Hello, Judi.

The very dark young caps are something that I’m not sure I’ve seen before. In the more mature specimens, the bulb is not the right shape for brunnescens. The fine radial lines of pigment on the cap and fairly large skirt make me think of Amanita submaculata:

To me, A. submaculata develops a distinctly fruity smell…something like apples.

Recent research show that submaculata ranges from Quebec to Texas. I’d guess you are in its range.

There’s a bunch of data on the species on the above web page.

As if there weren’t enough pictures of A. brunnescens and its curious bulb, there are more here:

Very best,
