The image presents a close-up view of yellow leaves from frostweed (Verbesina virginica) infected with Coleosporium viguierae(?), a type of rust fungus.
* The leaves exhibit a bright yellow coloration, indicating that they are infected.
+ This is evident due to the presence of numerous small brown spots on their surface.
* The leaves display a large number of brown lesions or pustules, which release spores into the air.
+ These spores can be carried by wind and infect other plants.
The yellowing of the leaves is likely caused by the infection, as Coleosporium viguierae(? ) targets the plant's photosynthetic tissue. – AI vision
