Unlike the Death Cap, it is a native California mushroom.īoth of these species contain amatoxins, a group of molecules that inhibit cellular metabolism in many animals. It fruits from late winter into spring, and is associated exclusively with oaks. It was accidentally introduced to North America on the roots of European cork oaks, and is now slowly colonizing the West Coast.Īmanita ocreata (the Western Destroying Angel) is a medium to large mushroom that usually has a creamy white cap, white gills, a white ring around the stem that disappears with age, and a thin white sac at the base. Though the Death Cap is mainly associated with oak trees, it has been found growing with other hardwoods. It fruits early in the fall, usually right after the first rains. Both are robust, handsome mushrooms that grow near oak trees, and both contain lethal toxins.Īmanita phalloides (the Death Cap) is a medium to large mushroom that typically has a greenish-gray cap, white gills, a white ring around the stem, and a large white sac at the base of the stem. The Bay Area is home to two of the world’s most toxic mushrooms – Amanita phalloides (the Death Cap) and Amanita ocreata (the Western Destroying Angel). Sprouting in an array of dazzling colors, these fungal fruitbodies can be beautiful – but some of them are deadly poisonous. After the first fall rains, the East Bay hills come alive with mushrooms.
