**Lichen Details**
* **Parmotrema Lichen**: The first lichen is greenish-yellow and has a wavy, irregular shape with ridges that resemble small waves. Its surface is rough to touch.
* **Pyxine Lichen**: The second lichen is pale-green and grows in a more compact, rounded form. It also features a slightly wavy texture.
**Background**
The bridge's iron surface provides a reddish-brown background for the lichens, which are growing directly on it.
**Overall Impression**
The image suggests that the lichens have been growing on the bridge for some time and have adapted to the metal substrate. The diversity of these organisms in this environment highlights their ability to thrive in unexpected places. – AI vision
