This grisette probably deserves a cryptonomen temporarium to be assigned by Rod. :-)

I first ran across 287777, and it immediately caught my eye, looked familiar. Pretty close resemblance to the one in this obs (216467). As seen in my initial proposals, I thought this unusual little grisette may be one of the diminutive Caesars sans annulus.

Dave and Rod, I think this could well be the same species as obs 287777 collected by me last year in NJ.
The diminutive size, the grayish-brown cap fading toward the tuberculate margin, a very dark umbo sitting inside a broad umbilicate area and very long striations spanning ~50% of the radius, the widely-spaced gills, and the long saccate volva are the readily recognizable field characters that separate this tiny critter from other species in sect. Vaginatae.

Herbarium Rooseveltensis Amanitarum (R. E. Tulloss) has received specimen.

We have received the dried specimen and it is being accessioned for Rod’s herbarium. Thank you very much.

Thanks, Rod.

I also wondered about the umbo as possibly a questionable Caesareae trait.

The volval sac is not usually so large as this in virginiana.

Also, virginiana is often more brown than gray and is often pallid over the cap’s marginal striations.

Very best,

Rod
