Armilleria Fungus - Root Rot - Honey Mushrooms - my dead trees

Just today I am reading about Armilleria and Honey Mushrooms. It is like reading a science fiction horror story. Supposedly, if I am not hallucinating, the fungus kills trees, has rhizomorphs that grow through the soil in search of more roots / trees to attack, and it can not be killed. See diagram attached below from the Forest Pathology article.


I lost my giant Red Oak in the back yard - see photo. It had what looked like honey mushrooms growing on it and after slowly realizing it was severely diseased and cutting it down, I learned the inside was rotten and smelled terrible - photo shows extent. The stump was ground down and covered with soil, but the mushrooms now appear in my lawn as far away as four feet from where the stump is located.


I had to cut down five trees in the front yard - all had a bit of fungus looking decay in at least one small area, even one of the big, healthy looking Bald Cypress trees that had to come down. I want to plant new trees in front, and I have one small Red Oak in back and two Magnolias. So I am wondering if my lawn is infected with Armilleria. The mushrooms on my tree / in my yard looked exactly like the two photos attached that I copied from the Internet. If my lawn is infected, is there nothing I can do to keep it from spreading? I think not. But maybe it grows and destroys roots so slowly that I shouldn't worry about the new trees. Any insight, personal experience, or opinion will be greatly appreciated.


Like I said, science fiction horror story, but here it is.
