A. junquillea var. exannulata

is invalid, and from Denmark. No way this is the same species.

gemmata var. exannulata is ..

a synonym for A. junquillea var. exannulata, published in 1935.
so yes, it is published. but no, it is not the exact sp. that we have here, probably.

again, the work has NOT been done, but that is a name that we have used for our western species that lacks a partial veil and has a UV that climbs up over the bulb (no neat rim), and a yellowish cap. pseudobreckonii is a “name come lately.” use it if you want. I have used both, but I prefer exannulata.

isn’t published, either. I prefer the exannulata name.

once something gets officially published for this species, why, I’ll use that name. we’re not there yet.

amanita alone is not good enough. we know this species, it just doesn’t have a good published name, yet.

It appears the type for your selected varietal name is also unpublished and from Denmark.

he was the one to first propose this name to me, many many moons ago.

Perhaps you can show me where Amanita gemmata var. exannulata was published? Thank you.

pseudobreckonii is not a real published name.

the term “pseudobreckonii” was coined because this clearly wasn’t breckonii.

the original name for this sp. was gemmata var. exannulata.

it was Darvin who first started convincing me to call these breckonii, which I only did so reluctantly.

we all agree these are not the true breckonii, which no one has really ever seen that is still alive.
dessicata exists, but that doesn’t tell us what the fresh fb looked like.

when this western species gets fully described, DNA analyzed and published, then we can run around and change all of the names to a new real name. until then, it’s just what you prefer to call it.

Ok thanks

I didn’t realize you had two different species here, what are the microscopic differences between this species and A. breckonii.

we really haven’t resolved…

just what these exannulate “gemmata” types with the flaring volvas really are.
at this point in time I feel most comfortable calling them exannulata, but this is probably just another western amanita in need of a new name.

Dimi did show that these are most likely NOT breckonii, by comparing some of my collections with the breckonii type specimens at SFSU herbariuum.
