is probably an artifact of the lighting. I think the newer observations’ photos were taken later in the day, for one thing. Also, not with the same camera.

The other two observations you cited showed yellow stipes. I imagine that that could be a false color picked up in the photography. The species presented here in 10766 has a white stipe. Considering you locality and the plenitude of the American interpretation of “fulva” and the possibility that the photos with the two more recent observation might have displayed stipes that are falsely yellow, then I think it is a possibility that they could all represent the same taxon. That taxon could be the same as is commonly called “fulva” in the northeastern U.S. I saw a different species with with somewhat similar cap coloration on the Island of Newfoundland during the first several years of Newfoundland forays. You might want to take a look at the illustrated checklist for Newfoundland & Labrador which can be reached from the keys & checklists page of the Amanita Studies site.

Very best,

http://www.mushroomobserver.org/23770 and http://www.mushroomobserver.org/23756 for similar observations from the same area about one year later, with superior photographs. Probably all three observations are of the same species.

I wouldn’t mind seeing yours, Noah’s, and/or amanitarita’s opinions on these amanitas.

the American “fulva”?

If the volval sack develops rusty staining, one reasonable guess would be that this is “Amanita fulva in the sense of eastern N. American authors.”
