are given in the photo captions. I should have also added that although the two specimen locations were connected to the same driveway, the driveway length is 1600+ feet, and the specimens were 100s of feet apart.

The reported spore size…

does not support either of my proposals. But the photos look quite a bit like H. mesophaeum, as seen on Mushroom Expert.

What was the collection date for these? I’m assuming terrestrial mushrooms are not currently occurring in the southern Adirondack region.
