The lichen and its host tree are showcased in a photograph from Washington-on-the-Brazos State Historic Site in Washington, Texas. The common button lichen (Buellia stillingiana), distinguished by its black coloration, grows alongside Lecanora on a hackberry tree.
The image reveals the intricate details of the lichens and their host tree. Buellia stillingiana is characterized by its small, circular shape, while Lecanora forms larger, more irregular patches. The lichens are attached to the bark of the hackberry tree, which exhibits a rough texture with visible cracks.
The photograph provides an excellent example of how lichens can grow on various surfaces, including trees, and highlights their unique characteristics and habitats. – AI vision
