Q.Do You Recognise The Attached Photo Of A Fungus In My Garden And How Can I Get Rid Of It.
The fungus has spread in clumps over a space of about 6 sq ft and the earth underneath is extremely dry. I have dug it out but it keeps coming back.

It's a type of mushroom. To eliminate them, make your soil less hospitable. They like shady, moist areas with decaying matter such as leaves, sticks, etc. I'm surprised it thrives in your dry environment.
