✅ Edibility Note
EDIBLE: Two-colored Bolete is a good edible with mild flavor and firm texture. The dramatic blue-staining reaction is completely normal and safe - it does NOT indicate toxicity. Some people may experience digestive upset. The striking bluing and two-toned stem (yellow/red) are diagnostic features. Always cook thoroughly.
Description
The Two-colored Bolete features a reddish to pinkish-brown cap (5-15 cm) with smooth to wrinkled surface. Pores are yellow, instantly bruising blue when touched - a dramatic reaction. The yellow stem with reddish base displays reticulation and bruises blue-green. Yellow flesh immediately stains deep blue when cut, one of the most dramatic bluing reactions among boletes. Spore print is olive-brown.
