This image presents a close-up view of Texas wintergrass fungus (Atkinsonella texensis) on Nassella leucotricha grass blades.

The fungal growths are dark gray to black and irregularly shaped. The infected areas of the grass appear yellowish-green, with the fungus growing at the base of each blade. Each affected area is approximately 1 cm in length, and they are separated by uninfected sections of grass.

In the background, the blades rest on a wooden surface that appears to be weathered gray wood or possibly an old picnic table.

The photograph was taken on May 22, 2022, at Washington-on-the-Brazos State Historic Site in Washington, Texas. – AI vision
