This mushroom has a bright cinnamon to rust-colored, bell-shaped cap, sometimes with a knob, sometimes flat, 1-1/4 to 2-3/8 inches wide.
The gills attach to the stalk, colored cinnamon red at first, then rust-red. The spore print is rust-colored.
The cobweb-like partial veil that covers the immature gills leaves no ring on the stalk when the mushroom matures.
The shiny, reddish stalk is 1-1/4 to 2-3/4 inches long, 1/8 to 3/8 inches thick.
Look for it under deciduous or coniferous trees throughout eastern North America from mid-summer through fall.
It's of unknown toxicity.
