Indigo Milk Cap

Also known as Indigo Milky, Indigo Lactarius, Blue Lactarius, Blue Milk Mushroom

Indigo milk caps produce striking deep blue to silvery-blue mushrooms that bleed a vivid indigo latex fluid when sliced or broken. They form mycorrhizal partnerships underground with hardwood and coniferous trees, particularly oaks and pines across North America and East Asia. As the fruiting body matures, the zonate cap pales toward a greenish hue where latex bleeds and oxidizes upon exposure to air.
