I am only guessing, but this looks like photos I have seen of Amanita brunnescens. I have very little field experience with mushrooms. Just started this hobby a few months ago. This particular mushroom was found when it had just poked above the soil. Dug it out with my pocket knife, but it is possible I did not get the entire stalk. I know it is important to secure the whole thing. The first two photos were taken at Hawn State Park and the following ones were taken at my home. The total length was about 6".
