looked at images of both Amanita flavoconia & Amanita frostiana, more in common w/Amanita flavoconia

I’m just an amateur observer, but from studying images of both zoomed in, I see more in common with Amanita flavoconia. The stem of the Amanita frostiana images all seem to be a bright yellow, where the stems of the Amanita flavoconia are more pale yellow or white as in my image. As in image Amanita flavoconia G. F. Atk. (24892). Thanks for the help.

fair enough…my eastern amanita collecting experience is limited.

I don’t think this is A. frostiana…

The cap in A. frostiana is not conical in my experience. The volva can be, or become, white in A. flavoconia. The margin can often be striate in small fruiting bodies of A. flavoconia (marginal striation is directly related to thinness of cap context). I think A. flavoconia is still the best bet.

Of course, we can never really know….

I took the photo as I was exploring the park. Since I photograph nature and not just mushrooms, I didn’t conduct a thorough photo essay of the subjct. Sorry. Thanks for the help though.

Possible Amanita

With the patches still remaining on the cap and the prominent annulus on the stipe, this could be an Amanita. Would need to see what was at the base of the stipe (stem).

Need to see more

Need the underside, are there gills on not? Of what color? Then what is the shape of the base?
