Album 3116: Sam Houston Forest, Texas, March 9 - 10, 2022

The image shows a close-up view of the underside of a May apple leaf with a rust fungus infection. The leaf is a medium green color and features large veins that run along its length. A reddish-brown patch can be seen on the surface of the leaf, which appears to be an area where the fungus has infected the plant.

The affected area is covered in small, orange-red spores that are clustered together in a circular pattern. These spores are likely the result of the fungus's reproductive cycle and are responsible for spreading the infection to other plants.

In the background of the image, it appears that there may be some dirt or debris on the surface where the leaf is growing. This could potentially provide an environment conducive to the growth of the fungus.

Overall, the image suggests that the May apple plant has been infected by a rust fungus, which can cause damage to the leaves and potentially harm the plant's ability to photosynthesize. – AI vision

🇪🇸 Descripción en español / Spanish Description

El lado inferior de una hoja de manzano de mayo (Podophyllum peltatum) con aecia del hongo de la roya del manzano Allodus podophylli (Puccinia podophylli) en el sendero Caney Creek (Sendero Little Lake Creek Loop) en el Bosque Nacional Sam Houston al norte de Montgomery, Texas, el 10 de marzo de 2022. La imagen muestra una vista detallada del lado inferior de una hoja de manzano de mayo con una infección por hongo de la roya. La hoja es de color verde medio y tiene grandes venas que discurren a lo largo de su longitud. Se puede observar un parche marrón rojizo en la superficie de la hoja, que parece ser una zona donde el hongo ha infectado la planta. El área afectada está cubierta de esporas naranja-rojizas pequeñas agrupadas en un patrón circular. Estas esporas son probablemente el resultado del ciclo reproductivo del hongo y son responsables de propagar la infección a otras plantas. En el fondo de la imagen, parece haber algo de suciedad o residuos en la superficie donde crece la hoja. Esto podría proporcionar un entorno propicio para el crecimiento del hongo. En general, la imagen sugiere que la planta de manzano de mayo ha sido infectada por un hongo de la roya, lo que puede dañar las hojas y potencialmente perjudicar la capacidad de la planta para realizar la fotosíntesis. – Spanish translation
