It's hard to believe that a mushroom could be so bright. I almost needed sunglasses to photograph this one. I believe it is a Waxcap (Hygrocybe of some sort. I am thinking it is Hygrocybe punicea. Scarlet Waxy Cap is one of the English common names for this mushroom. I found this mushroom on one of our cut trails that we have on our property in Southern Ontario near Brantford, Ontario.
