Take a look at the side view image…

Especially, view the side view image in Photoshop. Modify with Auto Contrast and then with Auto Levels. The red is still over saturated (common in digital cameras), but you can see that the volval material is yellow at the stem base and there are wine-red (too red here) bruises around the edges of a slug or insect lunch area as well as around and between the warts of volval material on the bulb. This amount of surface staining would be VERY VERY unusual for A. flavoconia. The stipe surface also is more fibrillose than is usual for A. flavoconia. Usually, the immature cap of A. flavoconia is more rounded-conic or bell-shaped. I would say this is more probably A. flavorubens, for which I cast my vote.

Very best,
