Album 3368: College Station - Sam Houston Forest, Texas, March 19 - 22, 2023

The image presents a detailed view of bright orange cups of Mayapple Rust Fungus (Allodus podophylli, formerly known as Puccinia podophylli) on the underside of May Apple leaves. The leaves are green with water droplets and feature five leaflets with serrated edges.

**Fungal Growth:**

The fungal growth is characterized by bright orange cups that have formed on the underside of a single May Apple leaf. These structures resemble tiny, rounded mushrooms and are densely packed, covering most of the leaf's surface.

**Background:**

In the background, additional leaves covered in similar fungus can be seen at the top right of the image. The blurred dark brown area behind the leaf is likely composed of twigs or dead plant material on the forest floor.

**Overall Context:**

The image was captured in Sam Houston National Forest, north of Montgomery, Texas, on March 21, 2023. It appears that the fungus has recently begun to grow and spread across the leaves, as indicated by the bright orange coloration. – AI vision
