Colorado Mushrooms

A variety of mushrooms can be found in the Rocky Mountains. “Mushrooms of the Rocky Mountain Region” by Vera Evenson outlines over 220 species of mushrooms that can be found in Colorado, New Mexico, Utah, and Wyoming. The late summer months of 2021 proved to bring forth a bountiful amount of mushrooms growing throughout Gilpin County, Colo.

Several distinctive toadstools featuring bright red caps scattered with pale warts could be found growing among the woodlands in the first week of August. The fly agaric (Amanita muscaria) is a red-capped, white-spotted mushroom that can be found July through September. This mushroom has hallucinogenic properties and is highly toxic when consumed.

The bolete (Boletus edulis) is a large mushroom with a brown cap and a bulky stalk that can be found July through September growing at high elevations underneath conifer and spruce trees. Bolete mushrooms make for a good forage find because they are considered to be edible. This mushroom was also found plentifully growing throughout August.

Another mushroom that was found growing in the forests of Gilpin County, Colo. was the sickener (Russula emetica). This is a medium-sized, brightly colored mushroom with a red cap and a white stalk that can be found in the summer and fall months growing among conifer trees and mosses. As suggested by its name, the sickener is a poisonous mushroom.
