An invasive mushroom is spreading across southern Wisconsin and North America, severely reducing the biodiversity of other fungi, according to a new study led by a University of Wisconsin-Madison researcher.
Aishwarya Veerabahu and a team of mycologists from UW-Madison and USDA Forest Service studied the edible golden oyster mushroom, which was brought from East Asia to the United States by mushroom cultivators in recent decades and has spread in the wild.
