Notes on 113 fungal taxa are compiled in this paper, including 11 new genera, 89 new species, one new subspecies, three new combinations and seven reference specimens. A wide geographic and taxonomic range of fungal taxa are detailed. In the Ascomycota the new genera Angustospora (Testudinaceae), Camporesia (Xylariaceae), Clematidis, Crassiparies(More)
The analysis of twenty species from seven genera of Pacific Northwest mushrooms revealed psilocybin (and in some cases psilocin as well) in seven species from three genera. The species found to contain psilocybin (and psilocin) varied from one collection to another by more than a factor of seven in amount present. Total psilocybin and psilocin levels in(More)
Rapid quantification of psilocybin and psilocin in extracts of wild mushrooms is accomplished by reversed-phase high-performance liquid chromatography with paired-ion reagents. Nine solvent systems and three solid supports are evaluated for their efficiency in separating psilocybin, psilocin and other components of crude mushroom extracts by thin-layer(More)
Analysis of Psilocybe cubensis (Earle) Singer grown in controlled culture showed that the level of psilocin was generally zero in the first (or sometimes even the second) fruiting of the mushroom from a given culture and that the level reached a maximum by the fourth flush. The level of psilocybin, which was nearly always at least twice the level of(More)
Morphological and molecular phylogenetic studies of true morels (Morchella) in the Canadian province of Newfoundland and Labrador resulted in the discovery of two undescribed species in the M. elata clade that we initially distinguished by the informal designations Mel-19 and Mel-36. The latter species, also collected in New Brunswick, Canada, is hitherto(More)
The retention properties of PCBs (polychlorinated biphenyls) were examined in the mussel (Mytilus edulis) over a period of 89 days. Mussels were transferred from a site of relatively high PCB contamination to a site of relatively low PCB concentration in Puget Sound, Washington. Retention of PCB components increased with increasing chlorine content.(More)
