These were growing on the ground(mostly buried) under conifers @ ~ 7000 ft. Caps up to 18.5 cm across. Caps darkening slowly to blackish. Gills whitish to creamy then blackish with age and drying. Trace of reddish noted on edges of largest specimen. Stems seemed to bruise light pinkish red but eventually darkening. Spore print white. Spores ~ 7.6-9.3(10.0) X 6.0-7.0 microns. Somewhat thinly warted and with some short reticulations. Q(ave) = 1.34. Taste mild. Did not detect a strong odor. Russula adusta seems to fit for the most part although there is little record of them this far south in the Sierras.
