When: 2015-07-16

Collection location: Forest near Elgin St., Pembroke, Ontario, Canada [Click for map]

45.8042° -77.1356° 200m

Who: Paul Derbyshire (Twizzler)

No specimen available

A yellow fist-sized Amanita, isolated, with orange toward the center of the cap. Warts yellow. Base of stipe widens into a bulb and bears concentric rings of warts. Section Amanita seems likely. Could be a fly agaric relative. Different from the big fly agarics that grow on the periphery of a different part of the woods in mid-September though.

In Zone 48 under Pinus/Acer/Abies/Betula.

All of the photos look like they were taken in very dense fog.

Camera is fine. The in-focus parts of the images (e.g. cap warts in the first one) look pixel-sharp over here. Must be your monitor.

As for “what else could it be”, well, it’s obviously in the A. muscaria group, but I think there may be several North American species. I was just wondering if those had been sorted out yet to anyone’s satisfaction.

Your pix look kind of foggy, lacking sharpness in this obs and others. Did you get condensation in your lens?

What else can it be, Paul?

Looks like the typical “yellow amerimuscaria”. According to RET’s website, the warts are supposed to be “pale yellow to pale sordid yellow fading to off-white to cream to sordid cream on exposure, detersile”. See http://www.amanitaceae.org/.... There are enough pix in there showing yellow UV warts on cap.

This had yellow warts, rather than white, and quite a wide basal bulb. The ones I see in September in a different habitat have white warts, are larger, and have a narrower bulb. It seems unlikely that both are the same species…has anyone really sorted out the North American Amanita muscaria group taxa yet?
