Since Lycopodium spores are under discussion so much recently, it seems worth pointing out that another potential source of this material might be your local pharmacy. The spores are often used to lubricate "dry" condoms during the manufacturing process. Concerned about the potential allergenic potential, though, a number of manufacturers have switched to non-botanical lubricants. Ansell us one of them. There was a paper in Economic Botany about this, probably in mid-1989.
