No specimen available

Fly agarics aren’t just sprouting everywhere in Zone 01. This small group was in Zone 44 and I found others in 45 and 48. The ones in Zone 44 were close to the boundary with 45, so all of them (and the Zone 01 instances) have Populus tremuloides within mycorrhizae range. I suspect from the distributions of both the fly agarics and the quaking aspen trees that the latter are the host.

These woods…

…are rife with pines, with P. strobus and P. resinosa pretty much ubiquitous in particular. But the fly agarics seem confined to a subset of the woods, and all of those areas seem to either contain or be fairly close to aspen. Of course there might be another thing limiting the distribution of the fly agarics, such as soil chemistry. I don’t know of any test to figure out which thing it is, that I could perform with my resources.

Ectomycorrhizal associations

When considering ectomycorrhizal associations, remember a trees roots can extend 1.5 times the height of the tree, or more. I see pine needles.
