When: 2009-07-13
Collection location: Strouds Run State Park, Athens, Ohio, USA [Click for map]
Notes:
These little amanitas were growing under mixed hardwoods in an area dominated by oak. They are about four inches tall. They seem a little too colorful to be A. bisporigera.

Just weathered A. bisporigera.
I’m not in Athens at the monment, but I will try to collect a specimen when I return in a few days. The color in these photos might be a bit exagerated due to masking effects of the dark background, but the mushrooms are clearly not white.
I can’t think of another possibility at the moment. Since this is an introduced and (at least sometimes) invasive species, it ought to be confirmed as to its identity. Dried material may be useful to Dr. Anne Pringle at Harvard who is continuing a study of the species. She has a large genetic database based on collections from all over the world. I don’t know if she has a sample from Ohio.
Very best,
Rod
the cap’s a bit conic for phalloides, too, but the color is spot on, and it’s certainly in section phalloides.
does bisporigera even come in green? I have never heard that, but don’t collect it that much when traveling east, or see it at all out here in the west.
don’t know if phalloides has been recorded for OH yet, but it IS an invasive MR species, and it could just be a matter of time…if it IS phalloides, documentation is important.
but what is up with the yellow-green color for bisporigera?
I’ve only seen ’em in white, except for a pinkish capped one that I found along the Appalachian trail a few years back…
The flimsy annulus also seems off for A. citrina. This along with slender stipe and conic cap point away from A. citrina.

makes sense, esp. if the mushroom colors were exaggerated in Dan’s photo.
But if you do return, Dan, and find younger material with that green coloration I would be very interested in seeing it. Our western “Destroying Angel”, A. ocreata never turns green, altho it can pick up other colors on the cap like brown or tan as it ages.
