Observation 207507: Amanita canescens Dav. T. Jenkins
When: 2015-06-20

Notes: Hardwoods, mainly oak.

Prominent reddish-brown stain in stipe base.

A nice opportunity to use the Meltzer’s that I scored the same day this was found.

Browsing the Amanita Studies website, I see there are a few species from Validae that have the large pyramidal warts on the cap.

Seems like an interesting species. Material preserved and in good shape.

The only thing that doesn’t fit canescens…

is the prominent brown stain seen in the stipe base. This is my reason for retaining the “could be” on the Validae proposal. But I think the browning of the material in the stipe may be due to soil pigment seeping into the mushroom. There had been a lot of rainfall during the several days prior to finding this. There is also some yellow on the annulus.

Spores in side view mostly with 1.8 < q < 2, and a few with q > 2.

You might also consider A. canescens.
