Candelaria pacifica is a yellow-green to bright yellow foliose lichen species that grows on trees, shrubs, and rocks. In East and Central Texas, it is commonly found on oak, elm, and cedar trees, as well as on fences and other man-made structures. The lichen has lobes that are 1-5 mm wide and a cortex that contains usnic acid, resulting in its bright yellow color. It thrives in areas with full sun to partial shade and moderate to high humidity, making it a frequent occurrence in the region's urban and rural landscapes.
