Panaeolus oligotrophus sp. nov., a species macromorphologically resembling Panaeolus cinctulus, was collected in central Florida. Its macro- and micromorphological features are described and compared with all other known Panaeolus species. Color photos of the fruiting bodies and micrographs of key microscopic features are provided, along with an updated phylogenetic analysis. A microscopic...
Fungi produce diverse metabolites that can have antimicrobial, antifungal, antifeedant, or psychoactive properties. Among these metabolites are the tryptamine-derived compounds psilocybin, its precursors, and natural derivatives (collectively referred to as psiloids), which have played significant roles in human society and culture. The high allocation of nitrogen to psiloids in mushrooms,...
The relationship between ketamine's hallucinogenic- and dissociative-type effects and antidepressant mechanism of action is poorly understood. This paper reviewed the correlation between subjective effects defined by various psychometric scales and observed clinical outcomes in the treatment of patients with Major Depressive Disorder (MDD). Based on PRISMA guidelines, we reviewed the...

Since the 1970s, these groups have become increasingly present in nationwide Brazilian and international...
