Same exact spot as obs 277335. Several mature Norway spruce trees surrounded these mushrooms, the closest one about 6 feet away. Across a grassy road, about 50 feet away there is a hemlock, approximately 30 feet in height. It is conceivable that the mushrooms are associated with the hemlock. But it looks like the association is with Norway spruce.

I should have consulted C du Q seeing as Yves Lamoureux is the author of A praecox. Amanita stranella is another name that may apply to a similar species. I suspect there’s no difference between praecox and stranella. In my experience, praecox seems to occur with native hemlock, as is asserted on the Amanita Studies website. So the possibility that the species also associates with planted Norway spruce is worth investigating.
In section Amanita, the yellow-capped ones with marginal/limbate/indistinct basal volva seem like an interesting group.
from Lamoureux’s praecox webpage:
“On coniferous ground, with spruce, pine, hemlock and fir.”
trying to guess just which tree is associated with these MR species, when there is more than one tree species nearby!
A classic example was when I found an Amanita phalloides under a Deodar Cedar (of all things) at our local, tree studded, spectacular, Olmsted designed Mountain View Cemetery in Oakland. There was indeed a live oak within view, but over 70 feet away (I paced it off!). I actually dug down below that amanita to attempt to get some of the MR nodes (rather socially awkward to be wielding a trowel in a cemetery), and mailed it off to Ben Wolfe, at that time in the PhD program at Harvard. But he was very close to graduating, and I think it just got lost in the shuffle.
I sure wish that Lamoureux would publish this species. Too many nom. provs in the NA amanita world!
Still good to at least have a placeholder name, and to be building a database of natural history details.
