X. zelleri and X. atropurpureus both formerly Boletus zelleri.

From mushroomexpert.com: "both appear to be mycorrhizal with conifers, and their physical features overlap. The cap of atropurpureus, when young, is often tightly wrinkled, and this may be the most useable separator. Several other West-Coast species are also similar, but more easily separated by their association with hardwoods, and/or their consistently mosaic-like, cracked caps, and/or their strong blue staining; see Xerocomellus diffractus for a run-down"

Missed "young" stage on this one. Wrinkles not very prominent and not sufficient for confident ID, but enough to lean towards likely atropurpureus.

In wood chip landscaping. Mild mushroom odor and flavor. Cap extremely viscid!
