Album 2438: Bryan, Texas, January 27, 2019

The image depicts a close-up view of various types of lichens growing on the lower branches of an old acacia tree (huisache) located between Signature Park 11 apartments and Oil Well near Park Hudson Trail in Bryan, Texas.

**Lichen Types:**

* **Hyperphyscia syncolla:** This species is characterized by its greenish-gray or brownish-green thallus with a smooth to waxy surface. The lobes are rounded and irregularly shaped, giving the lichen a somewhat lobed appearance.
* **Physcia lichens:** These lichens have a grayish-brown to dark brown thallus with a rougher texture than Hyperphyscia syncolla. The lobes are more elongated and pointed, resulting in a more linear shape.

**Growth Pattern:**

Both lichen species appear to be growing on the bark of the acacia tree, adhering closely to its surface. The lichens are densely packed, covering much of the exposed area between the branches. Some areas display only one or the other type, while others show both types growing together.

**Environmental Context:**

The image was taken in early January 2019, suggesting that the lichens have adapted to thrive under the specific conditions prevailing during this time of year in Bryan, Texas. The presence of these species implies a relatively stable and humid environment with sufficient sunlight for photosynthesis.

**Conclusion:**

In summary, the image showcases two distinct types of lichens - Hyperphyscia syncolla and Physcia lichen - thriving on an old acacia tree in Bryan, Texas. Their unique growth patterns and adaptations to local environmental conditions highlight the fascinating diversity of these organisms within their ecological niche. – AI vision
