To quote RET on A. subcokeri: “More often than any other Amanita species RET has observed in the New Jersey Pine Barrens, this species is particularly likely to be found with a blue-green Penicilium species growing on the pileus warts or in cavities which may occasionally be found in the stipe context”.

Thank you both for the comments.

double annulus with fibers connecting the underside to the stipe. Also, it has a universal veil that is gray at first (on cap and stem and bulb) and becomes red brown with the passage of time. On the bulb it often does not cause the formation of recurved scales (which do often occur in cokeri and subcoker). As David said, the rows of small colored warts are rather close together and descend beyond the broadest part of the bulb (if the don’t go all the way to the bottom of it).

The true cokeri has no odor until it begins to decay. I’ve always thought that the odor of subcokeri (which can be concentrated by wrapping a fresh specimen in waxed paper for a few hours) was a mix of burnt sugar and cedar wood, but others say it is close to bacon or watermelon.

Very best,

Rod

I become confused about separating cokeri from subcokeri, except that subcokeri has spores that have larger l/w quotient than cokeri. Also it is my understanding that the range of cokeri peters out just north of the PA border. So maybe subcokeri is more likely for the one in this observation.

In my experience with what I have believed to be subcokeri, the odor is slight, pleasant, but difficult to describe.

Also, I tend to confuse these types with atkinsoniana. But atkinsoniana has (usually) smaller scales that cover most of the entire vertical length of the basal bulb.
