I've read online that you can compost perlite without a problem, and it actually has some benefits. I couldn't find information online that says that composting vermiculite is okay.
I know it is generally added to soil and has many benefits, but I want to know if composting is okay and if anything will happen to it during the decomposition time.
The reason I am asking is that I had a small mushroom growing on the bed of vermiculite. It has some mycelium in it, hence I wasn't sure if just putting it into the soil would be good. But also, I am just curious.
