Extract from Wikipedia article: The bolete eater, Hypomyces chrysospermus, is a parasitic ascomycete fungus that grows on bolete mushrooms, turning the afflicted host a whitish, golden yellow, or tan color. It is found in Eurasia and North America, as well as southwest Western Australia. Unlike the related Lobster mushroom, H. lactifluorum, the bolete eater and its afflicted host mushrooms are inedible.
