Baorangia bicolor, commonly known as the Two-colored Bolete, is a medium to large bolete easily recognised by its vivid contrast of colours: a smooth, red to reddish-pink cap, bright yellow pores, and a yellow stem often flushed with red. The flesh is pale yellow and slowly bruises blue when cut or handled, which is a feature that helps distinguish it from similar species that bruise more rapidly and intensely. It typically grows in hardwood forests, especially near oaks.

Cap convex when young, gradually becoming broadly convex or nearly flat as it matures. The surface is dry and finely velvety when very young, but it soon becomes smooth and bald. At maturity, the texture resembles soft leather, and in older specimens, the surface may develop fine cracks. The colour is usually deep pinkish red to dark brick red, often fading to a lighter reddish or pinkish tone with age. The flesh is pale yellow. Pore surface usually slightly decurrent, running a short distance down the stem, especially in young specimens. It starts out bright yellow, gradually becoming orangish and then dull olive yellow with age, and occasionally reddish in older specimens. When bruised, the pores typically stain blue, often promptly but sometimes more slowly. Stem yellow near the apex, with the lower two-thirds showing red to rosy red colouration. When injured, it bruises blue very slowly and may show little to no colour change in some cases. The stem is solid inside, lacking a ring or any trace of a partial veil. The flesh is deep yellow. Spore print olive-brown.

Microscopic Features: Spores measuring 9–11 × 3.5–5 µm, subfusiform (somewhat spindle-shaped), smooth, and hyaline to yellow or golden in potassium hydroxide (KOH).

Synonyms: Boletus bicolor is an older name for Baorangia bicolor.
