Here we see two aged Boletus regineus, Common Name: Queen Bolete
We have gatered this mushroom for years and have noticed a varitety of color tones and textures, depending on the habitat. We find this mushroom mainly in the fall after a somewhat dry summer.
Cap 7.0-14.0 (17) cm broad, convex, expanding to plano-convex; margin incurved, later decurved to nearly plane, not overlapping the tube layer; surface moist, more or less glabrous when young, becoming irregularly pitted or wrinkled; color at first unevenly buff-brown to pale chestnut-brown, overlain initially with a whitish bloom, in age becoming medium-brown to dark-brown, subviscid when moist; context up to 2.0 cm thick white, unchanging, firm in youth, soft at maturity, tinged pinkish-vinaceous below the cuticle, sometimes yellowish above the tube layer; odor and taste mild.
Pores up to 3/mm when young, stuffed, approximately 1/mm in age, whitish, becoming cream-colored to dull pale-yellow, eventually dingy yellowish-olive, not bluing, darkening slightly where handled; tubes up to 2.0 cm long, occasionally discoloring brownish when cut, not bluing, depressed at the stipe.
Stipe 7.0-13.0 cm long, 3.0-4.0 cm thick, solid, clavate to ventricose in youth, subclavate to equal at maturity; surface of apex reticulate, whitish, elsewhere glabrous to faintly wrinkled; context of stipe, not bluing, but darkening slightly when cut; partial veil absent.
Spores 11.5-13.5 × 3.5-4.5 µm, smooth, thin-walled, narrowly ellipsoid in face-view, hilar appendage inconspicuous, one to several guttules; spore print dull olive-brown.
Solitary to scattered in mixed hardwood/conifer forests; fruiting shortly after the fall rains.
Edible and very good.
