Notice the yellow rings at base of stipe. Also the yellow veil remnants on the cap.
These could be var. guessowii

Notice there are no “concentric rings” on these two specimens at the top of the bulb of the stipe. Also the steady display of color throughout the cap.

This specimen also has no visible rings at the base of the stipe. And consistent coloring also. ? var. persicina?

I found these today (July 12, 2013)and thought they looked amazing. So I added them to the image collection. In my opinion, these are a very good example.

The material that I have seen and collected in NC and TN had uneven distribution…

of color when it was fresh. The material I collected in open pine forest in Mississippi (a lot of sun could reach the forest floor) became evenly pigmented (just like your evenly pigmented material) even in the button stage. Molecular study (Geml et al. 2008) produced the information that all the collections were from a single species for which the only current name is “Amanita muscaria var. persicina.”

The Geml et al. paper is:

Geml, J., R. E. Tulloss, G. A. Laursen, N. A. Sazanova and D. L. Taylor. 2008. Evidence for strong inter- and intracontinental phylogeographic structure in Amanita muscaria, a wind-dispersed ectomycorrhizal basidiomycete. Molec. Phylog. Evol. 48: 694-701.

Dr. Geml is now located at the National Herbarium of the Netherlands, Leiden.

Very best,

Maybe two different Amanitas

It appears as though I may have actually picked two different Amanitas. Judging from the images, one variety has concentric rings around the base of the stipe (var. Guessowii?) and the other doesn’t. Also, one has consistent coloring throughout the cap (var. Persicina?) and the other doesn’t.

Thanks!

I went ahead and picked these guys just in case they are var. Persicina. They were plentiful.
Are there any observations you noticed that made you for sure that these are indeed Persicina?

That’s a very nice collection.

I think that it probably is var. persicina.
