This seems to be the same entity I saw in Norway…

This seems to be the same thing that I saw in Norway as discussed earlier on this site (e.g., in a comment on MO 16039…that comment refers to a possibly useful key to rubescent amanitas). IYour pictured collection and my Norwegian collection seem very like A. novinupta in general appearance.

Coker’s taxon, A. rubescens var. alba is quite different. For example, the blushing in young material of the latter is slow and superficial (NOT appearing to be within the context below a transluscent surface layer as in A. novinupta). Moreover, A. rubescens var. alba has distinctively different spores and shares with A. flavorubens and “A. amerirubescens” the characteristic that the universal veil is often distinctly yellow at first.

Sometimes the yellow universal veil of the American taxa remains on the UNDERSIDE of the partial veil in the three major eastern, N. Amer., rubescent taxa. This is quite different from the sulfur yellow annulus (completely pigmented) characteristic of the European material sometimes called A. rubescens f. annulosulfurea.

Very best,
