e use of ayahuasca among rubber tappers of the Alto Juruá

April 8, 2016 Domingos Bernardo Gialluisi Da Silva Sá, Christian Frenopoulo, Matthew J. Meyer 1 citation

The chapter reviews a decade of non-policing government monitoring of ayahuasca use in Brazil, where the brew is known as Daime, Santo Daime, or Vegetal. It argues that cost-benefit analysis of drug policy is fundamentally resolved on the cultural level, rejecting a simple mechanistic view like pharmacological determinism. The Uniao do Vegetal (UDV) sees ayahuasca not as an end in itself but as a vehicle in a path of sacrifice and austerity, while it remains an important instrument for achieving spiritual goals for the communities that use it. The chapter advocates for adopting or modifying just public policies directed to drugs, based on this pioneer experience.

Panaeolus oligotrophus : A new species from central Florida, with notes on Panaeolus pumilus and Crucispora rhombisperma

Mycologia October 7, 2025 Scott Ostuni, Pietro Voto, Joshua Birkebak et al.

A new species of fungus, Panaeolus oligotrophus, was discovered in central Florida. It looks similar to Panaeolus cinctulus but grows in nutrient-poor sandy soil, a rare habitat for this genus. Its physical features and DNA were analyzed and compared with other Panaeolus species. The study also found that the type specimen of Panaeolus pumilus is actually the same species as P. cinctulus. Additionally, another species, Crucispora rhombisperma, was reclassified into the genus Panaeolus and renamed Panaeolus rhombispermus because of its unusual spore shape. The potential for psilocybin production in the new species was checked by sequencing its genome.
