Shrooms

[Bduck]

I have been trying to rid my yard of these massive white mushrooms. I've had small ones over the years which is no big deal, but these big ones are overcoming. Walking in the yard I can feel a big lump forming and about to break surface, I would dig them out. Wondering if mulching leaves from my trees every fall could be playing a part in the fungus among us. I've always seen big shrooms out in the forest floor. The past 3 maybe 4yrs is when I noticed I was growing big shrooms with this year really bad. I get a daily bag of them digging them out.
