American Tawny Grissette – Amanita fulva

My sources say it is an American species.

Lincoff pg 536

“Range: Throughout North America”

Arora pg 287

“I have seen large fruitings in the aspen conifer forests of the Rocky Mountains in late summer”

After taking a closer look, I’m not sure if that is a striate margin as I originally saw, or if those are “radially oriented embedded ‘hairs’” like Rod saw. However, the dark spot at the center of the cap looks more tawny than gray to me.

The long strait white stem, absence of an annulus or warts on the cap, distinct vulva, radially lined margin, and free white gills all together suggests a grisette; and it looks more brown than gray to me.

Of course if it has a hairy cap it is something else.

Cannot be Amanita fulva…

Amanita fulva is a European species. The pileus is fulvous (orange-brown) sometimes with a darker brown center. It does not have the appearance of radially oriented embedded “hairs” as does the present species. The cap margin of A. fulva is markedly grooved (striate or sulcate). From the appearance of the cap the present species cannot be placed in Amanita sect. Vaginatae even if it could be placed in Amanita.
