“…The species is widely recognized by the common name "Lace Lichen" (Brodo & al., 2001), which is well over a century old (Tuckerman, 1872), and has been formally designated the State Lichen of California (California Lichen Society, 2015), the only such designation in the United States. It is used as nesting material by birds (Williams & al., 1958;Brodo & al., 2001), browsed by animals (Doell, 2002), and has numerous documented cultural uses in western North America including by indigenous peoples (Goodrich & al., 1980;Zigmond, 1981;Villella, 2016). The species was recently ranked Least Concern on the IUCN Red List (Reese Naesborg, 2022).…”
