with some sort of Leucoagaricus

The spore print was white

and as you noted, I initially thought they were Agaricus and tossed them before I saw the spore print. The gills did stay whitish even as they grew up.
I’m pretty sure there was no mix-up as every thing else I have is in order and I only picked a few things in that Park.

Spore print white?

You got them to grow up?
They sure look like Agaricus, and then if they were white spored I was going to say Floccularia fusca, but then you showed that the spores are dextrinoid, so that’s ruled out… so…
