Hypotrachynaformosana (Zahlbr.) Hale (1975), based on Parmeliaformosana Zahlbruckner (1934), is a common, easily recognized foliose lichen in subtropical and temperate zones of South Korea, Japan, Taiwan, Thailand, Australia, Africa, Central and South America, and eastern United States. It is distinct in its cortical pustules, sublinear lobes, and dichotomously branched rhizines and belongs to the Hypotrachyna livida group. The secondary-product chemistry is uniform: lichexanthone and colensoinic, norcolensoinic, physodic, lividic, 4-O-demethylphysodic, and oxyphysodic acids. While one of us (M.E.H.) was preparing a monograph of Xanthoparmelia, the type of Parmelia osseoalba Vainio (1921), reported to be a Xanthoparmelia, was found to be identical morphologically and chemically to H. formosana. Therefore P. formosana is incorrect as it is a later synonym (Art. 11.3, ICBN). Parmelia osseoalba is the earliest legitimate name and a new combination is required in Hypotrachyna:
