Help with I.D. of these (fungus, trees, etc)?

Alnus incana maybe rather than Alnus rubra - my mistake

[daltontrees]

I thoguht about the Alnuses too, the leaf shape is about right for incana or rubra but the leaves are too glossy and stiff. And these pictures show leaves in whorls off a spur, like you would expect from Rosaceae or maybe some hybrid poplars but for sure not Alnus.

 

I keep coming back to Pyrus
