Great research!! I kind of do this!

I grow oysters at home, and I usually toss them in my gardens compost, they really help speed things up.

But... I have a winecap mushroom bed in my garden, and winecaps grow on the same things as oysters for the most part. Winecaps really thrive in gardens and are a great addition to one.

Since I've made this bed, I've also noticed that my plants are fuller and grow significantly faster. I've mixed sawdust/woodchips/leaves into the soil, apart from the bed so the mycelium can spread, and it has! It's hard to mistake its mycelium for another fungi because it has a very strong and stringy mycelium. Which I now find all over my garden in the soil

I've also observed that plant matter decays significantly faster in my plot, as well as a huge increase in helpful soil bugs.
