haven’t yet acquired a microscope and still learning subtler differences

Good spot on the pin oak.

It is unlikely to be vaginata (from what we know so far) in North America.

I see a pin oak leaf (I think) in the background. In New Jersey we have a gray species with pin oak and other oaks of the red oak group. In fact it grows on my lawn. The eastern species has ellipsoid spores. I wonder what the spores are like in your material.

Very best,
