No bulb at the stem base…

…and a greyish bit of volval material at the base, that much I was able to see before I was assaulted.

I didn’t notice the yellow jacket deterrent…

Mushrooms with body guards! Holy mackerel and little fishes! I certainly did not mean to imply that personal injury was a necessity for the advancement of knowledge. Linnaeus sent his students out to risk their lives (and wrote letters to their families describing the value of their deaths to science…if they died in their explorations), but I HOPE taxonomic “society” has gotten over that. (??)

Very best,


Did you hear that, Hamilton?

We need a shot of the stem base, yellow jackets or no…

It’s necessary to see the stipe base…

…even in section Vaginatae. The reason is that a thin cap with long striations and dark warts could be on a species that has a bulb at the stipe base (and, hence, is in sect. Amanita rather than Vaginatae.

The dark circle around the lower stipe in A. borealisorora and the several similar taxa (all unnamed in North America) is a good character that would be valuable to determination of the “group”.

Very best,
