Parmotrema tinctorum is a foliose lichen species characterized by its gray to gray-brown thallus with lobes 2-5 mm wide, cilia present along the lobe margins, and apothecia that are marginal to submarginal. In East and Central Texas, it grows on trees, particularly oak and cedar, in shaded to partially shaded areas. It is commonly found in woodland edges, riparian zones, and urban landscapes, often thriving in areas with moderate to high humidity and minimal air pollution. The species is relatively common in the region, with a wide distribution across the eastern and central parts of the state.
Observations of Parmotrema tinctorum in East and Central Texas show that the species is widely distributed across the region. It was found growing on various tree species, including Yaupon holly, oak, and other unidentified trees. The lichen was observed on both living trees, such as thin trunks and branches, and dead trees, like fallen logs. Locations with sightings include Lick Creek Park in College Station, Lake Somerville Trailway, Lone Star Hiking Trail in Sam Houston National Forest near Huntsville, and Caney Creek Trail. The observations span from January to November, indicating that the species is present throughout the year. Multiple sightings were recorded at different locations within Sam Houston National Forest, suggesting a strong presence of Parmotrema tinctorum in this area. The lichen's ability to grow on various substrates and its widespread distribution are notable characteristics.
