Amanita section vaginatae
(The Grisette, Amanita vaginata)
Grows in the mountains and are mycorrhizal with aspen as well as conifers.
The standard Amanita vaginata has a greyish brown cap with ridges on the edges. Grows out of a volva, has a point on the center of the cap, ridges on cap edge, without a veil and no ring. Other similar Amanita's are also called grisettes. This mushroom has a few poisonous look-alikes. There are several variations of the vaginata section of Amanita in Colorado. They are still being studied as they are a complex of species hence the variation. Although a few experts may eat some of these mushrooms it is not recommended due to similar deadly poisonous Amanita's that they could be confused with. Although those are rare in Colorado is it really worth it?
Amanita stannea (not an official species name also pictured here) is a similar mushroom however it has spots on the cap and a rusty orange coloration on the veil remnants.
Amanita barrowsii (not official species, pictured last) is another in sect. vaginatae. A. barrowsii contains an orange cap.
Amanita populiphila is another similar mushroom with a lighter orange / tan cap that grows with the poplars Aspen and Cottonwood.
