Bluing Bolete - Gyroporus cyanescens
I had barely brushed up against this mushroom when it started to bruise blue. Once I cut into the flesh, it immediately stained a dark blue-purple color. The cap was tan-yellowish in color, rough and scaly, and was approximately 8 cm in diameter. The stem was thick and had similar coloration as the cap. Pore surface was pale yellow.

Habitat: deciduous forest
