"sub-strain"

I need some clarification on a couple things. I looked the information up and was able to obtain bits and pieces (through reading people argue) that I need to put together.
Is the word sub-strain even a word? Wouldn't it be more like a "child" of that particular strain...which exhibits certain genetic traits due to monokaryotic(single nucleus)pairing?
When I isolate mycellium, am I isolating hyphae that have already combined? And is the mycellium itself nothing more than thousands of "ropes" of combined hyphae? If this is so...then what matter is the actual fruit body made up of, and where does it get its traits from? One "dikaryon" in that tangled mess of paired hyphae?

Yes. Unless you're using a microscope to isolate hyphae. When a spore germinates it forms a strand of hyphae. When two strands of hyphae join together it's called mycelium. When you do your first isolation and extract a tiny bit of mycelium there will be many "strains" all jumbled together. By transferring a small piece of mycelium you're reducing the overall amount of strains compared to the original MS culture. As you do this a few times you'll narrow it down to just one strain.
A strain is formed whenever two spores germinate and join into mycelium. A drop of MS solution could produce countless different genetic strains.

A fruiting body is essentially mycelium that has formed into a mass. Fungi are totipotent, meaning you can form a fruiting body from mycelium or you can form mycelium from a fruiting body.

SO by fruiting an isolate, the resulting fruit body will (should) be the phenotype of one strand/strain (infinitely branched of course) of mycellium (combined hyphae).
Also the fruit body itself doesn't really resemble ropey web like mycellium. How can it go from being one texture to another? What is happening?
And with a multispore grow...is one strain (strand of mycellium) going to determine the phenotype of a certain fruit, or do other strains have a factor in the phenotype of that fruit. See what Im sayin?

Clones from a single fruit often result in sectoring so many genetic strains must be present.

Sort of.
There often will be many millions of germinated spores and therefore many thousands of dikaryotic pairings when a sporeprint is used. Each of these pairings is by definition a strain. Many of these strains will be compatible and will experience dikaryotic/dikaryotic pairings, while others will remain separate. The mycologists' job is to fruit out each one to find the stellar performer(s). RR

And the phenotype/genetics of the fruit come from? And the composition of the fruit body is made up of what exactly? It doesn't seem to resemble mycellium...more like some soft rubber.

It is tightly bound mycelium, nothing more.

This indicates bacteria contamination. RR

Im referring to the over all texture of the fruit body. Is it straight mycellium, and why does it appear different in general... different then colonizing mycellium. Is it swollen or something?

The filamentous (thread-like) cells of a fungus are referred to as hyphae. When hyphae bundle together and grow to form a vegetative structure (the fluffy white threads that grow over a substrate) they are referred to as mycelium. The mycelium will aggregate and differentiate to form a fruit body (the mushroom). It's the same hyphae that make up both mycelium and mushroom, but exhibiting different forms of growth. Just as the cells of your body differentiated to grow into different organs.
