It’s a very common in the southwest, and maddeningly variable. Knudsen had some interesting comments about it in Mycotaxon 2005, 93: 289-295. The key thing is: “The major characteristics… are the formation of well-developed squamules, a stipe, … [and spore stuff].” (He neglected to mention that it’s yellow. :)

Without chemistry and microscopy I don’t think you can do any better than play the odds.
