The type of Scleroderma stellatum from Brazil exhibits a sharp echinulate, dark brown peridium, and the type of S. bermudense from Bermuda has a peridium that is loosely woven and fibrillose, whitish to pale brownish. These characters indicate two independent species. This information is contrary to that of Guzmán in 1970, who interpreted S. bermudense to… (More)

Hallucinogenic Mushrooms in Mexico: An Overview. Psilocybe, with 53 known hallucinogenic species in Mexico, is the most important and diverse group of sacred mushrooms used by Mexican indigenous cultures. Psilocybe caerulescens, known by the present-day Nahuatl Indians as teotlaquilnanácatl, is hypothesized to be the ceremonially-used teonanácatl mushroom… (More)
In Mexico there are more hallucinogenic species of Psilocybe than in any other part of the world, with 54 species of that genus, of which 44 are hallucinogens. The great indigenous traditions and knowledge of edible, medicinal and sacred species of fungi are discussed with respect to their influence on the development of modern mycology in Mexico. Important… (More)
The subtropical Japanese bluing mushroom Psilocybe subcaerulipes, described by Hongo, has several synonyms: P. argentipes by Yokoyama (also from Japan), P. taiwanensis by Guzman and Yang (from Taiwan), and P. thaizapoteca by Guzman, Ramirez-Guillen, and Karunaratna (from Thailand). The study of the holotypes and others specimens of these mushrooms shows… (More)
Pleurotus opuntiae is an important mushroom from xerophytic temperate regions of Mexico, as parasite or saprobe on Agave and Opuntia. Discussions on the taxonomic relationships of P opuntiae with P djamor, P. agaves, P. levis, and P. yuccae are presented, of which P. agaves is a synonym of P. opuntiae, and P. yuccae is a synonym of P. djamor. This latter… (More)
This paper is a review of the new studies or new explanations of the hallucinogenic mushrooms, regarding their diversity, history, traditions, and problems in their recreational use, new taxonomic studies, and their modern applications in medicine, all of them since the 1970s to the present.
Five new species of Psilocybe from the Caribbean are described: P. caribaea, P. egonii, P. subpsilocybioides, P. zapotecoantillarum and P. zapotecocaribaea. All except P. zapotecocaribaea, which is known only from Martinique, are native to Puerto Rico. Psilocybe guilartensis, previously described from Puerto Rico, is the most commonly collected species of… (More)
