Panthercap?

Growing near this other fungi spotting: http://www.projectnoah.org/spottings/429056030 the discolouration on this mushroom seems more dark brown rather than the reddy-brown I expect from A. rubescens. Possibly due to the lack of moisture in the mushroom and surrounding area since it was hot and dry for the previous few days. Amanita rubescens is edible but reportedly confused with highly poisonous species like Amanita pantherina. A. rubescens is the only similar one that 'blushes', hence the common name
