Amanita species 06: The Spotted Salamander
by Michael Kuo
See? This is another reason "common names" are a bad idea. I've got no inspiration--none whatsoever--and I need to come up with some kind of a name for this officially undescribed species. So I Google "brown with yellow spots," and discover that Ambystoma maculatum, the spotted salamander, looks a little bit (just a little) like the mushroom in question. Some day, a taxonomist somewhere will give this little guy an official Latin name, and hopefully it won't be "Amanita ambystomoides." For now, though, you're stuck with my salamander comparison.
Although I've only collected it once, this beautiful little mushroom is easily recognized and quite distinct. The cap is brown, and features yellow warts. The stem has a fragile ring and, at its base, loose fragments of yellow universal veil, reminiscent of Amanita flavoconia. The species is vaguely similar to the western species Amanita augusta, but is smaller and more fragile.
My apologies for the truly lousy mushroom photos, and my thanks to John Denk for the great shot of the (real) spotted salamander.
