Some types of Agaricus have gills that go almost directly from pale/gray to brown without a pink stage. The third photo shows gills with color unusually close to white for an Agaricus. Duggstar, how would you describe the color of the gills in photo #3? Sometimes lighting can affect the apparent color in a photo. These are really interesting. Thanks for sharing.

Dave, they were very pale pinkish grey, but they turned directly to brown as they dried.

The herbarium I sent it to said the spores were too small for it to be A. urinascens var. excellens though

"The spores on your specimen are too small to be those of Agaricus
urinascens (=excellens). I make it Agaricus macrocarpus because of its
plain white colour without scaliness, lack of colour reaction (yellow,
red) on cutting, large size and spore dimensions."
