A number of persons have referred this mushroom to A. multisquamosa;…

however, your image clearly shows that the partial veil is not originally funnel-shaped, which would eliminate both mutlisquamosa and velatipes.

Very best,


I think this might be Amanita “__sp-AZ07”__"…

that was relatively commonly collected in the Chiricahua Mountains during the Chiricahua Mycoflora Project of the late 1980s and early 1990s. A key to amanitas of the region is available here:


Very best,


certainly something in section Amanita.

At 8,500’, you were well down along the flanks of the San Francisco Peaks. I hiked to the very top at the age of twenty, and I’ll never forget the height: 12,650, and I felt every inch!

That is way above tree line though, just rock and kachinas up there.

Meltzers is also a useful chemical for amanitas, and can help you determine sections: inamyloid (non-bluing spores) for sect. Amanita (like this one) and Vaginatae and Caesarea; amyloid (spores bluing) in sections Validae, Amidella, Lepidella, Validae and Phalloides.

KOH is sometimes useful for determining species within section Phalloides, but the reactions can be variable even within species.

We undoubtedly have a number of cryptic species within that “gemmata” umbrella here in the USA.
