A white growth about the size and shape of a 7year childs hand. I have it sealed in a poly bag and photos of it. Will it spread and is it dangerous in the garden.
I need to know of gthe dangers and whether any one would likwe it to study. Do I put it in the freezer to keep?
Whatever it is, it's unlikely to stand freezing if it's a fugus.
Do you have a friend who's a member of the RHS? They would identify it for you.
That sould have been "fungus", not "fugus"
