Identifying Your Bolete
Habitat
The literature associates it with birches in humid environments. In the boreal forest we met and photographed it in Jack Pine stands on well-drained sand. Sphagnum mosses promote the length of the stalk.
Pores and Pore Surface
Pore surface grayish to dingy brown with age, sometime with blue-greenish spots, immutable or staining brownish when bruised.
Pores circular 2-3 per mm.
Flesh
White immutable or partly reddening mainly in the stipe, sometimes bluing near the base of the stalk.
Basal Mycelium
White.
