Abstract
Through an examination of axillary hairs, Mitten's transfer of Phascum jamesoni to Bartramia as B. humilis is supported, and the combination of Conostomum jamesoni (Tayl.) Steere is reduced to synonymy under Mitten's species. Based on axillary hair morphology, Bartramia rosea Herzog is considered to be a synonym of Anacolia laevisphaera (TayI.) Flows.
