Well I for one WELCOME our new Fungal Overlords! ;)
That is an interesting one. Customers were always bringing in this or that ‘weird fungal issue’ to the Garden Center, and were always freaking out about mushrooms in their lawn.
Just disturb it - rake it out and it’ll die. No need for chemicals or anything. Conditions need to be warm and wet for fungus to grow.
Unless it’s taking over the countryside and/or trying to get into your house through a window or door, you should be OK. ;)
P.S. Do not eat it! :)
