During the Past 36 years, North American Ethnomycologist John W. Allen has studied, collected and photographed entheogenic (‘magic') mushrooms from various countries (i.e., North, Central America, Australia and New Zealand, Bali, Indonesia, Malaysia, India, Burma, Thailand, Cambodia and Vietnam). Additionally Mr. Allen has also photographed mushrooms in some European countries.

Mr. Allen is also the author of 11 books including Magic Mushrooms of the Pacific Northwest [First published in July 1976 and became Out of Print in October 2011. In 1997, 12 colored photographs were added to the centerfold of the field guide. By November of 2007, this small field guide had sold more than 103,000 copies]. Even more were sold between 2008-2011. The second field guide went from poster to packets of identification cards and then into a ringlet binder. That was the Safe-Pik Mushroom Identification Guide, long out of print since 1985. Dr. Andrew Weil wrote the forward (see above photograph for the field guide. This latter publication is currently available on the Internet web-site at

Mr. Allen was hired as a Research Associate to Dr. Mark D. Merlin of the University of Hawaii where he worked along with Dr. Merlin as a researcher and presented several lectures on entheogenic mushroom use for Dr. Merlin’s Biology 440 [Psychoactive Drug Plants] class. Mr. Allen was also helped Dr. Merlin’s rewrite the first draft for the re-issue and new edition of his book "Man and Marijuana: A History of Hemp." The new title and co-author read as Cannabis: Evolution and Ethnobotany by Robert C. Clark and Mark D. Merlin. 17 years since I stopped my work on it and it was then shelved for 17-years. Mr. Allen also wrote and edited two chapters on the many uses, descriptions and distribution of plants on Chuuk and Yap Islands in Micronesia, as well as rewriting to computer one of Dr. Merlin's many plant field guides for Hawaii.

Mr. Allen also along with Dr. Jochen Gartz as 2nd author and a forward by Jonathan Ott) Teonanácatl: A Bibliography of Entheogenic Fungi. At the time of publication in 2000, this scholarly research volume covered only approximately 1400 references and 700 annotations 4,000 cross-references with 400 photographs, each enlarge to 7-8 inches in height. After no contributions by Dr. Gartz in updating the data in this program, John W. Allen then between 2005, 2007, 2010 and December of 2012 brought this comprehensive bibliography currently up to 3000 references, 2306 annotations, mostly for psilocybian fungi, including 354 on Amanita species related to the Soma complex. Now there are an additional total count of more than 10,000 cross-references to the software and also new articles and never before seen photo pictorials from Conferences over the years as well as pictorials of the cultivated mushrooms of the Nederland. Furthermore there are more than 1600 colored photographs featured on the CD-ROM.

In which the author describes how the University of Michigan and it's herbarium staff first approved a loan of a small collection of Psilocybe caerulipes to the author for comparative chemical and DNA analysis with that of Psilocybe ovoideocystidiata, a species which macroscopically resembles Psilocybe caerulipes. After the author was promised a loan of these specimens, it took the University of Michigan's Herbarium staff close to a year to send a letter of denial to Mr. Allen. Approval was first promised in May of 2007 by Patricia Rogers, MICH Fungus and Lichen Collections and then after several communications between the author and the University of Michigan's Herbarium Department, both Dr. Paul E. Berry and Dr. Richard K. Rabeler, in April of 2008, without any reason, denied the authors permission to complete their research for a major paper.

In which the author debunks Letcher's book "Shrooms," as historically inaccurate, and rather badly researched with many instances of unfounded statements and references of statements which never occurred. Apparently many other mycologists and ethnomycologists have also found fault in the accuracy and chronological history as presented by this author and do not recommend this book to be taken seriously. At the same time American reviewers have debunked the book> Although the book has been well received in the European press. There is a prologue and an afterthought to this page which actually adds a few extra pages to the account of this review.

This is a good publication on my personal discoveries in the field of ethnomycology, however, the editor at Ronin Publishers failed as I was promised, to edit the final draft which caused damage to the academic value of this publication. There were 186 typos and numerous pixelated photos in the book. The Table of Contents does not link to the chapters described and the Index is also out of order as well.

Ethnomycological Journals: Sacred Mushroom Studies Vol. VIII:66-73. Exotic Forays, Seattle, Washington.
Cultivation and analysis of Psilocybe ovoideocystidiata, a new bluing species from Ohio and Bethany West Virginia is presented. Cultivation of this species was demonstrated on hardwood substrate. Analysis of both caps and stems revealed the presence of psilocybin, in most cases psilocin and always low concentrations of baeocystin. Psilocybin, psilocin and baeocystin levels varied in the bluing caps and stems of this new species. The highest concentrations of these alkaloids were found in both naturally grown and cultivated fruiting bodies of Psilocybe ovideocystidiata which, at the present moment is an indigenous species found in Ohio, Pennsylvania and West Virginia.. The relative alkaloidal content of psilocybin, psilocin and baeocystin found in Psilocybe ovoideocystidiata from Ohio was similar to that measured in Psilocybe caerulipes by Leung et al.

Exotic Forays, Seattle, Washington.
In 1998, Guzmán reported, “11 species of Psilocybe from the state of Jalisco of which 55 are now recognized from Mexico.” In that study, Guzmán described two new species, thus describing a total of 8 neurotropic Psilocybes from the State of Jalisco. Small collections of Psilocybe villarrealiae, were harvested by one of the authors (FCS) in Jalisco for herbarium deposit. Chemical analysis of the collected species was performed; including a scanning electron micrograph of basidiospores of Psilocybe villarrealiae is presented along with a photograph of the species analyzed in this study. This is the first report of the chemical analysis of Psilocybe villarrealiae and of new reported locations.

In the continuing studies began by Allen and Merlin in the early 1990s, as well as the recent discoveries of a 2nd bluing Psilocybe from SE Asia (Psilocybe antioquensis) and the presence of Psilocybe samuiensis in Kampuchea (formally Cambodia), the authors of this present study were prompted into presenting an updated report concerning the known species of neurotropic fungi found in certain regions of south and southeast Asia, Oceana and the Pacific Ocean. Previous investigations on the Thai islands of Koh Samui, Koh Pha-Ngan, Phuket and in various locales situated in Orissa, India, Kampuchea, Viet-Nam, Burma, Malaysia, Indonesia and Bali, as well as in several tourist resort locations in the Philippine Islands, indicate that three species of psilocybian fungi (Psilocybe cubensis, Psilocybe subcubensis and a complex mixture of several varieties of Copelandia species, consisting primarily of Copelandia cyanescens), are used for ludible purposes amongst foreign tourists vacationing in that region of the world. Includes cultivation, chemical analysis and SEM of SE Asian species of neurotropic fungi (Published as a Free Book online in the Free Book Section of the Maps Website at MAPS.ORG.

Two new records form Mexico and one from Cambodia of the hallucinogenic mushroom, Psilocybe antioquensis, originally known only from Colombia, are discussed. This fungus grows on soil in subtropical meadows, and is defined by its subumbonate pileus, long pseudorhiza, ovate-subrhomboid thick-walled spores, and for their pleuro- and cheilocystidiata. It belongs to section Mexicanae in the genus Psilocybe.
