Orange-Colored Substance on Maple


Anonymous added on December 31, 2016 | Answered

What could an orange-colored substance be that I just discovered on an older maple tree? I have an older maple tree (not sure which kind), but recently noticed an orange-colored substance on the trunk of the tree which looks like orange sherbet. I have washed it off with a water hose. Did not take a picture, but it was yucky. I believe it was on there last year, but not sure. Very prevalent on the east/slightly north side of the tree. We have had a tremendous amount of rain the last few weeks in this area. Do you know what it might be and how to treat it? It is not like a canker, but smooth flowing at the trunk of the tree about 3 feet from the bottom.

This is likely a Jelly Fungus.
Here are some links with more information.
Many times it is completely harmless and grows due to wet conditions.
