A Delicious But Invasive Mushroom Could Affect Fungal Diversity

It all started harmlessly enough: People bought kits to grow mushrooms at home. But then, scientists in the upper Midwest noticed something strange. The golden oyster mushroom, which is not native to the United States, was thriving in local forests. Those homegrown mushrooms escaped our basements into the wild. Fungal ecologist Aishwarya Veerabahu joins Host Ira Flatow to discuss what impact these invasive mushrooms might have on the ecosystem.

Plus, nightshade expert Sandra Knapp describes the evolution of the potato plant, and how a lucky crossbreeding millions of years ago may have given rise to the starchy tubers we eat today.

Guests:
Aishwarya Veerabahu is a fungal ecologist and PhD candidate at the University of Wisconsin-Madison.
Dr. Sandra Knapp is a Merit Researcher at the Natural History Museum in London.
