Here's an idea for an experimental method. Would alkaline quidding of mushroom powder perhaps do the trick? A pinch of lime, a pinch of cornstarch and a pinch of powdered shrooms might be worth a try. I would suggest mixing with the lime immediately before quidding because psiloc~in becomes unstable in alkaline environments.
Chitosan is derived from chitin, and chitin is the principal structural material of mushrooms:
Quote:Chitosan is a linear polysaccharide composed of randomly distributed β-(1→4)-linked D-glucosamine (deacetylated unit) and N-acetyl-D-glucosamine (acetylated unit). It is made by treating the chitin shells of shrimp and other crustaceans with an alkaline substance, such as sodium hydroxide.
Quote:Chitin is a long-chain polymer of N-acetylglucosamine, a derivative of glucose. This polysaccharide is a primary component of cell walls in fungi, the exoskeletons of arthropods, such as crustaceans and insects, the radulae of molluscs, cephalopod beaks, and the scales of fish and skin of lissamphibians. The structure of chitin is comparable to another polysaccharide, cellulose, forming crystalline nanofibrils or whiskers. It is functionally comparable to the protein keratin.
Obviously, pure chitosan is readily available for purchase, but the intrepid (cheapskate) researcher will see that any one of a number of naturally-occurring materials (insect wings?) would be a pretty good source of fairly pure chitin. A simple pre-treatment with sodium - maybe even calcium - hydroxide followed by neutralisation should furnish some level of deacetylation. Besides that, some fungi produce a certain amount of chitosan as it is.
This looks like a good read for would-be chitosan nerds:

The field acts on the observer and puts him in a privileged position vis-à-vis the universe. From this position he has access to the realities which are ordinarily hidden from us by time and space, matter and energy. This is what we call the Great Work."
