EDIBLE: Bluing Bolete is a good edible mushroom with firm texture and mild flavor. The blue-staining reaction is normal and safe - this is NOT an indication of toxicity. Cook thoroughly before eating. The bluing helps distinguish it from non-bluing species like B. edulis.
The Bluing Bolete displays a brown to reddish-brown cap (5-15 cm) with smooth surface. Pores are yellow to olive-yellow, slowly bruising blue-green when handled - a diagnostic feature. The yellowish stem shows reticulation and also bruises blue. White to pale yellow flesh stains blue when cut, especially near pore surface. This bluing reaction distinguishes it from similar species. Spore print is olive-brown.

Always verify identification to avoid these similar species. The differentiator is the point — learn the one or two tells that separate them:
white pores, no bluing reaction
more dramatic bluing, different range
pink pores, bitter, no blue
bruises blue very strongly
