Lucky puppy!

Dogs seem unusually attracted to this aroma. I find it most appealing when there is a combination of coconut and chocolate, similar to a Mounds bar, pineapple and grapefruit Lifesaver.

Several years ago had a dog owner bring a sample while I was working at The Oregonian. Dog had just had his stomach pumped, after the owner had caught him scarffing down several in his backyard near Oregon City. Because the dog had a rather expensive pedigree, the owner soon realized she would be returning him to the exact same environment shortly, and he was likely to do the same thing again. So wanted to know what the fungus was and whether it was safe. I told her she was lucky to have such a talented dog, and to make him share what he found with her.

Lighting?

That may be an artifact of the lighting, since the other half doesn’t show it. The smell was unmistakable, and ID was confirmed by Brian Luther.

Definately Leucangium. Spores close to carthusianum.

I’m only concerned about the color. L. carthusianum should not ever stain blue when sliced. Your photo shows intense blue on the left-hand specimen, first photo. The right-hand specimen is typical (but small) for L. carthusianum.

Can you expand on the color?
