Ibotenic acid will decarboxylate definately on heating, to form muscimol, I was asking wether mere drying of the carpophore would also prove enough for decarboxylation to occur, as it is desired.
I might as well post this picture I just took, such a lovely specimen, it seems quite a shame to actually uproot this fruiting body, I found it only today, and it weighs roughly 3/4 of a pound, probably the biggest I have ever seen
