🎞️ #2217-11

The image shows a close-up view of a prickly pear cactus on the Kiwanis Nature Trail in College Station, Texas. The photo was taken on December 20, 2017.

The main subject is an Opuntia (prickly pear) cactus pad that has been affected by a fungal disease known as Aspergillus alliaceus or Pad decay fungus. This pathogen causes the cactus to rot and discolor, resulting in dark gray to black lesions with tan to orange spots on its surface.

Other objects visible in the image include:

* The green stem of another prickly pear cactus pad
* Brown dried leaves from other plants

The background is out of focus but appears to be a mix of brown fallen leaves and possibly some dead plant material. – AI vision
