Maple tree fungi
I have maple trees about 4 years old. One has developed a fungus which is white in color and very hard to the touch. Almost impossible to remove without some sort of tool. What might it be and what can I do to rid of it? Thanks.

It is a toadstool. They do not pose any threat to your tree, but if you want to get rid of it, you can just treat it with a fungicide. This should take care of it.
