If the fibrils took on the color…

If the fibrils changed, they changed. I would stick with the determination. A change in the context color might be unusual…

It was the fibrils first, then the stipe so I dont know what that means.

It’s the fibrils that are noted to turn color, not the stipe context….

I’m not sure what meaning can be taken from the stipe context yellowing. It is the surface fibrils that are reported to change to a “pinkish gold” (and I can confirm that I have seen this change on material from Alabama to New England).

Very best,

Rod

I scraped the stipe near the apex with my fingernail, it stained a golden yellow color as you said it would Rod.

Thanks for the info on this species.

I am trying to write a list of all the different species of Amanita that occur in northern GA so your tips help a lot.

I have not noticed any staining on the stipe, I just scraped it to see what that would do.

Yes it is fresh.

Thanks for the compliment!

Nice shots of warts!

Look for a spot of stipe surface that is relatively undamaged and touch the raised fibrils. See if any turn gold, orange or pinkish gold. It could be Amanita canescens. If it opens wider and the area of white on the margin expands to account for a larger area of the completely expanded cap, it would look quite a bit like collections of A. canescens made recently in New Jersey.

Very best,

Rod
