These look much different from the Pan subs I've encountered. I don't think I've ever seen any turn their caps up that much although they appear to have a hygrophanous cap (the color rings caused by variations in moisture).
The gills don't look right, Pan subs should have nearly black gills when they're aging due to the jet black spores they release. It would definitely help if you could get the spore color. Rusty brown is bad.
They do seem to be bruising some green/blue... what are the three rules Stamets says for identifying? Black spores, blue bruising, seperable gelatinous pellicle, I think.
My intuition says no, the ones I've found have always looked more like this.
