Extract from Wikipedia article: Gyroporus cyanescens, commonly known as the bluing bolete or the cornflower bolete, is a species of bolete fungus in the family Gyroporaceae. First described from France in 1788, the species is found in Asia, Australia, Europe, and eastern North America, where it grows on the ground in coniferous and mixed forests.
Gyroporus cyanescens is a species of bolete fungus that grows in association with trees, particularly conifers. In St. Petersburg and Leningrad Oblast, it has been found in pine forests, often fruiting in late summer to early fall. In north-western Russia, the species is relatively common, occurring in similar habitats, including sandy soils and heathlands with pine and birch trees. The fungus produces medium-sized to large fruitbodies with a blue-gray to gray-brown cap and white to yellowish pores, turning blue-green when bruised.
