Found from spring to autumn grouped or clustered often in rings up to two feet in diameter on open ground, freshly manured lawns, straw piles, all types of compost, dung piles, and roadsides in Ontario and throughout the USA (especially in Massachusetts, Maryland, New York, Ohio, Michigan, Washington, and Oregon). Optimum growth on MEA is at 86 degrees F. It occasionally occurs as a weed mushroom in commercial mushroom houses.
PHOLIOTINA CYANOPODA:
Found in August through September solitary to clustered on lawns in such
diverse parts of the USA as New York, Washington, and Colorado.
PSILOCYBE
BAEOCYSTIS:
Found in autumn and winter, solitary, grouped, or clustered on earth,
lawns, mulch, and decomposing forest wood near scattered trees especially
conifers - in western Oregon and Washington. It does well on Agar media
at 77 degrees F. This is a potent species containing Psilocybin, psilocin,
baeocystin, and nor-baeocystin. Perhaps it is because of the latter two
alkaloids that it is the most visually hallucinogenic of the psilocybin
mushrooms. There is a report that in 1960 a six-year old boy died after
eating a large number of these mushrooms. There has never been any other
indication that these alkaloids are dangerous. Until there is further
clarification of this question, we advise that anyone using this species
proceed with caution by starting with small doses and progressing gradually
to larger ones. This is especially important when using the extracted
crude alkaloids which may contain large concentrations of the baeocystin
alkaloids.
PSILOCYBE
CAERULESCENS:
Found in the summer during rainy season, grouped or clustered but
rarely solitary, mostly in shady places on soil, sugar cane mulch,
recently turned earth or stream banks - in Alabama, northern Florida
and Mexico. The Mexican variety P. CAERULESCENS var. MAZATECORUM is
known locally as "Durrumbe", which means "landslides." There it is
often found among landslides, or near corn or coffee plantations.
The mycelium does best on MEA at 81 degrees F. Thermal death occurs
at 95 degrees F. It is almost impossible to produce carpophores
on sterilized rye medium. They can be grown on vegetable compost in dim
light, but the incubation period is long (55-85 days). Although this
species is resistant to white mold it's long incubation period leaves it
prone to other diseases. It is not one of the more potent species.
PSILOCYBE CAERULIPES:
Found in summer and occasionally autumn solitary or clustered on
decomposing logs and debris of hardwood trees (especially birch and
maple) in New York, New England states, Ohio, Michigan, North Carolina,
Tennessee and Ontario.
PSILOCYBE CUBENSIS var. CYANESCENS ..SINGER (formerly STROPHARIA CUBENSIS
..EARL):
Found from February to November in compact groups in clearings outside
forest areas, on cow dung, or horse dung, in rich pasture soil, on straw,
or on sawdust/dung mixture in Mexico, Cuba, Florida and other southern
states. It grows well on MEA at 86 degrees F. Carpophores appear in
4-8 weeks. Thermal death occurs at 104 degrees F. Carpophores larger
than wild specimens can be produced by inoculating vegetable compost in
clay pots with agar grown mycelium, casing with silica sand/limestone
mix, and incubating 4-6 weeks in daylight at 68 degrees F. It does
poorly in darkness. It is a potent mushroom and very resistant to
contaminants.
PSILOCYBE
CYANESCENS:
Found in autumn scattered, grouped, or clustered in woods, on earth,
among leaves and twigs, and occasionally on decomposing wood - in
northwestern USA.
PSILOCYBE
MEXICANA:
Found from May to October isolated or sparsely at altitudes from 4500 to
5500 feet, especially in limestone regions, among mosses and herbs, along
roadsides, in humid meadows, in cornfields, and near pine forests in
Mexico.
PSILOCYBE
PELLICULOSA:
Found September to December scattered, grouped, or clustered on humus and
debris, in or near conifier forests in northwestern USA and as far south
as Marin County, California. This is a small but potent species.
PSILOCYBE QUEBECENCIS:
Found from summer to late October scattered in shady areas at forest
edges, on sandy soil containing vegetable debris regularly inundated
by river flooding, and on decomposing wood and debris (especially birch,
alder, fir, and spruce) in the Quebec area. It thrives at lower
temperatures than other psilocybe species and produces carpophores at
air temperatures of 43 to 59 degrees F.
PSILOCYBE
SEMILANCEATA:
Found August through September often in large groups on soil, among
grasses, in clearings, pastures, meadows, forest edges, open conifier
woodlands, and on roadsides - but never on dung - in New York, northern
USA, British Columbia, and Europe. Generally regarded as one of the less
potent species, but is sometimes quite potent.
PSILOCYBE STRICTIPES:
Found in October rather clustered on soil or on decomposing wood and
debris, on conifiers and some other trees in northwestern USA (especially
in Oregon). It closely resembles P. Baeocystis, but has a longer stem.
It tends to be as visually hallucinogenic as that species and probably
contains the same or similar baeocystin alkaloids.
PSILOCYBE SYLVATICA:
Found in September and October in small compact but unlustered groups
in woods on leaf mold, debris (especially beech wood), around stumps
and logs, but not usually on them - from New York to Michigan and as
far north as Quebec and Ontario. This mushroom is small and is often
mistaken for P. Pelliculosa.
The species discussed above are only some of the more commonly known ones with hallucinogenic properties. There are recognized among the psilocybin bearing mushrooms 40 species of Conocybe usually ocuring in forests, pastures, gardens, dung areas, sandy soil, ant hills, decayed wood, and charcoal and having a cosmopolitan range; 20 species of Panaeolus found on soil and dung and having a cosmopolitian range; 40 species of Psilocybe found on soil, moss clumps and organic substrata such as dung, rotting wood, bagasse, and peat ranging from the artic to the tropics; and 9 species of Stropharia found on soil, dung and sometimes on leaf mulch and rotting wood and having a fairly cosmopolitian range.
PURE CULTURE TECHNIQUE
The most difficult part of psilocybin mushroom cultivation is the observance of the rules of pure culture technique. These are the sanitary code of mushroom cultivation. There are usually many varieties of bacteria and fungal spores in our environment; floating in the air, clinging to our hands and clothing, issuing from our mouths with every exhalation. Extreme measures must therefore be taken to keep these out of our mycelial cultures, which they would rapidly overrun. The following points should be diligently observed. Work in a clean, uncluttered, dust free room. Immediately before work wash the work table and spray the room
with disinfectants. Scrub arms, hands, and nails with disinfectant soap.
Wear simple clothing. A freshly cleaned short-sleeve T-shirt is ideal.
Gargle with antiseptic mouthwash and cover the mouth and nose with a clean
cloth or disposable surgery mask. Cover the hair with a surgical cap or
shower cap. Allow no drafts in the room. close all doors and stuff all
door jambs. Let no flies, animals, or unnecessary people in the room. Let
only sterilized equipment touch the medium or inoculum. Don't lean over
your work. Avoid all swift movements that may cause a draft. If possible
have a hood constructed around the work table or a screen or curtain
surrounding it. Be neat and keep all materials within reach. Keep all
equipment about three feet away from the work. Do not permit anyone to
enter the room while work is in progress.
STERILIZATION
All utensils used in the cultivation of mycelia must be sterilized by heat before use. Glassware must be boiled in water for 30 minutes.
Metalware used repeatedly must be held in a flame until glowing and
then allowed a moment to cool before making contact with any cultures
or specimens. When the inoculation loop has been used to transfer a
fragment of mycelium it must be flame sterilized again before touching
the next fragment. All medium containers must be sterilized after the
medium has been poured. This process is known as autoclaving. Containers
no more than half full with medium are placed in a canning type pressure
cooker. The lids of these must be loose enough to allow escape of
internal pressures. Otherwise the containers may crack. Seal the lid of
the pressure cooker. Keep the stopcock valve open. Using high heat bring
the cooker to boiling so that thick steam comes through the vent. Close
the stopcock and let the pressure rise to 15-20 pounds. (250 Degrees F.)
for 30 minutes. This should be enough to destroy any foreign spores or
lifeforms. Any higher temperature or longer period would cause the
dextrose or maltose sugars to carmelize. This would inhibit growth and
psilocybin production of the mycelium. When the autoclave period is up
turn off the heat and let the cooker cool to room temperature. Do not
release the stopcock until everything has thoroughly cooled or the
sudden change in pressure will cause the containers to boil over. Discard
any containers that have cracked during sterilization. Keep all containers
of medium at room temperature for three days to see if any foreign
molds develop. If they do occur discard the medium in the contanminated
jars and thoroughly clean and sterilize such jars before using again.
MAKING A SPORE PRINT
A spore print is a collection of spores on a flat surface. It can serve several purposes. It can be used to assist identification of the specimen by observing its color or if made on a glass slide, by studying the shapes of the spores under a microscope. Mycological identification keys include descriptions of spore prints and microscopic spore features for different species. Spore prints are also the standard method of collecting spores for later germination on agar media. A print from a single mushroom cap contains millions of spores. Many mushroom lovers are now making spore prints on paper from species available in their locales and mailing them to cultivators in other areas where such species are not found. Secret spore exchange correspondence clubs are becoming quite the vogue and will probably be more common in the very near future. A word of caution regarding this practice should be given, however. Do not assume that spores received in this manner are from the species the sender claims they are. If the sender has misidentified the specimen and the recipient cultivates and ingests mycelia or extractions therefrom, the result may be disasterous. Furthemore, I would not put it past some anti-drug fanatic to purposefully disseminate spore prints of dangerous mushrooms to amateur cultivators. This could result in sickness and death for thousands of persons.
To make a spore print take a mushroom with it's cap fully opened and gills
exposed. With a sharp sterilized blade cut off the stem as close to the
gills a possible. Place the cap gills-down on a clean, white sheet of
paper, or on a sheet of glass that has just been swabbed with alcohol, or
on two or four sterilized microscopic glass slides. Cover the cap with a
clean, inverted bowl or bell jar to prevent drying of the cap and intrusion
of foreign organisms.
Let this stand as such for 24 hours. If a good spore
print has not been formed after this time, tap the cap lightly with the
flat side of a knife or spatula. This should shake loose many spores. If
the print is made on glass, cover it with another glass sheet immediately
after removing the cap to prevent contamination. If microscopic slides
are used, place two face to face and seal the edges with tape. If paper
is used. fold it several times so that the print is well inside.
PREPARATION OF MEDIA
PDA (Potato Dextrose Yeast Agar): Wash 250 grams of unpeeled potatoes and slice them 1/8 inch thick. Wash these several times in cool tap water until the water is clear. Drain the slices in a collander and rinse once with distilled water. Cook the potato slices in distilled water until tender. Strain the cooking liquids through a flannel cloth or several layers of cheesecloth and collect the liquid in a flask. Rinse the boiled potatoes several times with distilled water, add these rinse waters to the liquid in the flask, and discard the potatoes. Add enough distilled water to the flask to make one liter. Bring the liquid to a boil and add 15 grams of agar, 10 grams of dextrose, and 1.5 grams of yeast extract. The agar must be added slowly and carefully to prevent boiling over. While the liquid is hot, pour it into petri dishes or other culture containers. Each should be filled half way.PDY (Potato Dextrose Yeast broth): PDY broth is made in exactly the same manner except the agar is omitted. Mason jars are filled half way with the hot or cool liquid.
MEA (Malt Extract Agar): To one liter of gently boiling water (distilled) add 20 grams of malt extract, 20 grams of agar (slowly, carefully to prevent boiling over), 100 mg of potassium phosphate dibasic (K2HPO4), and 100 mg of calcium carbonate. While still hot pour the liquid into the culture dishes.
EQUIPMENT
Most of the equipment described in this guide is readily available at reasonable prices. One quart size mason jars can be purchased from many stores including Sears for about $2.98 a dozen. If a large scale Psilocybin farm is being set up, a greater number of jars could be obtained from a Wholesale outlet or bought at a discount from the retailer. Pipettes, inoculating loops, petri dishes, agar, and other materials (including pre-mixed media) are found at many scientific supply houses or can be ordered from Difco Laboratories, Inc., Detroit, Michigan 48201.
If Petri dishes are not on hand, there are several other containers that
can substitute. Baby food jars 1/4 filled with agar media are excellent.
Test tubes can be filled 1/3 with hot agar medium, stopped with cotton,
autoclaved and allowed to cool while standing at a 17 degree angle. These
are known as slants and permit a maximum surface area. A wooden rack can
be easily constructed to hold slants at this angle. Baby bottles with a
steam sterilizer can be bought almost anywhere. These come in sets of nine
or ten bottles. The tip of the rubber nipple should be cut off and a wad
of clean cotton pulled through from the inside leaving about 1/2 inch
sticking out. The bottles are filled 1/3 with agar medium. After sterilizing
the bottles should be kept at a 17 degree angle. A large pressure
cooker - the type used for canning and jarring - can be used for autoclaving
mason jars of broth medium.
STARTING THE CULTURE
Upon obtaining one or more specimens of a psilocybin bearing mushroom one can begin to cultivate as much of the hallucinogen as is desired. Any part of the fungus can be used for inoculation. If the spores are used, consideration must be given to the natural life cycle of the mushroom. A single cap contains millions of spores, and any one of these will germinate in the medium to form a mycelium. But this mycelium will consist of what is known as monokaryotic tissue. Such a mycelial organism will grow for a while, but unless it mates with another compatible monokaryotic mycelium and forms a dikaryotic structure it will eventually perish. To develop a culture from spores proceed as follows: Scrape the spores from the print into about 10 ml of sterilized water. Shake well. Add 90 ml of sterilized water and shake again. There will be millions of spores in this solution. Have ready several petri dishes or other suitable containers as described previously containing sterilized agar medium. Lift the lid slightly on each container and with a sterilized pipette or syringe place a drop of this spore water on three or four different parts of the agar surface, then cover the container immediately.
Let the dish stand at room temperature for 3-5 days. Radial growths
of monokaryotic mycelium will occur at each inoculation point. When any two
mycelia have grown to the point of making contact with each other mating
(somatogamy) has taken place and within a few days these united mycelia will
have become dikaryotic organisms. Any portion of this mycelial tissue can
now be used to seed new cultures as described later.
If a portion of one of the carpaphores gathered in the field is used to
inoculate the agar, mating is not required. The tissue of mature fungus is,
of course, already dikaryotic. To avoid contamination only inner tissue is
used. Place the mushroom cap gills-down on a clean work area at least three
feet away from any equipment. Wipe all dirt and slime from the cap with a
Q-tip and swab it's whole surface with a seven percent iodine solution.
Pin the cap to the Table top by inserting three disecting needles at
equilateral points.
Sterilize an X-acto blade in a flame, let it cool for
a moment, then carve the outer skin of the mushroom. Cut out tiny pieces of
the inner mushroom flesh each the size of a match head. Spear each piece
with the blade point, raise the lid of the petri dish slightly, press the
tissue firmly into the agar surface, and close the lid immediately. Place
all dishes so inoculated on the incubation shelf at room temperature. The
mycelium must breath as it grows, so do not cap the lids too tightly.
When the radial growth of the mycelia appear on the agar surface (3-5 days)
these stock cultures are ready for transferring to the broth jars. If any
stock cultures are not going to be used immediately, tighten their lids and
place them under refrigeration. They can be kept this way for about a year.
RAISING CROP CULTURES OF MYCELIA
The task now is to select the most vigorous appearing mycelia in the dishes. This means the largest and fastest growing specimens and, of course, those not contaminated by foreign molds. Contaminants are not difficult to detect because their appearance differs greatly from that of the mycelia. Mycelia are pure white fibrous mats sometimes having a light bluish tinge.
Contaminants may appear as rapid-growing, tiny, white circular spots with
blue-green centers, or as surface scums or fuzzy clusters of either gray,
black, yellow, green, or blue color. If any contamients appear in any of
the culture dishes, discard those cultures. When the dishes containing
the choicest mycelia have been selected the mycelia can be transferred from
the agar-based stock cultures to the liquid broth cultivation jars. These
jars should have been prepared and sterilized three days before transferring
and allowed to stand at room temperature during this time to test the
effectivness of sterilization by observing if contaminates appear. Discard all
broths which contain growths. The uncontaminated jars are now ready for
inoculation. Spray the room and clean the work area as described under
pure culture techniques. Also spray the outside parts of the stock dishes
and culture jars. Lift the lid of a stock dish just enough and pick up a
fragment of mycelium with an inoculation loop that has been flame sterilized
and allowed a moment to cool. Lift the cover of the jar, place the
mycelium fragment in the broth and cover the jar immediately. Repeat this
until all jars have been inoculated. Refrigerate all unused stock cultures.
Tighten the jar covers and shake well to disperse the inoculum throughout
the broth. This also aerates the medium; the mycelium needs oxygen for life
support and growth. Loosen the lids again and place the jars on the growing
shelf for 10-12 days at 70-75 degrees F. If other species than Psilocybe
cubensis are used, adjust the temperature accordingly. Every 2-3 days
tighten the jar covers, shake to aerate and disperse mycelium, reloosen the
covers, and return the jars to the shelf.
The process of growth can be followed with a saccharimeter. The maximum growth and highest percentage of psilocybin occurs about four days after all of the broth's sugar content has been used up. The mycelium should be harvested at this time. Any jars that cannot be harvested on that day should be refrigerated until this can be done.
HARVESTING AND DRYING
Filter the medium of each jar through a clean flannel cloth, collect the mycelial material from the cloth, and place it in a pyrex baking dish. Do the same with each jar of mycelium until each baking dish is about 1/3 full with mycelia. Dry these in an oven at no higher temperature than 200 deg F. Use an oven thermometer. Do not rely upon the temperature indications on the oven knob as these may vary from accuracy. Check the baking dishes periodically. When the material first appears to have dried shut off the heat and let the dishes stay in the oven until it has cooled. This ensures the evaporation of residual moisture. Each cultivation jar should yield 50-100 grams of wet mycelium. Fresh mycelium contains about 90 percent water, so this much would dry down to 5 to 10 grams of crumbly material. Each baking dish would contain a dozen or more mycelia.EXTRACTION
Crumble and pulverize the dried mycelial material and combine each 100 mg of this material with 10 ml of methanol. Place the flask in a hot water bath for four hours. Filter the liquids with suction through a filter paper in a buchner funnel with Celite to prevent clogging. Collect and save the filtrate liquids. Heat the slurry (the mush in the filter paper) two more times in methanol as before, filter, and accumulate the liquids of the three extractions. To be certain that all of the alkaloids have been extracted do a small extraction with a portion of the used slurry and test with Keller's reagent (glacial acetic acid, ferrous chloride, and concentrated sulfuric acid). If there is a violet indication, alkaloids are still present and further extraction is in order.In an open beaker evaporate the liquids to total dryness with a hot water bath or by applying a hair dryer. Be certain that all traces of methanol have been removed. The remaining residue should contain 25-50 percent psilocybin/psilocin mixture. Greater purification can be achieved, but would require other solvents and chromatography equipment and is hardly necessary.
Each 100 grams of dried mycelium should yield about 2 grams of extracted material. This should contain at least 500 mg of psilocybin/psilocin mixed or about fifty 10 mg doses. Theoretically psilocin should have the same effect upon the user as psilocybin. The only difference between the two is that the later has a phosphate bond which disappears immediately after assimilation in the body. In other words, in the body psilocybin turns into psilocin. Psilocybin is a fairly stable compound, but psilocin is very susceptible to oxidization. It is best to keep the extracted material in a dry air tight container under refrigeration. A sack of silica-gel can be placed in the container to capture any moisture that may enter.
DOSAGE
The standard dose of psilocybin or psilocin for a 150 lb person is a 6-20 mg dose. We will figure the average dose as 10 mg. The crude alkaloid extraction process given here yields a brownish crystalline powder that is at least 25 percent pure. Each mason jar should contain at least 50 grams of wet mycelium. After drying this would be about 5 grams of material. The crude material extracted from this should contain 25-30 mg of psilocybin/ psilocin or roughly 2-3 hits. This yield may very to some extent depending upon several factors. Many of these species contain less of these alkaloids than dose Psilocybe cubensis and the alkaloidal content of this species may very in different strains. Cultivation conditions have alot to do with yield too. Higher temperatures (75 degrees F.) cause more rapid growth but lesser psilocybin content than do lower temperatures (70 degrees F.) One must test each new batch of extracted material to determine the proper distribution of dosages. Depending on the potency of the mycelia and how well the extraction was conducted the dose may range between 25 and 100 mg. Also bear in mind that the dose varies for different individuals.LARGE SCALE PRODUCTION
The techniques and procedures described in this guide can be employed to cultivate modest supplies of psilocybin for personal use, or they can be expanded to apply to the large scale production of many thousand doses per week. A small 10 x 15 foot room with standard 8 foot ceilings can be set up to produce an unending yield of at least 5000 doses per week. The stock culture shelves here are 1 foot deep and 5 feet long. Each could hold twenty 15 cm petri dishes. If shelving is spaced six inches apart, there can be as many as 16 shelves stacked in this space. This would allow for up to 300 stock culture dishes going at one time. The crop culture shelves can be stacked ten inches apart, accommodating one quart size mason jars and giving ten levels. With the dimensions of the room as mentioned this much shelving could hold about 2800 jars (3 deep and 3 per running foot). The entire room - walls, ceiling, and shelving - should be painted with a white, glossy kitchen enamel. This is not only an important sanitary measure, but also improves the efficiency and even distribution of light in the room.Lighting should be provide by a few banks of wide spectrum fluorescent tubes fairly evenly distributed across the ceiling and turned on for 10-12 hours regularly each day. These are great dust catchers, however, and must be wiped clean periodically. The work table should also be painted with a hard smooth, white finish. If the table is metal, a small, clean cutting board must be provided on which to pin down mushroom caps when disecting them. Shelf boards on the wall next to the table may be extended above the table to provide space for storage of work equipment and ready containers. A hood should be constructed around the table to protect it from dust, etc. A fume hood with a flu vent and spark-free exhaust fan should be constructed over the extraction area to remove toxic and combustible methanol vapors.
Extraction is preferably conducted in another room. If the cultivation room is used for extraction while the cultures are growing, care must be taken that the heat from the extraction process does not alter the room temper- ature. The fume hood will help by carrying off most of the heat. A vinyl shower curtain should be hung around the work table to shield the area of breezes when anyone enters or exits the room. Another vinyl curtain can be hung just inside the entrance to serve as a dust trap. A person entering the room would close the door behind him before pulling the curtain aside - and vice versa on exiting. The floor should be white vinyl or asphalt tile or painted white and coated with verathane or polyurethane. There should be no cloth or carpeting in the room except for a supply of clean worl clothing and surgical masks. The only other items in the room would be a stool at the work table, a three step ladder for reaching the upper shelves, and a small table on rollers on which to place jars and dishes when making the rounds of the shelves.
Unless one has a large staff of assistants it would be impossible to inoculate 2800 jars in one work session. After getting used to the work one could do about 100 jars an hour. The best procedure is to set up a continuous rotation of inoculations. Working about three hours a day about 235 jars could be inoculated each session. All 2800 jars could be inoculated in 12 days. Sections of shelving would be divided into groups of 235 jars, and these sections would be labled with the date and approximate time of inoculation. The work schedule for cultivation would be as follows:
| DAY | INOCULATE | SHAKE | HARVEST | REINOCULATE |
|---|---|---|---|---|
| Mon | Group A | |||
| Tue | Group B | |||
| Wed | Group C | Group A | ||

MAINTAINING A PERPETUAL PSILOCYBIN FARM
Fresh inoculum can come from stock culture dishes kept under refrigeration. If these should become depleted, healthy strains of mycelium from the crop cultures can be used to inoculate sterilized agar media in dishes. To do so shake the crop culture jar violently to break up the mycelium. Then transfer drops of the liquid into autoclaved petri dishes of unused agar medium with a sterilized pipette and let it grow as before. If this reinoculation of stock cultures from existing crops is continued over a long period of time, the strain will eventually weaken due to what is known as the senescence factor. To avoid this alternate the media used in the stock dishes. That is: if PDA is used the first time, use MEA the second time and PDA again the next time, etc.RECOMMENDED READING
