| An inquiry into the field identification of a
psychoactive agaric commonly referred to as the "Weed Mushroom," Panaeolus
subbalteatus. This following paper is meant to be used only for the macroscopic and mycological identification of Panaeolus subbalteatus and not for any illicit activity. Panaeolus subbalteatus is an entheogenic fungi which contains the psychomimetic indole alkaloids psilocybine, psilocine and baeocystine. Historically, this fungi is referred to as the "Weed Panaeolus." According to the late mycologists, Dr. Rolf Singer and Dr. Alexander H. Smith, it is "one of a number of weed fungi [like crab grass is to grass] found spontaneously like weeds in beds of the cultivated commercial white mushroom Agaricus bisporis [your common grocery store mushroom or champignon as the French refer to them]." During the past 100 years Panaeolus subbalteatus has been referred to by many different binomials, including the "poisonous mushroom" Panaeolus venenosus. Other mycologists have named it Panaeolus rufus, Panaeolus semigloblatus, and Panaeolus variabilis and some lame Europeans have referred to it as Panaeolus benanosis. It may even be conspecific with Panaeolus papillionaceus. The latter species is also referred to as the "butterfly" mushroom. Since the early 1900's, numerous intoxications occurred when P. subbalteatus was consumed as an edible variety. Early reports regarding accidental inebriations from Panaeolus species date back to the Chin dynasty (2nd century a.d.) and the 11th century in Japan. Many ancient Chinese herbal medicine books list Panaeolus species as the cause of a laughing sickness and describe cures under the heading of "Cures for the laughing sickness." A remedy for this laughing malady requires a potion consisting of an infusion of water which has been filtered through top soil. The inflicted party would drink the potion to alleviate the intense laughter after accidentally or purposely ingesting psilocybian fungi. Panaeolus subbalteatus is a cosmopolitan species found all over the
world. It is common in the dung of cattle and composting hay and/or
haystacks. Other habitats include lawns, open fields and riding stables.
Its season extends from late February through early June and again in
August and September. P. subbalteatus fruits abundantly in rotted haystacks
in the Willamette Valley in Oregon. In the Hawaiian archipelago, P.
subbalteatus is abundant in cow manure at the 3000 foot elevation above
and below Kula highway on Maui Island. |
| Black spored fungi of the genus Panaeolus and Copelandia
species both belong to the family of psilocybian fungi known to contain
the hallucinogenic indole alkaloid psilocybin and psilocin. Black-spored
fungi of the genus Coprinus and Anellaria may contain some tryptamine
derivatives but do not possess either psilocin or psilocybin. Coprinus
species are known as inky caps because their caps are deliquesce; that
is, after appearing in the early morning dew their caps began to melt
right on down their stems, usually leaving a glob of black goo where they
once grew. Like Panaeolus subbalteatus, Coprinus species also fruit well
in rotted hay and lawns. Although Anellaria is a dung fungus it does not
resemble Panaeolus subbalteatus whatsoever.
Since I was aware of the habitats of these various families and knew of their seasons, I was able to determine that I could always find Panaeolus subbalteatus anywhere in the world. For a while after 1970, Panaeolus subbalteatus had become the third most popular free high mushroom in the United States after Psilocybe cubensis (the "gold top") and Psilocybe semilanceata (the "liberty cap"). Andrew Weil wrote about the popular use of Panaeolus subbalteatus in the Pacific Northwest in his book The Marriage of the Sun and Moon. In 1976, Dr. K. W. Jacobs of Mississippi reported that "Panaeolus subbalteatus was gaining quite a reputation in Mississippi and adjacent states and could possibly be the second most widely popular mushroom being consumed for its psychoactive properties in the Southeastern United States in use today." Jacobs based his statement on inaccurate information obtained from a mushroom identification manual by F. C. Ghouled. By 1976, Jonathan Ott, Jeremy Bigwood, Gastón Guzmán and Andrew Weil, all described Panaeolus subbalteatus as a popular recreational drug and in 1977 Andrew Weil wrote that "during the spring and summer months when the "liberty caps" are not available, Oregonians can use another variety of psilocybian mushroom in the genus Panaeolus. It is easily picked in quantities on piles of rotting hay in manured cow fields in the Willamette Valley. This mushroom is twice as fleshy as the "liberty cap", even though it is less potent. The dosage (when fresh) for both species, is similar depending on the size of the mushroom. Usually about twenty to forty mushrooms are sufficient for producing the desirable effects similar to that of the Psilocybes and Copelandias." Weil also mentioned that "moreover the quality of the effects are not as good. When fresh it has been known to produce symptoms of mild toxicity, and sometimes nausea has been known to occur. I felt uncomfortable and quite restless after eating this variety. Drying them seems to curb some of the toxicity but not all of it. It is also not as visual in context as [are] other varieties. None the less it is quite popular in the warmer months." Although Dr. Weil's experience with this species was not up to his expectations, clinical research on human volunteers has proven that Panaeolus species are more tranquil and less toxic in nature to humans than their cousins the Psilocybes. A clinical dosage for Panaeolus subbalteatus would be three to five grams of dried material or one fresh ounce. This would be equivalent to the same dosage for Psilocybe cubensis. One fresh ounce of Panaeolus subbalteatus would be approximately five to thirty fresh mushrooms depending on their size. |
| Many mushroom enthusiasts may or may not be aware
of the notable bluing reaction which occurs in mushrooms containing psilocybin
and/or psilocin. The bluing reaction is an indication of the presence
of psilocybin and psilocin in several genera of wild mushrooms. Laboratory
and field research has shown that when the flesh of a mushroom which contains
psilocybin and psilocin is damaged, scraped, broken or bruised, whether
from natural elements (wind or rain, falling leaves, insects, slugs, animals,
etc.) or from human handling, an enzyme occurs causing the bruised section
of the mushroom to turn from an olive green to blue green color. Oxygen
is the cause of this color change and is common in many species of psilocybian
fungi.
While there are many species of fungi which are blue naturally, these naturally occurring blue fungi may be poisonous and/or toxic to human consumption. One such species is Boletus cyanescens. However, all Boletus fungi have a porous sponge like section under their caps and do not possess gills like the psilocybian species. Dr. Rolf Singer originally "defined Panaeolus subbalteatus as not bluing in the stipe [stem] because of the brown coloration [of the stem]." However Dr. Singer did notice the occurrence of some mild bluing in the sclerotia. Additionally, Drs. Rolf Singer and Alexander H. Smith were the first to note that the "blue color of the sclerotia and the base of one single specimen [of Panaeolus subbalteatus] were the same as they found in Copelandia cyanescens and the bluing of the Psilocybes." In 1963, Dr. Roger Heim, a French mycologist observed "some bluing to be present in some specimens of laboratory grown cultures of Panaeolus subbalteatus." As I mentioned earlier, The specimens of Panaeolus subbalteatus which I collected on Maui in Hawaii all exhibited a very intense blue staining reaction, yet the hay varieties and mainland dung varieties apparently are lacking in the bluing phenomena. In 1976, Jonathan Ott reported that "psilocin and psilocybin have been detected in Canadian specimens of Panaeolus subbalteatus." Mexican specimens were also shown to contain psilocybin as were Italian collections. Recently this mushroom was also identified from Alaska. In 1977, Repke, Leslie and Guzmán found baeocystin and norbaeocystin in Panaeolus subbalteatus. They based their findings on studies of six different collections of Panaeolus subbalteatus collected in Maryland, Oregon and Washington states. Leslie also bioassayed a collection which was stored for more than a year and reported a most rewarding experience. I hope that this paper will provide its reading audience with some knowledge of understanding of the growth, development and habitat of Panaeolus subbalteatus and that those who seek find what they search for. |
