I have a mature meyer lemon tree that has a few different types of fungus on the branches and the base of the tree. The leaves and the fruit look great. I've attached a picture. I'm wondering what I should use to get rid of it.
Fungus on lemon tree

I see some tree lichen on it. They don't necessarily require removal. Maybe try a post in the plant id forum here and someone can id them specifically.
