Cortinarius fuligineofolius can be distinguished by a smooth, viscid, reddish brown to ochraceous cap with darker watery splotches, olive-gray young gills, a bluish gray to violet-gray stipe apex, and a white bulbous base with yellowish green veil remnants. The tri-colored context—dingy brown in the cap, violet in the stipe apex, and white at the base—that turns red in Melzer’s reagent is also diagnostic. Cortinarius fuligineofolius is a commonly encountered member of the Cortinarius scaurus complex in coastal mixed hardwood-conifer forests in northern California.
