Poisonous mushroom season prompts warning from East Bay Parks


The Bay Area's recent bouts of rain brought welcome relief to the drought-plagued region, but it also encourages the growth of a looming menace: poisonous mushrooms.

The East Bay Regional Park District is warning residents to be extra vigilant when roaming the outdoors this fall, especially with dogs, as the poisonous mushroom season is upon us.

The region is home to two of the world's most deadly mushrooms, the aptly named Death Cap and Western Destroying Angel, according to park officials.

"Both of these species contain amatoxins, a group of molecules that inhibit cellular metabolism in many animals," the district said in a statement. "In mammals, the liver and kidneys are typically the fist organs affected after ingestion."

The toxic mushrooms could be found in any district park with oak trees, including those in the San Ramon Valley.

The district is reminding visitors that it's illegal to pick mushrooms or any plants found in the parks.
