Has anyone any experience of these. I have several about 5 feet
diameter and they produce a ring of small funghi which appears from
time to time (like now). The ring eventually kills the grass but
with a surrounding ring of very fertile grass. Underneath the dead
stuff is a lattice of white threads. How to get rid of? How did
it come in the first place? Why fairy ring? Why circular? etc?

Any useful comments welcome.
