Notes: This collection of Amanitas (several specimens, young as well as mature) immediately suggest section Vaginatae, as they have no ring, but do have a very tall, leathery saccate volva. The surprise is that they bruise reddish where handled or the tissue is cut (or nibbled by insects or slugs, as many were). Saccate volva does not become a gray color as with A. sinicoflava. I guess further confirmation of section Amidella here would be with Melzer’s on spores which I did not do. Fresh specimens are very light cream to buff color; shades of pink or peach color on cap and stem; a very thin “skullcap” of universal veil can be seen on immature specimens; others have fragmented scales of universal veil (caps definitely not “clean” as in A. fulva). Caps marginate and very young specimens show very slight appendiculate margins. And here’s the clincher: when dried slowly in open air (not in a forced air dryer), the gills darken to a brown. Likewise the stems and especially the caps darkened within a few hours of being collected.

experience and bacterial cloning show that whtetstoneae is one of the species in which there are multiple different versions of the nrITS in the genome. Dr. Hughes was able to show the variability through bacterial cloning before she retired.
I will never promise a date for a publication. However, it is fair to say that a description for whetstoneae is actively being pursued.
now, how ’bout making that “proposed” name official?
You have so many of these out there Rod, I hope that you can find the time to make them “real,” especially those like whetstoneae and banningiana that are readily recognizable and whose names are already in common use.
It was great that pruitti made that first cut. Here’s to more of the same.
We got a very nice ’proposed fungal barcode" sequence from this material. It supports the id based on looking at the picture.
…amyloidiosity (?)…amyloidiness (?)
we’ve all (who have collected this sp.) gone through that thought process. ;)
I never checked its spores for amyloidity either, a quick way to get you right outta vaginatae! ;)
Neat find, an amidella with some very curious features. It would be super interesting to run the DNA on this one, and see where it falls out. Any eastern lab-o-phile takers?
Still a provisional name though, (sigh). Please Rod, publish some of these recognizable species (banningiana also comes to mind)! We use these names as easily as though they were already published…
