Recognized by sight: Cilia but sparse rhizines and broad somewhat-ruffled lobes. This specimen doesn’t show soralia yet and is somewhat intermediate in other aspects, so species is unknown. P. chinense seems to be the common one up there, but could also be P. arnoldii (longer cilia, medulla K-) or P. crinitum (laminal isidia instead of marginal pillows of soredia)
