Without a photo, it is hard to say, but I will give this my best shot.

It probably is yellow lichen - in which case it is harmless. Here is an example of what yellow lichen looks like:

Here is an article on tree lichen for more information: https://www.gardeningknowhow.com/ornamental/fungus-lichen/treatment-tree-lichen.htm

If it's not lichen, then it's going to be either a fungus or a mold but it would be difficult to propose a treatment without a photo for identification.
