I can’t say that the lobed-ness of the volva is related to sect. Amidella; however, the thickness of the volva is.

as I recently learned, the American amidellas will often bruise pink or subtly red on both cap and stipe. What also made me curious about your photo, and lean towards an amidella ID of some kind, was the lobed volva (like flower petals).

the rarely pink destroying angels (A. bisporigera), start out pink, and stay that way.

you can see both Darv’s orange/pink ocreata

and my pink bisporigera: http://mushroomobserver.org/13053?search_seq=595911

In several species of sect. Amidella you can bring about a quick pink reaction by scraping a cap with a stick, a fingernail, or knife point (you’re trying to do more damage to the underlying tissue that you would with a surgical razor cut). The pink staining in A. bisporigera and A. ocreata is much less common and is clearly a superficial reaction on an unindented, apparently unbruised pileipellis. I hope that helps. A partially dried specimen of sect. Amidella or one growing in dry weather usually will not produce the pink response described above. I have seen the reaction especially in the smaller species of sect. Amidella in eastern N. Amer. (“pseudovolvata Tulloss nom. prov.” and Amanitopsis volvata var. elongata).

When I found this mushroom I thought it was another one of the greenish little destroying angels posted here:

This mushroom has a little bit of pink in it, which Debbie mentioned seeing in a destroying angle before. The new top photo is taken against a white paper towel to show true color.

This mushroom is now dried and available for further study.

The pink staining where the cap was scratched or rubbed…

…is a common character in some species of sect. Amidella. A small specimen in that section would often have marginal striations showing at an early stage, but these are not evident in your photographs. There are a small set of possibilities, but I’m not sure they can be segregated based on a picture.
