In California, Poisonous Death Cap Mushrooms Are The Forager’s Bane

Quoted: The death caps arrived in California from Europe as early as the 1930s and ’40s, says Anne Pringle, a biologist at the University of Wisconsin, Madison. She discovered this timeline through genetic testing of death cap samples collected in California during this era. She says death caps likely sneaked into California from Europe attached to the roots of imported plants — and they got really comfortable, spreading all over the state.
