like, for instance, this species, I am lost in my eastern grisette world. There seems to be a perplexing diversity here.

in your eastern grisette world!
it’s bad enough here in the west!

still, with enough field time, you start to get a handle on what is out there …

is how I would describe the cap color of the A. rhacopus types. These types also have the friable graying volva. Rhacopus types and sinicoflava are both common here in NE NA. So it’s a good idea to distinguish the subtle differences in cap color.

I wouldn’t call this cap “gray brown”

it has more of a mustard yellow tone to it, very different than most gray or brown or combo grisettes.

Here is how Rod describes it on his webpage:

“Amanita sinicoflava has a Chinese yellow or “curry powder colored” or yellow-olivaceous or olive-tan cap"

the gray volva seems very distinctive, too.
in combination with this distinctive cap color, seems like a fairly easy ID.

for a grisette.

we have lots of “vaginate” amanitas aka grisettes, but I thought we didn’t have the true Amanita vaginata here in NA.

Noah. I was originally going to post this as A. vaginata var. livida after reading several books which mentioned various colored caps in this species. Didn’t read about the consistently white UV. or missed it altogether.

has a gray cap and a white unchanging UV

These two are hard to differentiate from one another.
