Ethnomycology

Ethnomycology is the study of the historical uses and sociological impact of fungi (a.k.a. "fungi lore"), and can be considered a subfield of ethnobotany or ethnobiology. Although in theory the term includes fungi used for such purposes as tinder, medicine and food (including yeast), it is often used in the context of the study of psychoactive mushrooms such as psilocybin-containing mushrooms, Ergot and Amanita muscaria. By analogy to the term entheogen the term "entheomycology" (ἔνθεος entheos meaning literally "god within", more freely translated "inspired") has been suggested for the study of psychoactive mushrooms used for spiritual purposes.

The amateur researcher Robert Gordon Wasson rekindled interest in this field of study in the late 1920s, inspiring later (sometimes non-academic) researchers such as Terence McKenna, Carl Ruck, Giorgio Samorini, Keewaydinoquay Peschel, Richard Evans Schultes, John Allegro, Clark Heinrich, Dan Merkur, and James Arthur.

Besides mycological determination in the field ethnomycology depends to a large extent on anthropology and philology. One of the major debates among ethnomycologists is Wasson's theory that the Soma mentioned in the Rigveda of the Indo-Aryans was the Amanita muscaria mushroom. Following his example similar attempts have been made to identify psychoactive mushroom usage in many other (mostly) ancient cultures, with varying degrees of crediblity. Another much written about topic is the content of the Kykeon, the sacrament used during the Eleusinian mysteries in ancient Greece between approximately 1500 BCE and 396 CE. Although not an ethnomycologist as such, philologist John Allegro has made an important contribution suggesting, in a book controversial enough to have his academic career destroyed, that Amanita muscaria was not only consumed as a sacrament but was the main focus of worship in the more esoteric sects of Sumerian religion, Judaism and early Christianity. Clark Heinrich claims that Amanita muscaria use in Europe was not completely wiped out by orthodox Christianity but continued to be used (either consumed or merely symbolically) by individuals and small groups such as medieval Holy Grail myth makers, alchemists and Renaissance artists.

While Wasson views historical mushroom use primarily as a facilitator for the shamanic or spiritual experiences core to these rites and traditions, McKenna takes this further, positing that the ingestion of psilocybin was perhaps primary in the formation of language and culture and identifying psychedelic mushrooms as the original "Tree of Knowledge". There is indeed some research supporting the theory that psilocybin ingestion temporarily increases neurochemical activity in the language centers of the brain and, though this is hardly enough to substantiate McKenna's ambitious claim, it does indicate a need for more research into the uses of psychoactive plants and fungi in human history.

The 1990s saw a surge in the recreational use of psilocybin mushrooms (a.k.a. "shrooms") due to a combination of a psychedelic revival in the rave culture, improved and simplified cultivation techniques, and the distribution of both the mushrooms themselves and information about them via the internet. This "mushrooming of mushroom use" has also caused an increased popularization of ethnomycology itself as there are many websites and internet forums where mushroom references in Christmas and fairy tale symbolism are discussed. It remains open to interpretation what effect this popularization has on ethnomycology in the academic world, where the lack of verifiable evidence has kept its theories with their often far-reaching implications shrouded in controversy.
