elongata?

My first guess would be Amanita elongata Peck. This has narrower spores than do the named varieties of A. flavoconia.

I don’t see any reddish staining in your pix at all which suggest that A. flavorubens would not be a good guess.

Since you have dried material you could check for amyloid reaction of spores and spore size and shape. That might be enough to nail the identity. The spores measurements for Amanita elongata and Amanita flavorubens are very close. Shape information (length/width ratio or Q) is provided on the Amanita Studies pages checklists for Great Smoky Mountains Nat. Pk. (USA), New Jersey Pine Barrens (USA), and Gros Morne Nat. Pk. (Prov. Newfoundland & Labrador, Canada).
