Cortinarius largentii is named after Humboldt State University mycologist David Largent. It is an attractive species recognized by a smooth, glutinous, yellow and tawny cap, lilac young gills, a pallid stipe with a distinctly marginate basal bulb, and a red KOH reaction on the cap surface. It belongs to the Cortinarius calochrous species complex, which includes several difficult-to-separate species characterized by this suite of features.
