I was just reading the notes I made, from a NAMA event Rod was at, and concluded that section Amanita was as far as I could get.

I agree that it is an unknown…

not a phalloides (despite that cap color), not an ocreata, and not a gemmata, since that apparently doesn’t occur out here.

lotsa work needs to be done on our western amanitas.

if you have it, or collect more, check the spores in Meltzers for amyloidity…I suspect this is in section amanita (non-amyloid spores).

How about this…

Look at the last picture (section view). Isn’t that a yellow green color in the top of the cap flesh just below what looks like a white layer of volva? What direction would this observation drive the naming exercise?

And the volva on the cap is not a smooth layer of a membranous volval patch…there’s fluffiness to it. And I can’t really be sure I see any remains of a ring/annulus…no matter how hard I look.


Nameless one!

I think this is one without a name.

This one had me wondering. Please tell me different or more?
