I haven't used mycorrhizae either, at least not specifically. I have used potting mix with it in, like ProMix BX. I believe certain genus requires specific type of fungus.

My homegrown compost is teeming with obvious, apparent fungi and mold, and that eventually ends up in my garden beds and/or flower pots. That's my only experience with fungi.
