摘要

The genus Parmotrema in mainland China has been revised and 37 species are recognized. Of these Parmotrema laeve is reported as a new combination, 12 species are reported as new to China [P. applanatum, P. andinum, P. deflectens, P. eunetum, P. gardneri, P. immiscens, P. louisianae, P. margaritatum, P. pseudotinctorum, P. sipmanii, P. subarnoldii and P subochraceum] and 3 species are recorded in mainland China for the first time [P. dilatatum, P. permutatum, and P. subcorallinum]. Parmotrema subtropicum is reduced to synonymy with P. overeemii, while the occurrence of 6 species reported previously could not been confirmed [P latissimum, R conformatum, P. hababianum, P. perforatum, P. sulphuratum and P zollingeri].
