Sounds like it's the agar. Just because it grew bacteria from your mouth doesn't necessarily mean it has the proper nutrition to grow mycelium. There's some nasty dank ass bacteria in the human mouth which I'm sure can grow on next to nothing .
Here's another test if you have a PC. Put a fully colonized grain on it and see if it shows any growth.
Spores are also a great on agar. They take a while to germinate but it's a good way to get multiple isolates and test which ones yield well and have high potency. You can just scrape them from a print or put a drop from a syringe.

The LC is a good idea too. If any type of live mycelium doesn't grow on it then it's gotta be the agar.

If it's a tiny, tiny piece of tissue on a hot blade, you could be frying it. Try a larger piece, dunked in peroxide, from the stipe of a young specimen.
Even with no nutrients, you should still see some growth from the tissue on agar, even if it's just a tiny amount as it's searching for better living conditions. The only way you could have zero growth is from dead tissue.

Do you know what is in the agar? When you say premixed, what is the mix or the use? Maybe there is nutrients lacking or monosaccharides or starch.
Maybe it is better to just treat it like pure agar and add the rest yourself. At the risk of being redundant, that would at least exclude the constitution of the agar being the problem.
If you tried this repeatedly it seems doubtful that you used mushroom tissue that is not viable, if even dried mushrooms can even be viable!
So little else remains as possible reasons. Right?
