The bulb made me suspect this was not A. citrina.

Amanita aestivalis was described as like A. brunnescens (see cleft bulb in bottom image), but slower to bruise/stain and having a cap that was white, not virgate, and sometimes having some yellow over the disc. The umbo is not present in A. citrina or in either of the taxa that are called A. citrina in North America.

Singer said that A. aestivalis was rather common. In the NE U.S., I’d say it appears occasionally. It may be more frequent to the south of NJ and to the west of PA.

Very best,
