Paxillus cuprinus, commonly known as the coppery pax, is a species of mushroom in the family Paxillaceae. It is found in the Pacific Northwest.[1]
Description
The cap of Paxillus cuprinus is coppery in color.[2] It starts out convex, before becoming flat. It is between 3 and 10 centimeters in diameter. The center of the cap has a dip, and the margin is inrolled. The stipe is about 3-7 centimeters long and 1.5-2.5 centimeters wide. The gills can be adnate or decurrent, and the spore print is brownish.[1] Paxillus involutus is similar.[3] However, it is rare in the Pacific Northwest, and smaller in size.[1]
