Holy Mario Bros. Bruce, it's a super mushroom

Many a far flung year ago, this mushroom was crushed and put into a bowl of milk, to be set aside to draw flies, ibotenic acid is the fly killer in these mushrooms. More than likely that is where Fly Amanita origniated as the name or fly agaric.

Don't know exactly where you found this one but wet knees are common when photographing these mushrooms for the most part but I have found that they mostly are found around conifers and are symbionts of the same. They are also pretty much a cosmopolitain fungi, that having to do with the distribution of pine tree seedlings worldwide I believe. Universal veil remnants on the red cap seem to be the most striking for ID purposes but there are other features to look for concerning postive ID as well of the species.
