Deutero fungus (Neocercosporidium smilacis, Cercospora ...

The image shows a close-up view of multiple leaves from a plant known as the common greenbrier (Smilax rotundifolia), which is native to eastern North America and parts of Texas.

The leaves are light green with large brown spots that have red centers, while some smaller leaves appear healthy. The leaves are irregularly shaped, being longer than they are wide.

There appears to be a fine web on the stems, but it is not clear what this is, as it could simply be part of the plant's anatomy. The background is obscured by more leaves and branches.

The image may have been taken to show fungal growth on the greenbrier leaves, although no evidence is visible in the picture.
