Most of the outer cape (Eastham, north) is Pinus rigida; oak and beech in some areas and a couple of Atlantic White Cedar swamps.

There was a lot of it growing at the edges of the natural cranberry bogs near Provincetown, which have no standing water but are a lot wetter then the surrounding dunes…
To me it didn’t smell like apples. (it smelled like a mushroom)

Nice find.

the delicate two-toned annulus is amazing, and the obscure volva at the base intriguing. nice to not only have a photo and a name, but a backstory. Thanks guys.

Nice find, Noah

Gary Lincoff was, I think, the first person to tell me that this species was to be found on Cape Cod. Morris was a member of the Boston Mycological Society in the early 20th Cent. The mail deliveries were so frequent then that he could mail a metal box of fresh mushrooms from Salem to Peck in Albany, NY and have the mushrooms arrive the same day or early the next (via train). Morris is reputed to have been rather shy. He reported to the BMS that this mushroom was going to be named “Amanita bicolor”; however, Peck changed his mind and named it for Morris, which resulted in Morris’ being very embarrassed that he had provided incorrect information to his club. Morris painted beautiful water colors that are to be found (extremely well-preserved) in a Museum in Salem.
