This is one reason why I was so worried about Glysophate ("Roundup"). It attacks the mycelium -- you can see the result in the soil after a couple of years of use.

I once had a colleague who had worked on Glysophate earlier in his career. He was really proud of his work because "you can drink it, and it breaks down harmlessly in the soil". He never worried about the fungi.

Edit: moronic brain fart in writing rhizome rather than mycelium. Extra embarrassing as at the time described we were working on antifungal drugs.
