Close-up of thin yellow crust of corticioid fungus Hypoxylon rubiginosum around tunnels of bark beetles on an elm log in wet area on Caney Creek Trail (Little Lake Creek Loop Trail) in Sam Houston National Forest north from Montgomery. Texas

🎞️ #3386-13

The image presents a detailed close-up of the Hypoxylon rubiginosum fungus growing on an elm log in a wet area of Caney Creek Trail within Sam Houston National Forest north from Montgomery, Texas.

In the center of the image, there is a large section of bark that has been removed to reveal the yellow crust of the fungus. This fungus appears to be corticioid, which is characterized by its thin and flat growth structure. The edges of the fungus are slightly raised and resemble tiny mushrooms or lichens growing along the edge of the log.

The bottom left portion of the image shows a small tunnel with a dark brown color, indicative of the presence of bark beetles. These insects are known to create tunnels in tree trunks as part of their life cycle.

The background of the image is primarily made up of the yellow crust of the fungus, which covers most of the visible surface area. The remaining sections consist of small holes and cracks in the bark where the fungus has broken through or grown around existing crevices.

Overall, this image provides a unique view into the intricate details of forest ecology by highlighting the relationship between fungi, insects, and tree trunks. – AI vision
