typhlonectes: Indigo Milkcap (Lactarius indigo) Compared to other colors found in nature, true blues are pretty rare—but the indigo milk cap has just that! This vibrant mushroom gets it color from a pigment that is a derivative of guaiazulene, a dark blue crystalline hydrocarbon. You would think that its blueness is a marker for toxicity, but the mushroom is actually edible—although its color fades to a grayish hue when it’s cooked. photograph by Dan Molter via: American Museum of Natural History -- source link
