Striations aren’t always visible when the cap hasn’t expanded (it’s dependent on the species). I thought I saw the short beginnings of striations on the left hand side of the cap in the middle picture.

Very best,

sp-501 seems to fit this specimen pretty well, right down to the bruising on the stem. The only question I have is that there are no striations apparent on the cap. Is this just because it hasn’t opened fully at this stage of growth?

I suggest that you take a look at….

which provides information about a gemmatoid taxon that is widely distributed in the eastern U.S. It is one of the candidates for the old, poorly understood name Amanita russuloides.

If you should happen to collect and dry mature (spore bearing) material of this from Tennessee, we would be very interested in having such material (documented by illustration, etc. on MO) for our study.

Very best,
