the browning rather than reddening of the cap warts is also a good indication that this was not novinupta.

Christian called it.

But more than just the size of the warts tell the ID tale.

What about A. novinupta?

The scales on this one are rather flat and small. I have had this problem before, and have found that A. novinupta is common under oak in fall as well as spring, and can suggest A. magniverrucata before it shows reddening.
