ABSTRACT. Records of Scapania verrucosa from the Russian Far East have recently been considered as dubious or erroneous. Revision of all available collections, however, confirms the older records and detects new localities in Primorsky Territory. All specimens from Magadan Province and Khabarovsk Territory were transferred to S. microdonta. Thus, it is shown that in Russia S. verrucosa sporadically occurs only in the southern Far East and the Caucasus. Description and illustrations of S. verrucosa are provided, and examined specimens are listed.
