Both those mushrooms can be found in abundance in Sweden during September, and Im pretty shure your right Spinner about the vikings eating them before battle. I hate Psilocybe Cyanescens because it looks so much like the sought after Cantharellus tubaeformis. Every year, many people get sick from mistaking the one for the other and using them for cooking, so I would strongly discourage anyone from eating the Psilocybe Cyanescens as they can permanently damage your liver end kidneys. Worms are disgusting, but less of a hazard to your body ...exception being the Tequila worm...damn those Sunday maggot headaches =P
