Fungal material: Cultivated mushrooms: Psilocybe semilanceata (FR.) Kumm from horse manure compost (Gartz 1991); Psilocybe cubensis (Earle) Singer grown on cow dung/rice grain mixture (Gartz 1989a); P. bohemica from rice grain/water (Gartz and Mueller 1989; Gymnopilus purpuratus (Cooke and Mass) Singer from rice grain/saw dust medium (Gartz and Mueller 1990, Gartz 1991).
Naturally grown mushrooms: Panaeolus cyanescens (BK & BK) SACC. (leg. Oahu, Hawaii 13.11.88); Inocybe aeruginascens Babos (leg. Potsdam 20.05.1987); P. bohemica Sebek (leg. near Sazava, Czech Republic 15.11.89).
All basidiocarps were dried at room temperature. Possible present residual water was removed from the mushrooms by freeze-drying. Voucher speciments of each species have been deposited in the herbarium of the Univeristy of Leipzig (LZ).
Extraction: (Samples (0.01 - 0.1 g) of dried ground mushrooms were extracted with 5 to 20 ml of methanol for 0.5 to 12 hours by using a magnetic stirrer at room temperature. Under equal conditions the mixtures with aqueous acetic acid (Casale 1985) and a queous ethanol (psilocin) and methanol (psilocybin) (Kysilka and Wurst 1990, Wurst et al. 1992) were used for extraction of the same batch of mushrooms. In the cases with aqueous alcohols as solvent a different extraction time for psilocybin (10 min) and psilocin (160 min) was performed (Kysilka and Wurst 1990). By using of dilute acetic acid the solution was placed in a boiling water bath for 10 min after extraction and anaysis and was then analysed 10 min after extraction and analysis and was then anal ysed again (Casale 1985).
The filtration and analysis of the indole derivatives by using HPLC and TLC were described elsewhere (Gartz 1987, Semerdzieva et al. 1986, Wurst et al. 1992). An analysis of the extracts for enzymes of the phosphatase type was also carried out (Weber a nd Horita 1963).
