Underside of a leaf of May apple (mandrake, Podophyllum peltatum) with brown teleutospores of mayapple rust fungus Allodus podophylli (Puccinia podophylli) on Caney Creek Trail (Little Lake Creek Loop Trail) in Sam Houston National Forest, near Huntsville. Texas

🎞️ #2255-16

The image depicts the underside of a leaf from the may apple plant, specifically exhibiting brown teleutospores of the mayapple rust fungus (Allodus podophylli). These spores are characterized by their brown color and irregular shape, with some appearing more spherical or oval in form.

The leaves themselves display a light green hue with prominent veins that branch out from the central vein. The leaf's underside is covered with numerous dark brown teleutospores scattered across its surface. Some of these spores are clustered together in small groups, while others appear solitary.

Given the context provided by the caption and image, it can be inferred that this photograph was taken during a hike on May 5th, likely for educational or scientific purposes related to botany or mycology. The presence of teleutospores suggests that the fungus is actively reproducing at this time. – AI vision
