check out rhodiums site (i think this is where swim found the procedure) IT has to do with i think extracting with CHCl3 (chloroform). don't know the rest.

This is the procedure Hoffman used. I found it over on hyperreal. I had a dream a while back that this worked real well.
Dry the mushrooms.
- This important step is most likely to cause the greatest
loss of yield depending on how it is done.
Crush or grind the dried carpophores or mycelium to a powder.
Shake and allow to stand (e.g. 30 mins) in chloroform. Use maybe
twice the dry weight in solvents at every step, or enough to
well cover the powder.
Filter and discard the chloroform.
SHake the reidue and allow to stand with acetone.
Filter and discard the acetone.
Shake residue and allow to stand with methanol.

Shake residue and allow to stand with methanol.
Filter.
Shake residue and allow to stand with methanol.
Filter.
Discard residue.
Combine methanol extracts.
Evaporate methanol to dryness, preferably in a vacuum, although
low heat will do.
This will yield a crude extract containing the active tryptamines,
suitable for most purposes.
This can be further chromatographed on cellulose etc. to give pure
psilocin and psilocybin. The recommended solvents are
n-Butanol saturated with water, and n-butanol:acetic acid:water
(24:10:10).
