This specimen seems to be mostly immature yet, but still mature enough to get to a species easily. The peridium stains pinkish to reddish when bruised or cut (but only the peridium). Species goes through several color changes on its way to maturity: white, off-white, yellowish-white, yellow-buff, buff, brown, cinnamon-brown. According to Field Guide to North American Truffles your spore measurements are perfectly in accord: 5.5-8 × 3-4.5 microns. When slightly more mature, the gleba especially near the peridium, will stain a curious reddish-blue color, i.e. vinicolor, or wine-colored. One of the most common of our Cascades Rhizopogons.
