Thanks for directing me back to this observation. I checked the spores of the single specimen that ended up with me from this collection; and it appears that this observation and 108463 both appear to be Amanita sagittaria.

Sometime later today, I hope to have the WAO page for this species updated with the northernmost known collecting site for this species—-namely the Franklin Parter Preserve in Chatsworth, NJ.

Very best,


Again thanks for posting the images.
