You have the makings of a fairy ring .......they are devouring my lawn
Remove every single toadstool and put in dustbin not compost
You may need in the end to take drastic measures like digging up the entire
top 14 inches of soil and lawn and removing it

Eh? Why? That is complete insanity. "Brian" is quite right.

some idiot has left tree roots/stupms to rot underground and its that which
is feeding the fungi

The fungi which make fairy rings are not the same ones that feed on
rotting wood!

Yes, and neither are (normally) harmful. A very few of the "fairy
ring" fungi will harm lawns, but the vast majority should be treated
as "Brian" says.

The vast majority of fungi are harmless in a garden, and some are
beneficial. Also, most of the harmful fungi do not produce large
fruiting bodies (toadstools).
