Lemon Lichen

Candelaria concolor


This bright yellow growth was on the trunk of a mahogany tree. It seems to be growing on top of the older light blue and whitish growths seen in last photo where a small spot of yellow is showing.


The trunk of a mahogany tree.


I see this growth on all sides of the tree and on some woody bushes elsewhere in my backyard as well. Perhaps some sort of lichen?
