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.
Hypomyces chrysospermus is a parasitic ascomycete fungus that infects fungi of the genus Russula, turning their fruiting bodies yellow to orange. In St. Petersburg and Leningrad Oblast, it has been found on various species of Russula, with a frequency of infection ranging from 1-10%. The fungus is widely distributed in north-western Russia, where it typically fruits in late summer to early autumn, often in association with coniferous and mixed forests.
