Yes it does appear to be a two-layered annulus, and I think there may be a mild cedary smell, though it’s not especially distinct. Thanks for lending your expertise!

Yellow-bruising might be related to early stages of the…

yellowing syndrome…which is illustrated on WAO using a different species, but is not uncommon in section Lepidella in North America and elsewhere.

That looks like a two-layered partial veil in the cross-section, AJ.

If I’m interpreting the picture correctly, that is the phenomenon that I have tried to describe a couple of times on MO. This double annulus occurs in some species of Amanita subsection Solitariae (within section Lepidella). The European A. soliataria pulls this trick; and the North Americans that can do it are A. cokeri and A. subcokeri, so far as is known.

Both may lack an odor at first; however, subcokeri soon gets an odor that (to my nose) smells like a mixture of cedar wood and burnt sugar…to me a pleasant and distinctive odor. Amanita cokeri persists in an odorless condition until it starts to get old and then has the “old ham” or “decaying protein” smell.
