I noticed many m,ushrooms are not poisonous bu not edible either.
I dont recommend it but I know an, Italian fella in his 80's whjo always said, if teh bugs and deer eat it, so can people. I always investigate wild mushrooms but did discover the "Bay Bolete" this way. Of course maggots like em too.
Steve, I kow there are mushrooms on the west coast but I am not sure of Colorodo. Usually there are Foraging forums that give local updates. I know out west places of recent forest fires are hot spots for Morels. Good Luck!
