Brief Description: [See More | Edit]

This is a medium to large bolete that is associated with various conifers. In the south it grows with loblolly and longleaf pines and in the NJ Pine Barrens it’s mycorrhizal with the pitch pine, Pinus rigida. In the latter habitat, these can be found from late July into early September, usually as single sporocaprs, sometimes in small scattered groups.

- The cap is convex, up to 7" in diameter, becoming flatter with age. Reddish-brown to brown in age, instantly bruising blackish-blue upon handling/injury. – The pore surface is yellow, instantly bruising blue and resolving brown.
- The stipe is up to 5" long, enlarging toward the base. It’s tri-color: yellow at the apex, brown in the middle and red below. In age or if handled sufficiently, the entire stipe turns brown.
In the end the entire mushroom turns brown and becomes difficult to ID. The context is pale to medium yellow, instantly turning vivid blue upon oxidation, but within a few minutes brown coloration takes over from the bottom of the stipe up.
