I *believe* these are Russula Fragilis. They do look exactly like photos someone else has on the web of russula fragilis mushrooms. I am not positive, though. If someone knows a way to tell for sure, please let me know!
These Russula Fragilis were photographed at Purgatory Chasm.
Please do not eat any of the items I mention on the site! I am not an expert. Always talk with an expert before eating any mushroom or plant.
