For 3rd year in a row a spongy fungus is growing thru the bark on my maple tree. Is the tree dying?

Question

Fungus is like a sandy colored cauliflower consistency and it stretches about 2 feet. In the spring it drops off and comes back in the fall. Lanscaper said it means the tree is dying.

Fungi usually produce spores, these spores may be carried from plant to plant by wind, water, insects, and tools. Fungus spores require adequate moisture and the right air temperature to begin new infections. A plant/tree wound is sometimes also needed as an entry for the fungus. Many fungal diseases are common during wet, humid seasons.
For more accurate disease diagnosis, consult your county Extension agent.
