If you sequence the ITS, you could compare it with GenBank KJ609511 for A. sp. ‘RWK 2125’.

plus it’s totally the wrong season for them. I expect we’ll be sending it for DNA sequencing.

For example, the margin and undersurface of the ring would be much more typical of a species in the toxic section Xanthodermatei. There is an undescribed species on the west Coast (CA) that is reasonably similar.
