Chrome-Footed Bolete

The chrome-footed bolete (Boletus chrysenteron) is a species of mushroom in the family Boletaceae, widely distributed in deciduous and mixed forests of Europe and North America. Like other boletes, it produces a fleshy fruiting body with a sponge-like pore surface on the underside of the cap rather than the gills typical of most mushrooms. The cap surface of Boletus chrysenteron is dry, olive-brown to reddish-brown, and frequently develops irregular cracks revealing a reddish layer beneath the cuticle — a characteristic feature that aids identification. The stipe is typically pale above with reddish tints below. The flesh stains blue-green when cut or bruised, a reaction caused by oxidation of pulvinic acid derivatives. This species forms ectomycorrhizal associations with deciduous trees, particularly oaks and beeches, playing an important role in forest nutrient cycling. Boletus chrysenteron is considered edible but is of modest culinary value compared to premium edible boletes such as the porcini. Its flesh is often soft and prone to insect infestation. The species is common throughout its range and has no significant conservation concerns.
