Cone-dwelling agarics from British Columbia were surveyed. Strobilurus lignitilis, S. occidentalis and S. trullisatus comb. nov. are redescribed. Differentiation of these species is based mainly on pleurocystidial characteristics which are illustrated. Strobilurus lignitilis is reported on Douglas Fir and pine cones for the first time. Its range is extended to British Columbia, Ontario, Quebec, and Idaho. The range of S. occidentalis is extended south from Alaska to southwest British Columbia. Strobilurus trullisatus is reported on pine cones as well as Douglas Fir cones. Its range has been extended to British Columbia California and Idaho. All three species are described from cultures. Strobilurus trullisatus produces fertile basidiocarps in culture. A key to the described species of Strobilurus is given. Baeospora myosura is reported from British Columbia, Alaska and Idaho on Engelmann and Sitka Spruce cones. Conidia are formed by clampless hyphae in cultures of B. myosura. The following basidiomycetes have been found on cones in British Columbia: Auriscalpium vulgare on pine and Douglas Fir cones, Mycena epipterygia on Mountain Hemlock cones, M. sanguinolenta oil Douglas Fir and Western Hemlock cones, Mycena sp. on Sitka Spruce cones, Ramaria pinicola on Douglas Fir cones, and Xeromphalina cauticinalis on Western White Pine cones. / Science, Faculty of / Botany, Department of / Graduate

I. Psilocybe cubensis was cultured successfully in two media. Medium A was devised by Catalfomo and Tyler and Medium B was a modification of a medium which has been used for ergot alkaloid production by Claviceps purpurea. Only when the fungus was kept on Sabouraud agar plates.did it subsequently produce psilocybin when transferred to liquid media. A quantitative time-course study of psilocybin production in the two media was carried out. Maximal production appeared on the fifth day. The activities of an acid phosphatase, acting on psilocybin, were measured from mycelia grown in the two media. Enzyme activity from the A culture was very high and a blue color caused by oxidation of psilocin formed in five minutes. The effect of adding L-tryptophan on alkaloid production as well as the fate of tryptophan-C¹⁴ was also investigated. Tryptophan stimulated significantly psilocybin production in the very beginning in the B medium. The degradation of tryptophan was different in the two media. It was converted to kynurenine and anthranilic acid in A medium and to tryptamine in tryptophan added B medium (B' medium). Radioactive D,L-tryptophan side chain labeled, gave labeled psilocin and psilocybin. Potassium deficiency decreased psilocybin production while a potassium supplement had no effect. The fungus did not produce polyacetylenic compounds in the medium but ergosterol was detected as a major acetate derived metabolite when the fungus was kept on MYP agar plates and transferred subsequently to liquid media. Psilocin has very slight antibiotic activity against Candida albicans whereas psilocybin has none. II. Eight species of Lentinus and Lentinellus were investigated for the occurrence of a phenol-O-methyltransferase. Only Lentinus lepideus and Lentinus pbnderbsus showed enzyme activity in both light and dark conditions. The specificity of the enzyme for a number of substrates was also examined. Of six compounds tested, methyl p-coumarate, methyl caffeate and methyl ferulate.served-as substrates. The products of enzymic activity were identified-by radioautography. / Science, Faculty of / Botany, Department of / Graduate
