Meadow mushrooms

Here are some shots of what I think are Brown meadow mushrooms (Agaricus cupreobrunneus). The caps on these seem to vary depending on which tree I find them under. They have no yellow stain with a slight reddish stain around the gills. If you look in Arora's pocket guide on page 112 the staining on the stipe and near the gills is exactly what I am seeing. Note closely the coloring on the caps. These were found in a pasture that used to hold cows. If you can find a button that hasn't opened yet the gills are very pink. Once the gills open up they start to take on a brown color. They smell just like the store bought variety.

On to the Pholiota destruens. These grow on the cottonwood trees along the greenbelt. They are not edible.
I have a couple of closeup shots.

Note how the stipe turns 90 degrees.

Thanks all for now.
