Psilocybin Production
The method for making a spore print is as follows. A mushroom  with its cap fully opened and its gills exposed is selected. With a  sharp, sterilized blade the stem is cut off as close to the gills as  possible. The cap is place gills down on a clean, white sheet of paper;  on a sheet of glass that has just been swabbed with alcohol; or on two or  four sterilized microscopic slide glasses. The cap is covered with a  clean, inverted bowl or bell jar for 24 hours to prevent drying of the  cap and introduction of foreign organisms.  If a good spore print has not  formed after this time, the cap is tapped lightly with the flat side of a  knife or spatula. This should shake loose many spores. If the print is  made on glass, it is covered with another glass sheet immediately after  removing the cap in order to prevent contamination. If microscopic slides  are used, two slides are placed face to face and the edges are sealed  with tape. If paper is used, it is folded several times so that the print  is well inside.
