Observation 10140: Amanita solaniolens H.L. Stewart & Grund
When: 2008-08-10
Herbarium specimen reported

Notes: Found under mostly maple and oak, mostly oak, but also in the mixed forest of other things. Has a bulbous base, not really a volva. Smallish, the larger cap is about 3cm in diameter.

9/6/2008 – Looking at the spores here.

The micro-shot is of spores from the veil tissue at 1000x in Meltzer’s. Here the spores are globose and amyloid. The rough size of the spores are about 8 um in diameter.

Looking at the discriptions for A. solaniolens and A. brunnescens, unfortunately it looks like these both agree, so no news there.

So, these might be either really as far as I can tell. I’ll add A. brunnescens as a possible name also.

I was gonna conjecture as to this species, but was mostly unsure…didn’t quite fit any concept that I knew. Almost named it brunnescens var. pallida, but the bulb and cap were off…nice to see in your solaniolens treatment that brunnescens is the mushroom that is the most likely mistaken identity!
Glad that I am in the ballpark, at least. With your help, we’ll start hitting ’em out of the park!

I also noticed that you are looking for a good photo of this sp….check out David Fischer’s work, here:

This is not the only amanita that smells like freshly dug potatoes, but it is a small one with a yellowish annulus and virgate pigmentation similar to that seen in the caps in Douglas’ photos. In fact, Douglas’ photos may show a somewhat bleached or rainwashed specimen. There is no picture on the species page for A. solaniolens on the Amanita Studies website, but the color description is rather clear. A dark specimen of what I take to be solaniolens is depicted
here.

Very best,

Rod
