Phyllopsora confusa is a crustose lichen that grows on bark, typically found in shaded to partially shaded areas. In East and Central Texas, it occurs on deciduous trees, particularly oak, elm, and maple. The thallus is pale greenish-gray to gray, with a smooth to slightly wrinkled surface, and lacks distinct vegetative propagules. Apothecia are rare, but when present, they are immersed to slightly raised, with a pale brown to brown disc. The species is relatively common in the region, particularly in areas with rich soil and moderate to high humidity.
Observations of Phyllopsora confusa in East and Central Texas reveal its presence on various trees in the region. On January 26, 2019, it was found growing on an oak tree along Caney Creek in Sam Houston National Forest near Huntsville. Similarly, on February 1, 2019, it was observed on a tree near a creek in Big Creek Scenic Area of the same forest, but closer to Shepherd, Texas. Another sighting occurred on March 2, 2019, on a tree along Caney Creek Trail, also within Sam Houston National Forest. These observations indicate that Phyllopsora confusa is widespread in the area, preferring trees near water sources. The lichen's growth was documented over several months, suggesting it thrives in the local climate conditions of East and Central Texas during winter to early spring. Its habitat seems to include oak trees and those in proximity to creeks.
