The image shows a close-up view of the base of a pine tree affected by gall rust (Endocronartium harknessii or Cronartium harknessii). The photo captures the underside of the pine's trunk, revealing large patches of orange-yellow fungal growth along with brown bark. This fungus is causing the tree to swell, as evidenced by its bulging appearance.

The base of the tree is covered in a thick layer of gall rust that has spread throughout the wood and formed large clumps. The rest of the bark remains intact, but some areas appear to be breaking off from the main trunk due to the swelling caused by the fungus.

This image was taken in Sam Houston National Forest's Little Lake Creek Wilderness on March 11th, 2023. The location is identified as being near Pole Creek on North Wilderness Trail within Montgomery, Texas. – AI vision
