With enthusiasm for mycology at an all-time high, a consortium of Colorado mycologists, societies and associations (Crested Butte Botanic Gardens, Denver Botanic Gardens, Colorado Mycological Society, Pikes Peak Mycological Society and the Western Colorado Mycological Association) have spearheaded an effort to enact a state mushroom. Other states across the country already recognize fungi in their state emblems, and we have come together to launch the campaign to make Agaricus julius Colorado’s state mushroom.

Why Agaricus julius?

It associates with another Colorado state emblem, spruce trees, and grows in our high mountain environments.

It was first described in Colorado and grows throughout Colorado’s mountains. It was previously thought to be the “Prince” mushroom. However it was found to be a distinct species, which is now commonly referred to as the “Emperor.”

It is a prized edible mushroom, sought after by mushroom hunters and chefs, and is easily identified by people of all ages.

No other state has a species of Agaricus as its state symbol, which would make it original to Colorado.

The species is taxonomically “stable.” This means the species will not be re-categorized as a different species in the near future.

Colorado Rep. Jacque Phillips (D-Thornton) sponsored the bill, which was approved by the House of Representatives, and it is co-sponsored by state Sen. Cleave Simpson (R-Alamosa), who represents many of us on the Western Slope. It is now awaiting approval by the Senate. Please sign our petition at change.org/costatemushroom to show our state representatives that this issue matters to Coloradans.
