Cortinarius bolaris is a small to medium-sized fungus with a bell-shaped cap that ranges from 1-4 cm in diameter, typically reddish-brown to orange-brown in color. The gills are adnate to slightly decurrent and pale yellow to golden brown. The stem is slender, 2-6 cm long, and colored similarly to the cap.
