Attached are some pictures. I did not pick the mushroom(s), and thus have no picture of gills or a spore print for you. Curious as to whether you could identify based on just these pictures. Amanita muscaria? Amanita flavoconia? Other? Found camping in Central Ontario. Under large tree, either oak or pine (can't remember :/). Grew very quickly due to wet conditions.
I think that it is Amanita muscaria var. formosa. Amanita flavoconia is smaller (cap under 10 cm, which I don't think these are) and doesn't have the series of "rings" at the base of the stallk.
