Collection location: Sweet Valley, Pennsylvania, USA [Click for map]

Who: Phil Yeager (gunchky)

No specimen available

Mixed woods. Ash, Oak, White Pine, Hickory. Top of mushroom has a large remnant of the UV, and the gills are still covered by the partial veil. There was some moisture in the soil but the stipe was peeling. One portion of the UV seems longer than the rest. Don’t remember any odor, and I didn’t taste it or apply any chemicals to it.

PV appears to be white on this specimen. So my guess is that bisporigera best applies.

Looking at the Amanita website, I see there are a few other characters that potentially point toward magnivelaris… spores not globose and nil-to-weak yellow reaction to KOH.

Amanita magnivelaris has strong distinguishing characters associated with the partial veil. In this species the partial veil is distinctly off-white, more cream-colored, and has a very different texture from all other North American white destroying angels—-namely,the partial veil has a distinctly felted appearance and is noticeably thicker than the typical partial veil in the group.

Very best,
