Why 'Race', 'Variety 'and 'Subvariety' are Often More Accurate Terms Than 'Strain':
When discussing different types of cubes in general, let's use the words 'Race' or 'Variety' instead of the word 'Strain'. Cubes, like humans, come from all over the world... and like humans, there can be some variety from one cube patch to another. It is time for some racial tension here in the world of cubes. Most cubes are named after the place where their original wild spore specimen was discovered... so Race is a logical (if imperfect) word to use when describing these different types of cubes. At the very least, it is more accurate and far less confusing than the word 'Strain'.
In this thread, the word 'Strain' in quotation marks means something different than the word Strain without quotation marks. The word Strain refers to living dikaryotic mycelial tissue, the word 'Strain' refers to commercial spores.
The fungus known as Psilocibe Cubensis is a unique mushroom SPECIES. Shiitake is a unique mushroom species. Azures are their own species. Amanitas are a species... etc. It would be almost impossible and incredibly expensive to use two different fungus species and create a hybrid of the two. It'd be like successfully mating a human with a gorilla. However, a Caucasian human can effectively mate with an Asian human. Similarly, spores from one cube race can mate (or be mated) successfully with the spores of other cubensis races.
In the world of mycology, every single time a single spore's mycelium mates with another's to become dikaryotic, a unique Strain (no quotation marks) is created. Like baby humans, living cube Strains are each unique, and they tend to resemble their 'parents'. Each single viable spore print can produce thousands if not millions of unique strains. Most of these strains will produce mushrooms that look remarkably like the mushroom that produced the print from which they came.
The term 'Strain' is often used to describe the type of spores on a spore print or in a syringe filled with spores. When used in this context, the word 'Strain' is simply NOT ACCURATE (hence the 'Quotation marks'). It is a word used by vendors (who cater to hippies) in order to make magic shroom spores sound like different strains of marijuana. It is a word that suggests cubes are more varied from 'Strain' to 'Strain' than they actually are.
Marijuana is a plant, cubes are a fungus. Cubes come from SPORES, marijuana comes from SEEDS. Cubes breathe OXYGEN and produce CO2 as a byproduct (like animals). Marijuana, like all plants, breathes CO2 and produces OXYGEN.
The misuse of the word 'Strain' is widespread, and only encourages vendors to sell as many different 'Strains' as possible in spite of their obvious similarities. When people talk of commercial cube 'Strains' this leads to confusion and misinformation. Vendors (especially the shady ones) thrive on this misinformation.
An African, an Asian and a Caucasian are all undeniably human but there are obvious differences between each race. Even on a smaller scale... every single town (and sometimes neighborhood) in Great Britain features a slightly different dialect... and yet, there is still room for great diversity from one person to another in said towns... even though, when compared to a different race, most Brits tend to look alike.
Still, the world of genetics is often a funny thing, and sometimes spores will produce some surprisingly unique and unexpected strains... strains displaying recessive genetic traits and mutations that nobody could predict... again, just like humans.
These unique cubes can be selectively bred until these unique traits become common, even via multispore inoculation. This new, unique cube may be marketed as a new 'Strain' but it is really just a unique 'Variety' of cubensis spawned from its original race. Still, many vendors market each unique variety as a new 'Strain'. In general, every single commercially available cubensis 'RACE', is actually a domesticated VARIETY of the original specimen. Domesticated cubes contain intentionally limited genetics in order to increase the likelyhood of achieving the desired results, sort of like dog domestication and subsequent breeding.
Over time and multiple generations (spore to fruit to spore) a cubensis Variety can become genetically limited by inbreeding. This means results from multispore inoculation can become more consistent, and the likelihood of accidentally stumbling upon unique traits reduces. If a commercial cube's genetics become too limited, the inbreeding can produce undesired effects. In general, when it comes to life, too much inbreeding will eventually lead to problems.
Annother classification for different types of cubes is the 'Sub-variety'. For example, by using spores from each variety of cube, Workman crossed PF Albino (Probably a variety of the Matias Romero race) with Penis Envy (Probably a variety of an Amazonian or Columbian race) and produced the Albino Penis Envy. Albino Penis Envy is both a sub-variety of PF Albino and Penis Envy.
Since all this 'Variety' and 'Sub-Variety' talk can get very confusing, go ahead and use 'Race' if you prefer, even though it is not entirely accurate. It sure beats saying 'Strain'. There are racial differences between mushrooms, often due to natural selection based upon where they first grew... and sometimes varietal differences due to unnatural selection performed by mycologists.
Finally, there are different 'Brands' of cubes. A Sporeworks Brand syringe full of Penis Envy spores may have a slightly different ethnic diversity than a Ralphster Brand or Hawk's Eye Brand syringe of the same cube.
All of that said, vendors use the term 'Strain'... and n00bs learn the term from vendors. This incorrect term is SO widespread, it is even used in the same way by Paul Stamets. I'd love to use the proper terminology, and will do so from now on... but this will be an uphill battle. Most people recognize the incorrect term, and not the correct ones.
It seems the misuse of the word 'Strain' is only widespread in the world of magic mushrooms, but not in the rest of the mycological world. The fact that so many magic mycologists use incorrect terminology, further reduces our credibility in larger mycological circles. The misuse of this simple word can make our work seem illegitimate in the eyes of science.
