Baorangia bicolor (Boletus bicolor), the "Two-colored Bolete”, has a red cap mottled yellow; yellow flesh, short yellow tubes, pores. Stipe yellow above & red below. Slowly turns blue when bruised. Mycorrhizal with oak. There may be a few different varieties of Baorangia bicolor. I’ve heard it said that Baorangia bicolor doesn’t stain blue, but the yellow pore surface can stain bright blue. The flesh, however, is slower to stain and when it does it is a comparatively pale blue color. The two-colored bolete appears mainly in summer and is a prized edible. Not everyone can tolerate eating them though. Some people may experience stomach upset and diarrhea. This bolete is mycorrhizal with oaks and other hardwoods.
