• Comments

  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.

  If you choose to accept the recent division of Cortinarius into 10 genera, the correct name for this taxon is Thaxterogaster fuligineofolius (see Liimatainen et al.)
