if one is experiencing symptoms, it may be advisable to go to the emergency room for examination and possible treatment.”
Sanogo says that in its early stages, the false parasol mushrooms can resemble a button mushroom. However, as these mushrooms mature, the underside of the cap turns greenish.
“Many types of mushrooms appear in the autumn,” Sanogo said. “It is important for people to refrain from consuming any mushrooms they find in their backyards, parks, or along hiking trails. Mushrooms do play an essential role in our environment as recyclers and as contributors to soil health.”
Sanogo advises pet owners to remove and dispose of the mushrooms to prevent ingestion, as they can be harmful to pets.
