FOREWORD
Nobody knows precisely when the first magic
mushroom emerged from the shadows of
prehistory to enter the light of consciousness.
Nobody knows when the first magic mushroom
was eaten by a human being.
Nobody knows
just who the first magic mushroom eater was. In
seeking answers to these questions, we can only
speculate. Mycophobes, however, are quick to
voice their conviction that only a fool would be
reckless enough to want to attain a higher state
of consciousness beyond the boundaries of
everyday reality. And only a fool would attempt
to do this by ingesting those odd little things that
mysteriously thrive on decaying, humid soil,
rotten wood and malodorous mounds of cow
manure.
Historically, magic, mushrooms have
been feared and hated` since antiquity: magic
mushrooms were thought to be made from
poisons that had dripped from serpents' fangs;
they were considered to be unclean emissions of
evil spirits; moreover, mushrooms were a kn
Most recreational users of Psilocybe cubensis (when grown in vitro) require a dosage of 1 to 2 gm of dried mushrooms to produce an altered state of consciousness; a clinical dosage for Psilocybe cubensis, on the other hand, had previously been reported as ranging from 3 to 5 gm of dried material. This dosage would be comparable to the amount of fungal material consumed for religious purposes in a Mazatec Indian healing and curing ceremony. In 1982, one research team "found that the level of psilocybin and psilocin varies over a factor of 4 among various in vitro cultures of Psilocybe cubensis, while specimens from outdoors varied tenfold." A fresh dosage of Psilocybe cubensis in Australia would be approximately from 1 to 2 large mushrooms weighing up to as much as one fresh ounce, or as many as from 25 to 50 small mushrooms equaling the same weight amount. Ethnopharmacologist Jonathan Ott (1976, 1993) noted that he has observed "the ingestion of from 0.5 gm to 5.9 gm dried weight (10 gm to 40 gm fresh)", of various species of Psilocybe. Dosage for Psilocybe subcubensis would be the same as for Psilocybe cubensis. Both of these latter two species are macroscopically alike. The usual dosage for Copelandia cyanescens required to induce psychedelic visual effects ranges from 1 to 3 large specimens (cap diameter c. 5 mm), or as many as 5 to l0 medium-sized mushrooms (cap diameter c. 2.5 mm); however, personal tolerance to this species may occur with continued use, and some who consume large amounts of this mushroom have reportedly ingested as many as 50 to 200 fresh specimens of various sizes. Potency Of Haymaker Mushrooms

There are more than 1 dozen species of "magic mushrooms" in Australia and New , and who gorge themselves on our tax dollars. I met Jochen Gartz shortly after the fall of the Berlin Wall at the third symposium of the European College for the Study of Consciousness (ECSC) in Freiburg, Germany. Our encounter was my first contact with a researcher from the former East Germany. Jochen Gartz's enthusiastic lecture was a truly consciousnessexpanding event, his words breaking down traditional borders and crossing over into new territory. The magic mushrooms spoke through him - with no trace of dogma or ideology - Mushroompotencychart in the tradition of true anarchy that is the hallmark of mushroom magic. What I heard was unbelievable. Jochen spoke of a "new" psychedelic mushroom and its migration. The mycelia had spread in concentric circles outward from Leipzig, jumping all political borders. Finally, when the mycelia reached West German soil, the hated Berlin Wall crumbled. Could there possibly be a connection between the evolution of the magic mushroom and the evolution of our consciousness? Could a mushroom have contributed to the resolution of our political conflicts? In the past, politicians, even popes, had their own jesters and magicians, who functioned as pressure release valves in the machinations of political power struggles. It is obvious that a country whose chancellor is being pelted with eggs, urgently needs a new breed of magician who are able to readjust reality. But today, no aspiring magician should go about this task without this book as a guide for the wondrous journey into the realm of magic mushrooms. Christian Rdtsch Figure 5 - "Anthropomorphic Beings Engaged in Mushroom Dance" 10,000-year-old rock drawing in Tassili, Sahara (Algeria) CHAPTER 1 I BELIEVE THE TIME HAS COME FOR A COMPREHENSIVE REVIEW OF NEW FINDINGS FROM THE FIELDS OF MYCOLOGY, TAXONOMY AND NATURAL PRODUCTS CHEMISTRY When R.G. Wasson, R. Heim and A. Hofmann began their interdisciplinary research program to study the Mexican species of mushrooms and their usage in Mexican mushroom cults, their efforts culminated in a 1958 landmark report that described the isolation, molecular structure and synthesis of the mushrooms' active ingredients: psilocybin and psilocin. Several years later, these substances were also identified in a species of mushroom in Europe, Psilocybe semilanceata, which became the first in a series of newly discovered species.Since then, psychoactive mushrooms from other genera have been reported with increasing frequency. As part of my analytical work dedicated to the identification of naturally occurring chemicals, I had the good fortune to be part of a research team that studied alkaloids found in a variety of mushroom species. Now I believe the time has come for a comprehensive review of new findings from the fields of mycology, taxonomy and natural products chemistry. Wasson and his successors have already provided detailed accounts pertaining to the history and study of the Me by A. Hofmann, Sandoz Pharmaceuticals manufactured about 2 kg (ca. 4.4lbs) of pure psilocybin for scientific research purposes. The results of pharmacological testing soon revealed psilocybin as an alkaloid that was perfectly safe for human subjects under controlled experimental conditions. Despite this evidence, the anti-drug legislative framework of the mid1960s firmly established an "official mycophobia", a misguided, yet entrenched policy that still prevails today and effectively prevents the scientific investigation of promising potential applications for psilocybin and other alkaloids. At the same time, mycological and biochemical research studies have shown that psilocybincontaining mushrooms thrive all over the world and can be found on all continents. These mushrooms are no different from any other mycoflora and must not be excluded from scientific investigation because of their alkaloid content. In addition to overall variations in value systems across cultures, individuals tend to develop their own personal attitudes towards mushrooms in general. Oftentimes, the evolution of specific opinions about mushrooms can be traced back to childhood events, even though such early experiences seldom account for the development of prevailing biases and value systems later in life. I recall an incident from my own childhood, which occurred when I was about five years old. I was playing in a grassy meadow, when a girl pointed to a brown mushroom and earnestly explained that it was inedible and poisonous. While I have never forgotten this encounter, I did grow up to become a devoted mushroom enthusiast. On the other hand, a different childhood event has left me with the vivid memory of discovering a landfill virtually covered with vast numbers of gilled bluing mushrooms and the sense of awe I experienced contemplating this sight. In general, the unusual characteristics of these mushrooms are most likely responsible for strong impressions formed early in life, which then may develop into various attitudes or beliefs later on. An enduring personal interest in psychotropic mushroom species can serve to amplify or diminish mycophobic as well as mycophilic dispositions, depending on the influence of other factors. After all, judgments about the benefit or folly of deliberately altering one's state of consciousness are also colored by individual preferences, biases and opinions. The following chapters are meant to illustrate this diversity of attitudes towards psychotropic mushrooms. Descriptions of planned and involuntary experiments with specific mushroom species offer convincing evidence that the effects of psychoactive mushrooms are open to many possible interpretations.

Australia's beef cattle can be found in the coastal areas of Queenslandglasgow to pick to around mushrooms pick
More than half of Australia's beef cattle can be found in the coastal areas of Queensland and New South Wales; and the 20 to 30 inch (500-750mm) rainfall belt of Queensland, New South Wales and Northern Victoria, generally provide adequate climatic environments for the growth of psilocybian mushrooms, especially after heavy rains. It has been suggested that "Psilocybe cubensis was introduced into Australia accidentally by early settlers along with their livestock." This same spore dispersal mechanism also probably applies to Copelandia cyanescens, Panaeolus subbalteatus and several additional species known to occur in or around the dung of other ruminants. This includes Psilocybe semilanceata and the non-hallucinogenic "haymaker's" mushroom Panaeolina foenisecii. While cattle are raised in all Australian states, as well as in the central lowlands, recreational users have been known to export these psychoptic species to various areas in Australia from areas where they were collected. In the case of New Zealand, hereafter referred to as NZ, cattle are the primary source for Copelandia cyanescens, but the "liberty cap" mushroom Psilocybe semilanceata only grows in the manured soil of four-legged ruminants and not directly from manure (Jansen, Pers. Comm., 1988). The identification section of this guide documents reported locations for more than 1 dozen species of psilocybian mushrooms in Australia and NZ which most likely have been used at one time or another for recreational purposes. The question of dosage is often confused by the variation in the source of the hallucinogenic mushroom species which is consumed. ulinary
mushroom bears no
resemblance, either in size or form, to Inocybe
aeruginascens. Overall, however, these
unfortunate cases have also contributed to our
understanding of mushroom biochemistry.
In
shroom dose chart this context, I want to emphasize
once more that
Brown Mushroom On Cow Dung In New Mexico the hallucinogenic varieties
among the Inocybes can easily be mistaken for
those muscarine-producing Inocybe species
that are extremely poisonous.
As part of his investigation of the
Psilocybe genus, Guzman noted a common
trait among the hallucinogenic species, in
addition to the bluing reaction: a flour-like
smell or taste. Apart from the inherent
subjective nature of our sense of smell and
taste, a common odor is a trait that definitely
does not apply to the European species (also
see Chapter 3.2).
Mycophile or Mycophobe?
There are reports from the Western
United States about people with expert
knowledge of Psilocybe semilanceata -
devoted mushroom hunters who can identify
the species with drill and accuracy. At the
same time, however, these experts cannot
identify easily spotted common table
mushrooms, nor are they able to differentiate
the Agaricus species (champignons) from other
mushrooms, even when these species grow on
the same pasture. Such individuals, then, are
not interested
Brown Mushroom On Cow Dung In New Mexico in species other than Psilocybe
semilanceata. In my opinion, this attitude
reflects a rare combination of mycophilia and
mycophobia.
A mushroom's spore dust provides
important information needed to determine
identity. A spore print is left by the gills when
the cap is placed on black or white paper
(depending on spore color). As the process
takes several hours, a glass vessel must be
placed over the cap to prevent drying. While
useful, information obtained from spore
analyses has its limitations, For instance,
spores derived from mushrooms Hydroponics Shrooms belonging to
different genera may have the same color, but
reveal basic differences under the microscope.
There is also a high degree Magicmushroomsgalway of similarity among
spores from different Psilocybe species. Thus,
the only way to prevent grave errors and
potentially deadly intoxications is to rely on
experienced experts for mushroom
identification, a process that must include
analysis of available ecological data.
CHAPTER 5
THE BLUING PHENOMENON AND METOL
TESTING: REALITY VS. WISHFUL THINKING
As previously discussed in Chapters 3.1
and 3.7, the bluing reaction is characteristic
of species that produce psilocybin. Still, for
unknown reasons, some species or samples
belonging to a genus that usually turns blue
may not always change color, regardless of
psilocybin content. Among the species that I
have examined, Psilocybe bohemica
displayed the most impressive bluing
reaction.
The caps of this species stain very
quickly in reaction to pressure.
Other species,
such as Psilocybe cubensis (Earle) Sing.
have stems that develop very intensely blue
stains, while their caps do not exhibit the
bluing reaction. By contrast, Psilocybe
n the U.S.)
contribute to the therapeutic process; they may
even be the sole source for future progress.
Under these conditions, stereo music also
significantly deepened the intensity of the
experience. It appears that these kinds of specific
experiences may also account for the remarkable
success of treating terminal patients with LSD to
ease their fears in the face of death and to reduce
even Magic Mushrooms Galway the most severe forms of pain. In many such
cases, symptoms disappeared entirely, and relief
from pain and anxiety that Shrooms Online continued even after the
drug's acute effects had worn off. A book by S.
Grof provides a compassionate analysis of such
successful treatments, which serves to
shroom dose chart
underscore the fact that Psilocybe Subaeruginosa Wood Types systematic efforts to investigate these particular therapeutic benefits have only just begun. So far, LSD has been the most widely studied substance in terms of easing the suffering of terminally ill patients, as well as dipropyltryptamine (DPT), a synthetic drug structurally similar to psilocybin that is active only when administered by injection. Below, a young woman from Switzerland gives a detailed account of her second mushroom experience. Her first experiment, with Psilocybe cubensis, had already introduced her to the realm of mystical experiences. For her second journey, she used 20 Psilocybe semilanceata mushrooms as part of a group ritual and achieved transcendence. A remarkable feature of her account is that the presence of an experienced guide was needed to realize the full potential of this visionary quest. "1 sat down next to another participant, seeking to connect with others in preparation for my journey. We proceeded to eat the fresh mushrooms. The room grew quiet and lovely music began to play. The mushrooms's effects came on much faster than they did during my first experiment. Twice I tried to establish closer contact with my fellow participant, but he was very nervous, and no source of reassurance for me. psilocybe semilanceata romania I was seeking my spiritual companion, but did not find that person among the present group. I became a figure in a long, white robe, wandering aimlessly among the columns (Greece?), still searching. My gaze lingered briefly on the wall next to the door and I saw faces and figures appear and vanish, but they did not hold my interest. It was hopeless.I continued my aimless roaming, and I was on the material plane, which I wanted to leave - had to leave.
Suddenly, I found myself with one of the guides, who wanted to help me. I stared off into the distance, longing to be free of the material plane, but unable to do so. For a long time, I failed to connect with the guide; our two worlds were just too different. Suddenly I sensed that he wasn't able to look at me directly. The path by which to reach me runs through my eyes, because only they are truly alive. I asked him to help me on my way and invited him to look into my eyes. I felt as if all life energy was draining from my bo Most users of the psychoactive visionary mushrooms have very little knowledge of their scientific names. Instead, they have given their favorite species local epithets which are commonly used by those who collect and ingest them. Some of these popular names are also known and applied by users outside of Australia and NZ. "Magic Mushrooms" is the most common term applied to any mushroom which contains psilocybine and/or psilocine. It was invented by a Life Magazine editor in l957 ( see Wasson, l957). Psilocybe cubensis is known in Australia as "golden tops", "gold tops" or sometimes "gold caps." The Australian epithets may have been given to this species by members of a local, drugusing group of surfers which frequented the Gold Coast region of Eastern Australia; however, some of these names have apparently been used to describe several different species of Psilocybe by users in Australia (see Allen, 1997). As mentioned above, Psilocybe cubensis is not known to occur in New Zealand. Those who ingest Copelandia cyanescens, known in Australia and New Zealand as "blue meanies", also refer to this species as "Blue Legs", "golden tops" or "gold caps". The latter two nicknames, as well as "dimple tops" and "cone heads", are common terms applied to Copelandia cyanescens in the Hawaiian Islands; and some of these same popular names have also been used by visiting surfers from both New Zealand and Australia, to describe the macroscopic characteristics of Copelandia cyanescens. These same surfers visiting Hawaii's North Shore have reportedly ingested mushrooms prior to surfing, as do many of the locally based surfers in Australia and NZ. , and who gorge themselves on our tax dollars. I met Jochen Gartz shortly after the fall of the Berlin Wall at the third symposium of the European College for the Study of Consciousness (ECSC) in Freiburg, Germany.
