Single fb growing in mixed woods. Cap 10.5 cm across. Stem, pores and flesh all stain dark blue rapidly. Did not notice the cap surface staining significantly. Could not get a spore print but spores were brown in KOH under the scope. Spores ~13.3-15.9(16.8) X 4.0-6.0 microns, fusoid. Boletus oliveisporus seems pretty close.
