Why do most plants die in salted soil, while this incredible fungus thrives in it? 🍄🧂

In this Deep Dive, we uncover the strange life of Agaricus bernardii—the salt-loving mushroom that has evolved to follow human infrastructure. Originally a seaside dweller, this hardy mushroom now tracks the salt trucks along our winter highways, growing where nothing else can.

In this episode, you’ll learn:

• The Supermarket Secret: How this rugged mushroom is related to the famous Portobello and Button mushrooms.

• Urban Camouflage: How to distinguish it from the "Pavement Mushroom" (Agaricus bitorquis) that can literally break through asphalt.

• The Toxic Look-Alike: How to spot the dangerous "Yellow Stainer" (Agaricus xanthodermus) that will send you to the hospital.

• The "Lead Sponge" Danger: Why you can eat this mushroom technically, but you definitely shouldn't if it's growing near a busy road.

Whether you are an urban forager, a biology nerd, or just curious about the secret nature hidden in your city, this episode changes how you look at the sidewalk forever.
