What Is This White Fungus?

Question

Pine cones and twigs that have been buried with compost for a year or so are often covered with a bright white fungus when I dig my raised bed. The contamination seems to be spreading. Any idea what this is? Is it dangerous? What can I do about it?

Answer 1

That's actually what is breaking down those things in the soil. It is fairly important to make sure that it is broken down pretty well before planting, or it will leach nutrients from your plants.

The white mycelium that you see is fungal, but beneficial. Getting rid of that would leave your garden unusable for a short time.

Let the rest of that decompose, and turn the soil frequently, until most of the wood has broken down into soil.
