Psilocybe mexicana A is the mushroom species that Dr. Albert Hofmann made world famous in 1958 when he was the first to isolate two chemicals from this fungus. These chemicals are now known as psilocin and psilocybin. P. mexicana A is known to produce sclerotia in a high quantity in the optimal circumstances.
The mushrooms of the Psilocybe mexicanae have been used for thousands of years by the natives of central America and there is some evidence the these are the “Teonanácatl” that they have discribed in their traditions. Teonanácatl has been translated to “Flesh of the Gods”, a name familiar to most psychonauts.
Psilocybe mexicana A are available in a 15 grams vacuum packed quantity. Because of this package, the truffles can be kept for a longer time. Upon receipt of the package, store it in the refrigerator (2-8°C) right away. It can be stored this way until the best before date as written on the package.
A sclerotium is a living product. It might be possible that air (especially CO²) might be trapped in the package. This will make the sclerotia continue to grow and white “hairs” will appear on the outside of the truffles. This is the mycelium and shows the truffles are healthy. This is edible and doens’t affect the trip.
