Notes: Significant patches of this grey-green, leaflike (foliose?) lichen now grow on the ground in Zone 14, a nearly pure stand of quaking aspen with scattered Pinus banksiana and Pinus virginiana about it.
Underside is whitish with rootlike projections (rhizines?).
The only genus name that comes to mind is Parmelia, just from seeing it on leafy/lobed looking lichen obs here. I wouldn’t put any money on it.
