These photos are of the best of two that were found in a mixed conifer forest (predominantly Bishop pine).

definitely the “pseudo-breckonii.” It has a little bulb like a phalloides, a membranous volval sac, and a yellowish cap, but no annulus. This critter has been stumping us for years, but will eventually get its own name.

I originally called it gemmata var exannulata, as per Rod Tulloss.

I was wondering when these would pop locally. A little more rain would surely help to pop more.

Thank you Dimitar,

I think you have nailed it. I was getting hung up on the consistency of universal veil material, which is thinner, smoother, and tougher than the granular or crystalline nature of gemmata. Nice photos by Ron.

This is one of our standard Amanitas in the gemmata group

This is the one with the more cottony veil — I/we called it A. pseudo-breckonii. See on MushroomHobby, there is an excellent photo by Ron Pastorino.

are thin and smooth, might be a better description.

Thank you Rod,

though I don’t know about Augusta. The veil material has no hint of yellow beneath the cap. Confusing features. The uv remnants on the cap were thin—no wart-like structures.

Mike, yes, I saw this posting.

The long, gradual expansion of the bulb on this specimen doesn’t look like a bulb on the stem of a species of section Phalloideae. My first thought was that it might be a species in sect. Validae. I’ve collected augusta myself at Salt Point some years back. When it’s dry (or sooner), a drop of Melzer’s reagent will probably be helpful.

Very best,
