Well Being I heard from the big boys that are my mentors I guess that mixing t3 and pr's have a very slim chance(but not impossible) of picking the fruit of the hybrid...I will not play with this experiment and now will focus on the 4 different Pan strains from around the world I have obtained...Thanks Anno and Teonan!!! I am sorry to force my hybrid theory on anyone but What the hell do I call the 3rd gen cube I have in the future...Nice rhizo myc but switches to fruit rather easily...with nice large fruits that are potent...I just will keep these spores to myself here on out and call them my strain. That way it doesnt pollute the true spores floating out there 'just in case the genetics did mix....Thank you to all the knowledge givers but not the hate throwers........

You are absolutely right. Without a verifiable, reproducable, study, DOCUMENTED with pictures and DNA proof, this is all an educated assumption. There is more proof to support that this will occur then that it won't!!!!
I certainly don't think injecting spores of two strains into a jar of substrate is proof that it won't. I certainly don't think casing a tray with two different strains spawn is proof that it won't happen. Actually plating out monokaryons, mating them, and fruiting the resultant Dikaryons will be proof, verifiable by DNA for those that did not do the study. You still have to ASSUME when you view the study, that the scientist actually used the different STRAINS. They could just be lying. An assumtpion you would probably make when the evidence is presented to you. UNLESS YOU TRY IT, you will never be convinced. 
The information is being posted in case someone less skeptical/or even more skeptical then yourself, might decide to try it.

I saw some guys at the shroomery's having microscopes . They did pics of single spores... they are the ones to bring two different spores together on agar...
Also the easier method of crossing two diff. strains is xplained in Stamet's "Mushroom Cultivator"

Personally, I think penis envy is just such a 'hybrid'. Take a close look at it. . .

I know this is horrendous of me to do, but having come across this gem of a thread in the archives I thought I would give it a ressurection for the new generation of mycophiles who may have such questions..
Teonan laid it out here so well it should answer almost any questions regarding hybridizing strains.
So don't flame me for resurrecting an ancient post, I know its ancient but its good info that I think might interest alot of people.

i also realize this is an old thread, but i'll shed some light on a real way to cross "strains" (not species) that i learned from Workman over at mycotopia.
Get a single spore isolate of the first strain you want to cross and transfer an agar wedge to some grains, let it almost fully colonize.
then dilute some spore solution of a different strain. inject this solution into the colonized grain.
the idea is that since the colonized grain is only colonized by a single spore isolate's mycelium, then the diluted spores you inject have a better chance of joining with this isolated mycelium rather than with a spore of its own strain. you'd have to REALLY dilute the 2nd solution, i mean use 1 drop of normal spore solution to 10cc of plain water, and shake ALOT or use an ultra-sonic bath (jewelry cleaner type thing) to break up any clumping spores.
even if the 2nd strain does join with eachother, remember that MOST of the mycelium in the jar WILL be a cross.
why?
the jar was first fully colonized by monokaryotic mycelium, so once it starts to fruit, you know that at the VERY VERY least you'll get atleast one crossed fruit.
if you dont believe me check out Workman's PF-albino/Costa Rican cross and his PF-albino/Penis envy crosses over at mycotopia.

Maybe someone can clarify the nomenclature for me, but I thought that A1+B2 and A2+B1 would be compatible mating types not A1+B1 and A2+B2 as indicated way back in this post...
Also talk of DNA proof is just silly IMHO. That's never going to happen and nobody in the mycological field demands that level of proof. The standard for proof of mating is observing clamp connections. You take single spore isolates, plate them together and observe any clamp connections or the lack thereof. If that culture produces fruit and spores then you have a cross.
Also talk of hybrids is not exactly correct. Hybrids are between different species such as a mule is a horse-donkey hybrid. There are many more examples in the plant world, but hybrids are almost always sterile. Intra-species mating produces a cross, not a hybrid.
One other note... I think a lot of spore vendors are pulling a lot of bullshit when it comes to claiming new strains. From the discussions here I think that they are just mucking up the genetics and obscuring the true lineage of the products they are selling. This is definitely detrimental to the science of mycology, if not downright dishonest.
To explain... If you take single-spore isolates of two separate strains and mate them you will come up with a cross. You are absolutely guaranteed that this is a new genetic combination never before seen. If you then take the progeny of that cross and breed it normally with itself for several generations you will have a true-breeding strain that can honestly be called it's own strain.
If on the other hand you mix strains A and B in a syringe or in a substrate... You have just lost the genetic identity of any progeny or future offspring of that mixture. You don't know if the spores you collect from the fruit are strain A, strain B, or an AxB cross! You have just lost any idea of it's true lineage. And there's no way to recover that information! You will never know who the parents are and it will forever be a bastard culture. All this does is muck around in the dark with the gene pool and create bunches of "new" "strains" that might not even really be crosses at all.
So if you don't have the equipment or know-how to do controlled mating experiments, please do them only for your own enjoyment and know that they will be always be bastards of unknown parentage. It's not hard to do it right. Even the cheapest kids microscope can spot individual spores. Simply dilute your spores enough so that you can pick them individually off of your agar (preferably before they even germinate). Always check them with a scope! Spores love to clump. Germinate individual spores on separate media, labeling what strain they came from, and mate them to your heart's content. It's that easy! All it takes is a $15 microscope and $15 worth of agar... That's not too much to ask of people that want to claim new strains is it?

I keep hearing the same claim that crossed strains are not really hybrids. Has anyone actually looked up the definition of a hybrid? It is not as restrictive as some people seem to think.
hy·brid (hī'brĭd)
n.
Genetics. The offspring of genetically dissimilar parents or stock, especially the offspring produced by breeding plants or animals of different varieties, species, or races.
I recently bought some hybrid tomato and corn seed and I don't think they were crossed with other species. Crossing two different varieties of cubensis is considered a hybrid under the above definition.
Most strains of cubensis are very similar in appearance making visual confirmation of a successful cross impossible. For this reason I have been using very distinct strains, such as the PF Albino and Penis Envy, as my parent stock.

I stand corrected. I would say though that hybrid implies more genetic dissimilarity than the term "cross". A cross is pretty generic in that you can apply it to almost any mating. I would say it only implies that it's not selfed. The term hybrid definitely means genetic dissimilarity though. There's quite a few "strains" that don't show enough variation to qualify as hybrids when crossed IMHO.
Nice link, looks like you did some good work. If you have a distinct phenotype like albinism you don't really need to use single spore isolates to prove a cross. I wasn't thinking along those lines since it doesn't really apply to vary many strains. As long as you can show some sort of Mendelian breakdown of distinct traits in the progeny you don't need to spend the time doing spore isolates. Nice work Workman.

i totally agree. i cross pollinate christmas cacti (pink and red) and they are considered hybrids. same with flowers, you hybridize flowers for a specific color or some other phenotype.

Workman's Hybridization Experiments
Interesting. So you consider a child born to a woman from france and a man from china a hybrid? I prefer the term 'interracial', but that's just me.
In my opinion, a 'hybrid' should be a bit more difficult to acheive than that. It's relatively easy to cross various strains of cubensis, with or without monokaryons, so I fail to see any real acheivement in doing so.
Species of fungi have been successfully crossed, so in my opinion, that ups the ante in what we/I call a hybrid. As I've said previously, others are free to disagree.
Personally however, I will not to claim any work I do as a hybrid until it's a cross species pairing.

so if you could cross a cat and a dog then and only then would you consider it hybridizing???
so dogs such as a yellow lab and a chihuahua mate it's not a hybrid because it's still in the same species???

Technically, a French-Chinese child would be a hybrid by the definition posted, even if the term is considered distasteful when a applied to humans. Interracial is merely the politically correct term and I have never seen it commonly used for anything other than people of mixed ancestry.
It would be helpful to amend the hybrid designation with the level of hybridization. Such as varietal hybrid, interspecific hybrid, intergeneric hybrid, etc.

An interesting aspect on the "interracial hybrid", some studies were done on schools in Papua New Guinea. Turns out that the schools there were filled with a disproportionate amount of "hybrid" children(ie from mixed white and local parents). Supposedly they exhibit a degree of hybrid vigor - out performing both white/local children on average in many tests.
Quite cool

A1B1 monokaryons can mate with A2B2
A1B2 can mate with A2B1.
They just have to be different A and B factors.
A1B1 can also mate with A3B3, etc...............
