(Question)
Hi, we have a flat white spreading fungus that is growing on the ground in our garden around plants and at the base of two trees. What is it ? What can we do? We are in the High Park area.

Fungi grow on decomposing woody materials in the soil . This is a natural occurrence in nature, especially if the area is damp. It looks as if you might have a soaker hose next to the tree providing the fungi with the moisture it needs.
I have attached links to two interesting web sites which will provide you with further information.

If you remove the soaker hose and let the area dry out the fungus will dry up.
