Tiny bright orange cups on aecia of mayapple rust fungus (Allodus podophylli, Puccinia podophylli) underside of a leaf of May apple (Podophyllum peltatum) on Caney Creek Trail (Little Lake Creek Loop Trail) in Sam Houston National Forest near Huntsville. Texas

🎞️ #2468-05

This image presents a close-up view of an underside leaf surface of a May Apple plant (Podophyllum peltatum), featuring clusters of tiny bright orange cups on its aecia.

The May Apple's green leaves display veins with visible ridges that run perpendicular to each other, indicating the presence of chloroplasts. On the leaf's underside, numerous small, roundish structures are clustered together in groups. These structures resemble tiny cups or bowls and have a vibrant orange hue. Some of these clusters appear to be attached to what resembles a thin white membrane.

The leaves seem to be resting on top of other plant material, which is visible around them. The overall appearance suggests the presence of a fungus, likely Allodus podophylli (Puccinia podophylli), also known as May Apple rust fungus. This fungus commonly affects plants in the Berberidaceae family and can cause damage by forming galls on the leaves or stems.

The image was captured on March 16th, 2019, during a hike along the Caney Creek Trail (Little Lake Creek Loop Trail) within Sam Houston National Forest near Huntsville, Texas. – AI vision

Texas, 16 de marzo de 2019. La imagen presenta una vista detallada de la superficie inferior de la hoja de una planta de manzana podredumbre (Podophyllum peltatum), con agrupaciones de pequeñas copas naranjas brillantes en su aecia. Las hojas verdes de la manzana podredumbre presentan venas con aristas visibles que se extienden perpendiculares entre sí, lo que indica la presencia de cloroplastos. En el lado inferior de la hoja, se agrupan numerosas estructuras redondas en grupos. Estas estructuras se asemejan a pequeñas copas o tazones y tienen un tono naranja vibrante. Algunos de estos agrupamientos parecen estar unidos a lo que parece una membrana blanca delgada. Las hojas parecen descansar encima de otro material vegetal, visible alrededor de ellas.
