I’m confident that both these fungi are Amanitas, even though the volva is not visible in the first photo. Both are pale pinkish-gray, with the second picture being a separate specimen also showing the saclike volva much better. Second picture also has slightly umbonate cap, and shows edge striations on cap better. Stipe with white scruffy scales on a very light grayish-white stipe. Once again in Aurora keys out to A. velosa, which I don’t believe I have in my area.

We have several recent postings of various taxa of “grisettes” (species of sect. Vaginatae). Many of these taxa have not been described. A good color photograph is not obtained without effort. Given that effort, collecting and drying the subject of the photograph is a small additional act. That additional act can make it possible for these pictures to get names put on them. I feel terribly frustrated with “cf. vaginata”, “the vaginata-group,” etc.
Given the large area of the world from which MO draws contributions, MO should be given the chance to maximize its potential impact on taxonomy. This would be most likely to happen if (as an example) all “grisette” pictures were backed with well-preserved herbarium specimens.
The key athttp://pluto.njcc.com/~ret/amanita/key.dir/pnwcakey.pdf
Covers a larger number of taxa than Arora. Try looking at the part relevant to sect. Vaginatae. The key is certainly provisional and does require microscopy, but you can use it to learn more options than you now know. The key utilizes (to the degree possible) unpublished data from decades of collecting by people such as A. H. Smith and a number of West Coast collectors (including MO participants).
Just found another observation under A. vaginata which looks amazingly similar.
This is a big group that needs work; no key exists that will name them all.
Actually, the first photo is the one that shows the features better.
