The photograph showcases a cluster of greenish-gray lichens with irregularly shaped lobes and ruffles along their margins, featuring small holes that appear to have been punched through each one.
These distinctive features are likely responsible for the common name "Perforated Ruffle Lichen" (Parmotrema perforatum). The lichens are growing on a thin oak twig in Lick Creek Park in College Station, Texas. This location is within the southeastern United States, which is part of Parmotrema perforatum's range.
