If this taxon can be re-located, I would be glad to take a look at the material.

The cap is a bit yellow for murrilliana and lacks the brownish center; however, a very whitish collection from Quebec (handed to me at a foray by Yves Lamoureux) turned out to be murrilliana. (Years later, Santiago Sanchez extracted DNA from the Quebec material and it matches all the other the other murrilliana material from which he obtained sequences.)

Very best,

I can see striations on the cap, but it’s difficult to say how long they are. In combination with the membraneous volva and annulus, these traits suggest section Caesarea. But the cap color does not bring to my mind any species from this section. Checked the Amanita Studies website and the only thing I can find that’s close is A. murrilliana. Seemingly a puzzler…?
