🎞️ #3134-17

The image presents a microscopic view of the aecial peridium of Puccinia dioicae, a rust fungus. This particular sample was collected from cut-leaved evening primrose in Lick Creek Park, College Station, Texas, on April 18, 2022.

Upon examining the image closely, several key features become apparent:

* **Coloration:** The aecial peridium exhibits a striking yellow coloration, which is characteristic of Puccinia dioicae.
* **Shape and Size:** The structures appear to be spherical or oval in shape, with varying sizes. This suggests that they are likely immature spores or urediniospores.
